Photo Library view stays on screen after choosing an image with UIImagePickerController

Question
After I choose a picture through the UIImagePickerController interface from the Photo Library, the Photo Library view stays displayed, even though I've called dismissModelViewControllerAnimated in imagePickerController:didFinishPickingImage:editingInfo.
Has anyone seen this? These are the three relevant methods I'm using:
- (IBAction)choosePictureFromLibrary:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsImageEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
[picker release];
}
else {
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Error accessing Photo Library" message:@"This device does not support a Photo Library." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
}
- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingImage:(UIImage*)image editingInfo:(NSDictionary*)editingInfo {
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Picture picked!" message:@"You picked a picture!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
[picker dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController*)picker {
[picker dismissModalViewControllerAnimated:YES];
}
I would have thought that calling imagePickerController:didFinishPickingImage:editingInfo would completely dismiss the Photo Library view, but it doesn't seem to. Is there anything else I have to do to make it go away?
Solution
You need to access the viewController of the picker not the picker itself. Try this line instead.
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
OTHER TIPS
You can just call
[self dismissModalViewControllerAnimated:YES];
to dismiss any modal view controller on top of the current view.
This makes sense since you present the view controller by calling:
[self presentModalViewController:picker animated:YES];
Just an update to the answers to this
[self dismissModalViewControllerAnimated:YES];
has been deprecated in iOS 6.0
so you now need to use.
[self dismissViewControllerAnimated:YES completion:nil];
Not a huge change but for anyone that looks at this question and they are using iOS 6.0 they will need an updated answer.
[self presentModalViewController:filePicker animated:YES];
has also been deprecated in favor of
[self presentViewController:filePicker animated:YES completion:nil];
