[英]How to load captured image from photo album
I have a button to capture picture then it save to photoAlbum. 我有一个按钮来捕获图片,然后将其保存到photoAlbum。 I used another button for load image from using
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
我使用
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
使用另一个按钮加载图像imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
then i implemented didFinishPickingMediaWithInfo:
for loading photo album to newImage. 然后我实现
didFinishPickingMediaWithInfo:
用于将相册加载到newImage。 My need is after capture photo i have alertview then click YES button automatically load last captured image PhotoAlbum and add newImage. 我的需要是在捕获照片后,我具有alertview,然后单击“是”按钮,自动加载最后捕获的图像PhotoAlbum并添加newImage。 Is it possible?
可能吗?
- (void)saveImageToPhotoAlbum
{
[self.library saveImage:[self stillImage] toAlbum:@"Album" withCompletionBlock:^(NSError *error) {
if (error!=nil) {
NSLog(@"Big error: %@", [error description]);
}
}];
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Gallery"
message:@"Do you want to use the captured image?" delegate:self
cancelButtonTitle:@"Cancel" otherButtonTitles:@"Yes", nil];
alertView.tag = 2;
[alertView show];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
//set image
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
newImage = [[UIImageView alloc] initWithImage:[info objectForKey:UIImagePickerControllerOriginalImage]];
[newImage setFrame:CGRectMake(0, 0, 320, 568)];
[self.view addSubView:newImage];
}
I need to display last captured image to newImage click of alertView button: 我需要将最后捕获的图像显示为newImage,然后单击alertView按钮:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
// the user clicked one of the OK/Cancel buttons
if (buttonIndex == 1){
}
}
Before use below code take UIImage *img in .h file
- (void)saveImageToPhotoAlbum
{
[self.library saveImage:[self stillImage] toAlbum:@"Album" withCompletionBlock:^(NSError *error) {
if (error!=nil) {
NSLog(@"Big error: %@", [error description]);
}
}];
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Gallery"
message:@"Do you want to use the captured image?" delegate:self
cancelButtonTitle:@"Cancel" otherButtonTitles:@"Yes", nil];
alertView.tag = 2;
[alertView show];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
//set image
img=nil;
img=[info objectForKey:UIImagePickerControllerOriginalImage];
[self saveImageToPhotoAlbum];
// [self dismissViewControllerAnimated:YES completion:nil];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 1)
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if(newImage)
{
[newImage removeFromSuperview];
newImage=nil;
}
newImage = [[UIImageView alloc] initWithImage:img];
[newImage setFrame:CGRectMake(0, 0, 320, 568)];
[self.view addSubView:newImage];
}
[picker dismissViewControllerAnimated:YES completion:nil];
}
else
{
img=nil;
[picker dismissViewControllerAnimated:YES completion:nil];
}
}
