How to change the orientation of UIWindow in iPad

Question

I want to create something like that a UIView slide down for the status bar in iPad. But it only work in portrait mode. When I rotate the iPad to landscape mode, the UIView still slide as portrait mode.

Answer 1

This is because you are adding it to window

If you add an additional view controller's UIView property to UIWindow (at the same level as your primary view controller) via the following:

[myWindow addSubview:anotherController.view];

this additional view controller will not receive rotation events and will never rotate. Only the first view controller added to UIWindow will rotate.

So try this :

UIWindow* window = [UIApplication sharedApplication].keyWindow;
if (!window) 
    window = [[UIApplication sharedApplication].windows objectAtIndex:0];
[[[window subviews] objectAtIndex:0] addSubview:myView];    

Answer 2

You should try:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

Just put it in your viewcontroller.m file.
