Unbalanced calls to begin/end appearance transitions for

Question

I have this problem when I simulate my app, its not an error or a warning but it appears in my console, has anyone ever experienced this before?

Answer 1

The situation can occur if you are adding a view with a modal view controller as a sub view. Best to use:

-(void) viewDidAppear:(BOOL)animated {
    [self presentViewController:self.yourModalVC animated:YES completion:nil];
}

It is basically saying the view life cycle is not streamlined for those viewControllers you are trying to display then.
