Answer 1

My Opinion:

self.window.rootViewController will resize the rootViewController.view according to status bar height

But if you use addSubview it won't

For example, if you setRootViewController to a NavigationController, the navigationController would be (0,0,320,480);

but if you setRootViewController to a common UIViewController, the navigationController would be (0,0,320,460);

if you use addSubview: the two viewcontrollers would be (0,0,320,480)

And if there is an In-call-StatusBar. it also change for you when you use setRoot... if you use addSubview, the subview size wouldn't change

do some test with different view border color
