How to add a UIViewController as a subview to a UIViewController(RootViewController)?

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?

Try to set frame to your enroll screen object then add it as a subview to loginview. Ex:

[enrollViewcontroller.view setFrame:CGRectMake(0,0,320,440)];
[self.view addsubview:enrollViewcontroller.view];

change the frame according to your requirement. Because it is 20 pixel down try to change the y axis position like this CGRectMake(0,-20,320,440) and check.

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.

Instead of adding a UIViewController as a subview to another UIViewController, I have decided to present my ViewController as a ModalViewController using

[self presentModalViewController:myViewController animated:YES];
