statusbar and superview frame size

I've a typical View based application (mainwindow.xib + viewControler.xib) in which I have HIDDEN the status in the AppDelegate file like this...

[[UIApplication sharedApplication] setStatusBarHidden:YES];

then I create various subviews on the mainview (mainly UIWebViews) that are full screen positioned at 0,0. Then I created a button that enables you to toggle the view of the statusbar. My problem begins when I show the statusbar and the change the orientation of th开发者_C百科e screen, the views don't have the full dimension of window and are starting just after the statusbar (at y:20 instead of y:0) and their height is reduced by 20pixel and if I removed the status I can see the blank space.

So the question is this...how can the code ignore the presence of the statusbar and always position new or re-oriented views into 0,0, instead of 0,20 (if the statusbar is shown). I think that the problem is not lying on my main view but in my MainWindow.xib, but I cannot find any solution.

UPDATE1: I am also checking for a solution in the autoresizingmask property of the subviews.

Thanx in advance...

I finally found the solution and I can fall to sleep in peace.

The solution lies in the property wantsFullScreenLayout and you must set it to YES. So visit your appDelegate that adds your mainview (superview) and add this line:

viewController.wantsFullScreenLayout = YES;

before this line

 [window addSubview:viewController.view];

on didFinishLaunchingWithOptions of your AppDelegate.m file.

That way your superview ALWAYS uses fullscreen resolution and doesn't resize if the statusbar is present!
