how to rotate view when device orientation changes keeping the correct size of window

Question

I want to support full device orientation in my iPad app which uses cocos2d. To accomplish this I thought I'll return YES for shouldAutorotateToInterfaceOrientation like before when I was working on apps without cocos2d, but in this case my view doesn't resize properly. To show you with what I ended up, it's example picture.

you can see that orientation is landscape but the view is still portrait. Can anybody tell me what am I doing wrong?

Answer 1

Add the following function and perform respective changes

-(void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    switch (toInterfaceOrientation) {
        case UIInterfaceOrientationPortrait:
            break;
        case UIInterfaceOrientationLandscapeLeft:
            break;
        case UIInterfaceOrientationLandscapeRight:
            break;
        case UIInterfaceOrientationPortraitUpsideDown:
            break;
        default:
            break;
    }
}

You have to set the autosize property of your view. the quick way is to set it in the "size inspector"
