Question

I have a UIViewController named LoginViewController, and it is a rootViewController in the AppDelegate. In the LoginViewController, I have two buttons: Login and Enroll.

When I tap Login, I assign a TabBarController as the rootViewController, then show the TabBarController. However, now I think I need to add another UIViewcController as a subview when I tap Enroll. I tried the following:

[self.view addsubview:viewcontroller.view];

But the problem here is My ViewController’s view.top is pinned about 20 pixels below the top of the screen. I think there is an issue with the status bar, but I can’t figure out how to fix it.

I think that I need to add my ViewController as a subview to the LoginViewController, then redirect from there to different views. Can someone please suggest other options?

Answer 1

You should not make a UIViewController a subview of another UIViewController’s view. What you likely want to do if treat the subview as a normal UIView (if not both of those views) so that you only have one UIViewController on screen and it occupies the entire screen.
