I din't quite understand what you mean by
"... using the autoresizingMasks ..."
I did the same with UIIView animation. There are plenty of other techniques also out there.
here is my code:
-(void)rotateToLandscape
{
UIWindow *win = [[UIApplication sharedApplication]keyWindow];
if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){
[[[UIApplication sharedApplication] keyWindow] setBackgroundColor:[UIColor blackColor]];
[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:0.3];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
win.transform = CGAffineTransformIdentity;
win.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
win.bounds = CGRectMake(0.0f, 0.0f, 480, 320);
win.center = CGPointMake(160.0f, 240.0f);
[UIView commitAnimations];
}
}
// I hope the code doesn't need explanation.
//You can remove the animation statements to get the effect you want (un-animated).
