Google Sign In showing blank screen in iOS

Question

I have implemented code as per the google SDK documentation line by line in my app, but still when I click on google sign in button app shifts to new view controller with webvie

Answer 1

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. :)
