Problem opening new ViewController after UIImagePickerController

Question

I am trying to open up a new view (UnprocessedPhotoViewController) immediately after the delegate function for my UIImagePickerController returns a \"didFinishPickingImage\".

Answer 1

Another way to do this is to wrap the built-in dismissal animation with your own animation, and then catch the animationDidStop "event." This creates a composite animation, so when the built-in animation is done, your (empty) wrapper animation finishes you and alerts you that you're done.

This is slightly cleaner than the other answer here, IMO, as you don't need to keep a state variable or override viewDidAppear: (in my app, the view controller presenting the picker is quite a few objects removed from the utility code that handles picker management, and that would mean any view controller using my shared utility would have to override viewDidAppear:, or else fail to work):

-(void)dismissalAnimationDone:(NSString*)animationID 
                     finished:(BOOL)finished context:(void*)context
{
    UIImage* image = (UIImage*) context;
    // present controllers as you please
}

-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
    [UIView beginAnimations:@"dismissal wrapper" context:image];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(dismissalAnimationDone:finished:context:)];

    [self.delegate dismissModalViewControllerAnimated:YES];

    [UIView commitAnimations];
}
