Answer 1

I have the same problem. I use the UIAlertView to confirm user really want to do authorization. It will show the blank screen. If I remove the UIAlertView and show the authorization view directly. It works fine. The problem also show in the Dropbox authorization screen. If you not use UIAlertView , please try to pass the top most controller

Finally after so many days found the problem. I was showing splash view from my appDelegate using refrence of UIWindow which was adding and removing an imgview as subview to the window. So it was somehow messing with the UINavigation's stack and my view controller was not getting any reference to the UINavigationController. After removing that code it's working just fine. Also came to the solution that, if I want to show splash screen, as I can't use UIWindow's reference, I have to add new VC and write my all navigation code there. @TedYu Thank you very much for the help. :)
