Question

I started by creating a universal window based app. Starting with the iPhone version I created a UIViewController and associated nib.

My App delegate:

rootViewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
[window makeKeyAndVisible];
[window addSubview:rootViewController.view];
return YES;

My RootViewController:

- (void)viewDidLoad {
[super viewDidLoad];
adBannerView = [[ADBannerView alloc] initWithFrame:CGRectZero()];
[self.view addSubview:adBannerView];

}

I’ve tried instanciating buttons instead of the adBanner and I get the same result.

My RootViewController’s nib has not been changed since x-code created it for me.
My MainWindow_iPhone.xib also is stock.

What’s causing this?

Update

After changing the app’s orientation the adBannerView (or button…) will snap into the correct place at y=0. I’ve tried setting adBannerView’s y location to 20 presumably to compensate for the status bar and that makes everything display correctly until I change orientation. Then everything moves down 20 pixels and will leave a 20 pixel space between the adBannerView and the status bar.

Try to add the next line in your viewDidLoad (right after [super viewDidLoad];):

self.view.frame = [[UIScreen mainScreen] applicationFrame];
