[英]How do i get last photo's path from photo library?
我正在使用這種方法進行屏幕捕獲:
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage*theImage=UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(theImage, nil, nil, nil);
我想獲取該照片的路徑,以便可以將其與Instagram方法一起使用
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", lastphotoTaken]];
// NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", lastphotoTaken]];
self.dic.UTI = @"com.instagram.exclusivegram";
self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
self.dic.annotation = [NSDictionary dictionaryWithObject:@"Here Give what you want to share" forKey:@"InstagramCaption"];
[self.dic presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
感謝名單
無法使用以下方法獲取資產網址:
UIImageWriteToSavedPhotosAlbum(theImage, nil, nil, nil);
相反,您可以使用:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeImageToSavedPhotosAlbum:[theImageCGImage] orientation:(ALAssetOrientation)[theImageimageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){
if (error)
{
NSLog(@"Ooops!");
}
else
{
NSLog(@"Saved URL : %@", assetURL);
}
}];
[library release];
