[英]How to share an image on Instagram in iOS?
我的客户想在 Instagram、Twitter、Facebook 上分享一张图片。
我做过 Twitter 和 Facebook,但没有在互联网上找到任何 API 或任何东西来在 Instagram 上分享图像。 是否可以在 Instagram 上分享图片? 如果是那么怎么办?
当我查看 Instagram 的开发者网站时,我发现了 Ruby on Rails 和 Python 的库。 但是没有iOS Sdk的文档
我已经根据 instagram.com/developer 从 instagram 获得令牌,但现在不知道下一步要做什么才能与 instagram 图片共享。
最后我得到了答案。 你不能直接在 Instagram 上发布图片。 您必须使用 UIDocumentInteractionController 重新定向您的图像。
@property (nonatomic, retain) UIDocumentInteractionController *dic;
CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
self.dic.UTI = @"com.instagram.photo";
self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
[self.dic presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
注意:一旦您重定向到 instagram 应用程序,您将无法返回到您的应用程序。 你必须再次打开你的应用程序
从这里下载源
这是一个完整的测试代码,用于将图像 + 标题文本上传到 Instagram。
在.h文件
//Instagram
@property (nonatomic, retain) UIDocumentInteractionController *documentController;
-(void)instaGramWallPost
{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not
{
NSData *imageData = UIImagePNGRepresentation(imge); //convert image into .png format.
NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it
NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"insta.igo"]]; //add our image to the path
[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image)
NSLog(@"image saved");
CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString *fileNameToSave = [NSString stringWithFormat:@"Documents/insta.igo"];
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:fileNameToSave];
NSLog(@"jpg path %@",jpgPath);
NSString *newJpgPath = [NSString stringWithFormat:@"file://%@",jpgPath];
NSLog(@"with File path %@",newJpgPath);
NSURL *igImageHookFile = [[NSURL alloc]initFileURLWithPath:newJpgPath];
NSLog(@"url Path %@",igImageHookFile);
self.documentController.UTI = @"com.instagram.exclusivegram";
self.documentController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.documentController=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
NSString *caption = @"#Your Text"; //settext as Default Caption
self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"%@",caption],@"InstagramCaption", nil];
[self.documentController presentOpenInMenuFromRect:rect inView: self.view animated:YES];
}
else
{
NSLog (@"Instagram not found");
}
}
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
NSLog(@"file url %@",fileURL);
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
要么
-(void)instaGramWallPost
{
NSURL *myURL = [NSURL URLWithString:@"Your image url"];
NSData * imageData = [[NSData alloc] initWithContentsOfURL:myURL];
UIImage *imgShare = [[UIImage alloc] initWithData:imageData];
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not
{
UIImage *imageToUse = imgShare;
NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Image.igo"];
NSData *imageData=UIImagePNGRepresentation(imageToUse);
[imageData writeToFile:saveImagePath atomically:YES];
NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath];
self.documentController=[[UIDocumentInteractionController alloc]init];
self.documentController = [UIDocumentInteractionController interactionControllerWithURL:imageURL];
self.documentController.delegate = self;
self.documentController.annotation = [NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"Testing"], @"InstagramCaption", nil];
self.documentController.UTI = @"com.instagram.exclusivegram";
UIViewController *vc = [UIApplication sharedApplication].keyWindow.rootViewController;
[self.documentController presentOpenInMenuFromRect:CGRectMake(1, 1, 1, 1) inView:vc.view animated:YES];
}
else {
DisplayAlertWithTitle(@"Instagram not found", @"")
}
}
并将其写入.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>instagram</string>
</array>
您可以使用 Instagram 网址方案提供的其中一种
Instagram官方文档在这里
与 UIDocumentInteractionController 共享
final class InstagramPublisher: NSObject { private var documentsController:UIDocumentInteractionController = UIDocumentInteractionController() func postImage(image: UIImage, view: UIView, result:((Bool)->Void)? = nil) { guard let instagramURL = NSURL(string: "instagram://app") else { if let result = result { result(false) } return } if UIApplication.sharedApplication().canOpenURL(instagramURL) { let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagrammFotoToShareName.igo") if let image = UIImageJPEGRepresentation(image, 1.0) { image.writeToFile(jpgPath, atomically: true) let fileURL = NSURL.fileURLWithPath(jpgPath) documentsController.URL = fileURL documentsController.UTI = "com.instagram.exclusivegram" documentsController.presentOpenInMenuFromRect(view.bounds, inView: view, animated: true) if let result = result { result(true) } } else if let result = result { result(false) } } else { if let result = result { result(false) } } } }
与直接重定向分享
import Photos final class InstagramPublisher: NSObject { func postImage(image: UIImage, result:((Bool)->Void)? = nil) { guard let instagramURL = NSURL(string: "instagram://app") else { if let result = result { result(false) } return } let image = image.scaleImageWithAspectToWidth(640) do { try PHPhotoLibrary.sharedPhotoLibrary().performChangesAndWait { let request = PHAssetChangeRequest.creationRequestForAssetFromImage(image) let assetID = request.placeholderForCreatedAsset?.localIdentifier?? "" let shareURL = "instagram://library?LocalIdentifier=" + assetID if UIApplication.sharedApplication().canOpenURL(instagramURL) { if let urlForRedirect = NSURL(string: shareURL) { UIApplication.sharedApplication().openURL(urlForRedirect) } } } } catch { if let result = result { result(false) } } } }
将照片调整为推荐尺寸的扩展
import UIKit extension UIImage { // MARK: - UIImage+Resize func scaleImageWithAspectToWidth(toWidth:CGFloat) -> UIImage { let oldWidth:CGFloat = size.width let scaleFactor:CGFloat = toWidth / oldWidth let newHeight = self.size.height * scaleFactor let newWidth = oldWidth * scaleFactor; UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight)) drawInRect(CGRectMake(0, 0, newWidth, newHeight)) let newImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() return newImage } }
不要忘记在 plist 中添加所需的方案
<key>LSApplicationQueriesSchemes</key> <array> <string>instagram</string> </array>
希望这个答案能解决您的疑问。 这将直接打开 Instagram 中的库文件夹而不是相机。
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSURL *videoFilePath = [NSURL URLWithString:[NSString stringWithFormat:@"%@",[request downloadDestinationPath]]]; // Your local path to the video
NSString *caption = @"Some Preloaded Caption";
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:videoFilePath completionBlock:^(NSURL *assetURL, NSError *error) {
NSString *escapedString = [self urlencodedString:videoFilePath.absoluteString];
NSString *escapedCaption = [self urlencodedString:caption];
NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",escapedString,escapedCaption]];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
[[UIApplication sharedApplication] openURL:instagramURL];
}
}];
如果你不想使用 UIDocumentInteractionController
import Photos
...
func postImageToInstagram(image: UIImage) {
UIImageWriteToSavedPhotosAlbum(image, self, #selector(SocialShare.image(_:didFinishSavingWithError:contextInfo:)), nil)
}
func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
if error != nil {
print(error)
}
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
let fetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
if let lastAsset = fetchResult.firstObject as? PHAsset {
let localIdentifier = lastAsset.localIdentifier
let u = "instagram://library?LocalIdentifier=" + localIdentifier
let url = NSURL(string: u)!
if UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.sharedApplication().openURL(NSURL(string: u)!)
} else {
let alertController = UIAlertController(title: "Error", message: "Instagram is not installed", preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
}
}
}
对于 iOS 6 及更高版本,您可以使用此 UIActivity 将图像上传到 Instagram,它使用 iOS 挂钩具有相同的工作流程,但简化了开发:
这是我详细实施的正确答案。 在.h文件中
UIImageView *imageMain;
@property (nonatomic, strong) UIDocumentInteractionController *documentController;
in.m文件只写
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
CGFloat cropVal = (imageMain.image.size.height > imageMain.image.size.width ? imageMain.image.size.width : imageMain.image.size.height);
cropVal *= [imageMain.image scale];
CGRect cropRect = (CGRect){.size.height = cropVal, .size.width = cropVal};
CGImageRef imageRef = CGImageCreateWithImageInRect([imageMain.image CGImage], cropRect);
NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 1.0);
CGImageRelease(imageRef);
NSString *writePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"instagram.igo"];
if (![imageData writeToFile:writePath atomically:YES]) {
// failure
NSLog(@"image save failed to path %@", writePath);
return;
} else {
// success.
}
// send it to instagram.
NSURL *fileURL = [NSURL fileURLWithPath:writePath];
self.documentController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
self.documentController.delegate = self;
[self.documentController setUTI:@"com.instagram.exclusivegram"];
[self.documentController setAnnotation:@{@"InstagramCaption" : @"We are making fun"}];
[self.documentController presentOpenInMenuFromRect:CGRectMake(0, 0, 320, 480) inView:self.view animated:YES];
}
else
{
NSLog (@"Instagram not found");
}
你肯定会得到结果。 例如,您会从底部看到带有 instagram 图像的弹出窗口。单击它并享受乐趣。
我在我的应用程序中尝试过这个并且它运行良好(Swift)
import Foundation
import UIKit
class InstagramManager: NSObject, UIDocumentInteractionControllerDelegate {
private let kInstagramURL = "instagram://"
private let kUTI = "com.instagram.exclusivegram"
private let kfileNameExtension = "instagram.igo"
private let kAlertViewTitle = "Error"
private let kAlertViewMessage = "Please install the Instagram application"
var documentInteractionController = UIDocumentInteractionController()
// singleton manager
class var sharedManager: InstagramManager {
struct Singleton {
static let instance = InstagramManager()
}
return Singleton.instance
}
func postImageToInstagramWithCaption(imageInstagram: UIImage, instagramCaption: String, view: UIView) {
// called to post image with caption to the instagram application
let instagramURL = NSURL(string: kInstagramURL)
if UIApplication.sharedApplication().canOpenURL(instagramURL!) {
let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent(kfileNameExtension)
UIImageJPEGRepresentation(imageInstagram, 1.0)!.writeToFile(jpgPath, atomically: true)
let rect = CGRectMake(0,0,612,612)
let fileURL = NSURL.fileURLWithPath(jpgPath)
documentInteractionController.URL = fileURL
documentInteractionController.delegate = self
documentInteractionController.UTI = kUTI
// adding caption for the image
documentInteractionController.annotation = ["InstagramCaption": instagramCaption]
documentInteractionController.presentOpenInMenuFromRect(rect, inView: view, animated: true)
}
else {
// alert displayed when the instagram application is not available in the device
UIAlertView(title: kAlertViewTitle, message: kAlertViewMessage, delegate:nil, cancelButtonTitle:"Ok").show()
}
}
}
func sendToInstagram(){
let image = postImage
InstagramManager.sharedManager.postImageToInstagramWithCaption(image!, instagramCaption: "\(description)", view: self.view)
}
这是正确答案。 您不能直接在 Instagram 上发布图片。 您需要使用 UIDocumentInteractionController 重定向到 Instagram...
NSString* imagePath = [NSString stringWithFormat:@"%@/instagramShare.igo", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
[[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];
UIImage *instagramImage = [UIImage imageNamed:@"imagename you want to share"];
[UIImagePNGRepresentation(instagramImage) writeToFile:imagePath atomically:YES];
NSLog(@"Image Size >>> %@", NSStringFromCGSize(instagramImage.size));
self.dic=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];
self.dic.delegate = self;
self.dic.UTI = @"com.instagram.exclusivegram";
[self.dic presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];
注意:一旦您重定向到 instagram 应用程序,您将无法返回到您的应用程序。 你必须再次打开你的应用程序
您可以在不使用 UIDocumentInteractionController 的情况下执行此操作,并使用以下 3 种方法直接进入 Instagram:
它的工作原理与所有其他著名应用程序一样。 代码是用 Objective c 编写的,因此您可以根据需要将其转换为 swift。 您需要做的是将图像保存到设备并使用 URLScheme
将其添加到您的.m 文件中
#import <Photos/Photos.h>
首先,您需要使用此方法将 UIImage 保存到设备:
-(void)savePostsPhotoBeforeSharing
{
UIImageWriteToSavedPhotosAlbum([UIImage imageNamed:@"image_file_name.jpg"], self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
此方法是将图像保存到您的设备的回调:
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
[self sharePostOnInstagram];
}
图片保存到设备后,需要查询刚刚保存的图片,获取为PHAsset
-(void)sharePostOnInstagram
{
PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO],];
__block PHAsset *assetToShare;
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
[result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {
assetToShare = asset;
}];
if([assetToShare isKindOfClass:[PHAsset class]])
{
NSString *localIdentifier = assetToShare.localIdentifier;
NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
NSURL *instagramURL = [NSURL URLWithString:urlString];
if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
{
[[UIApplication sharedApplication] openURL: instagramURL];
} else
{
// can not share with whats app
NSLog(@"No instagram installed");
}
}
}
并且不要忘记将它放在LSApplicationQueriesSchemes
下的 info.plist 中
<string>instagram</string>
- (void) shareImageWithInstagram
{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
UICachedFileMgr* mgr = _gCachedManger;
UIImage* photoImage = [mgr imageWithUrl:_imageView.image];
NSData* imageData = UIImagePNGRepresentation(photoImage);
NSString* captionString = [NSString stringWithFormat:@"ANY_TAG",];
NSString* imagePath = [UIUtils documentDirectoryWithSubpath:@"image.igo"];
[imageData writeToFile:imagePath atomically:NO];
NSURL* fileURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"file://%@",imagePath]];
self.docFile = [[self setupControllerWithURL:fileURL usingDelegate:self]retain];
self.docFile.annotation = [NSDictionary dictionaryWithObject: captionString
forKey:@"InstagramCaption"];
self.docFile.UTI = @"com.instagram.photo";
// OPEN THE HOOK
[self.docFile presentOpenInMenuFromRect:self.view.frame inView:self.view animated:YES];
}
else
{
[UIUtils messageAlert:@"Instagram not installed in this device!\nTo share image please install instagram." title:nil delegate:nil];
}
}
我在我的应用程序中尝试过这个,它肯定会工作
至于我,这里描述的最好和最简单的方法从我的 iOS 应用程序将照片分享到 Instagram
您需要使用 .igo 格式在设备上保存图像,然后使用“UIDocumentInteractionController”发送本地路径 Instagram 应用程序。 不要忘记设置“UIDocumentInteractionControllerDelegate”
我的建议是添加如下内容:
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
<your code>
}
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Insta_Images/%@",@"shareImage.png"]];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
docController.UTI = @"com.instagram.photo";
docController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
docController =[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
docController.delegate=self;
[docController presentOpenInMenuFromRect:CGRectMake(0 ,0 , 612, 612) inView:self.view animated:YES];
我注意到,如果您将指向图像的URL
放在activityItems
而不是UIImage
中, Copy to Instagram
活动项目本身就会出现,您无需执行任何其他操作。 请注意, activityItems
中的String
对象将被丢弃,并且无法在 Instagram 中预填充标题。 如果您仍然想提示用户发布特定的标题,您需要创建自定义活动,您可以在其中将该文本复制到剪贴板并让用户知道它,就像在这个要点中一样。
@import Photos;
-(void)shareOnInstagram:(UIImage*)imageInstagram {
[self authorizePHAssest:imageInstagram];
}
-(void)authorizePHAssest:(UIImage *)aImage{
PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
if (status == PHAuthorizationStatusAuthorized) {
// Access has been granted.
[self savePostsPhotoBeforeSharing:aImage];
}
else if (status == PHAuthorizationStatusDenied) {
// Access has been denied.
}
else if (status == PHAuthorizationStatusNotDetermined) {
// Access has not been determined.
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
if (status == PHAuthorizationStatusAuthorized) {
// Access has been granted.
[self savePostsPhotoBeforeSharing:aImage];
}
}];
}
else if (status == PHAuthorizationStatusRestricted) {
// Restricted access - normally won't happen.
}
}
-(void)saveImageInDeviceBeforeSharing:(UIImage *)aImage
{
UIImageWriteToSavedPhotosAlbum(aImage, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
if (error == nil){
[self sharePostOnInstagram];
}
}
-(void)shareImageOnInstagram
{
PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:false]];
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
__block PHAsset *assetToShare = [result firstObject];
if([assetToShare isKindOfClass:[PHAsset class]])
{
NSString *localIdentifier = assetToShare.localIdentifier;
NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
NSURL *instagramURL = [NSURL URLWithString:urlString];
if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
{
[[UIApplication sharedApplication] openURL:instagramURL options:@{} completionHandler:nil];
} else
{
NSLog(@"No instagram installed");
}
}
}
注意:- IMP TODO:- 在 Info.plist 中添加以下键
<key>LSApplicationQueriesSchemes</key>
<array>
<string>instagram</string>
</array>
我使用了这段代码:
NSString* filePathStr = [[NSBundle mainBundle] pathForResource:@"UMS_social_demo" ofType:@"png"];
NSURL* fileUrl = [NSURL fileURLWithPath:filePathStr];
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
[[NSData dataWithContentsOfURL:fileUrl] writeToFile:jpgPath atomically:YES];
NSURL* documentURL = [NSURL URLWithString:[NSString stringWithFormat:@"file://%@", jpgPath]];
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: documentURL];
self.interactionController = interactionController;
interactionController.delegate = self;
interactionController.UTI = @"com.instagram.photo";
CGRect rect = CGRectMake(0 ,0 , 0, 0);
[interactionController presentOpenInMenuFromRect:rect inView:self.view animated:YES];
-(void)shareOnInstagram {
CGRect rect = CGRectMake(self.view.frame.size.width*0.375 ,self.view.frame.size.height/2 , 0, 0);
NSString * saveImagePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/ShareInstragramImage.igo"];
[UIImagePNGRepresentation(_image) writeToFile:saveImagePath atomically:YES];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", saveImagePath]];
self.documentController=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
self.documentController.UTI = @"com.instagram.exclusivegram";
self.documentController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
[self.documentController presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
}
-(UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
NSURL *myURL = [NSURL URLWithString:sampleImageURL];
NSData * imageData = [[NSData alloc] initWithContentsOfURL:myURL];
UIImage *imageToUse = [[UIImage alloc] initWithData:imageData];
NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Image.ig"];
[imageData writeToFile:saveImagePath atomically:YES];
NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath];
self.documentController = [UIDocumentInteractionController interactionControllerWithURL:imageURL];
self.documentController.delegate = self;
self.documentController.annotation = [NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@""], @"", nil];
self.documentController.UTI = @"com.instagram.exclusivegram";
[self.documentController presentOpenInMenuFromRect:CGRectMake(1, 1, 1, 1) inView:self.view animated:YES];
