Question

I use un UINavigationCtronller to navigate from to UIViewController A an UIViewController B.
On the view of the UIViewController B, I tap a button and call UIImagePicker

UIImagePickerController *ipc = [[UIImagePickerController alloc] init];

ipc.sourceType = UIImagePickerControllerSourceTypeCamera;

ipc.delegate = self;

ipc.allowsEditing = NO;

[self presentModalViewController:ipc animated:YES];

if I tap the ‘Cancel’ button of UIImagePicker, I call

-(void)imagePickerControllerDidCancel:(UIImagePickerController*)picker{



[picker dismissModalViewControllerAnimated:YES];

}

UI will return to UIViewController A rather than B

If I tap any place, app crashed.

Welcome any comment

Instead of

[picker dismissModalViewControllerAnimated:YES];

try

[picker.presentingViewController dismissModalViewControllerAnimated:YES];

You want the ViewController that is presenting the picker to dismiss, not the picker itself.
