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

In my case it happened when I triggered [self performSegueWithIdentifier:@"SomeIdentifier" sender:self]; within a UINavigationController item's viewDidLoad method.

Moving it into the viewDidAppear method solved the problem.

The reason very likely is that in viewDidLoad not all of the fancy animations have already been finished, whereas in viewDidAppear everything's done.
