Strange behavior when changing UIDeviceOrientation

Question

Here is what I do when I orientation changes...

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    if((self.interfaceOrientation == UIDeviceOrientationPortrait) || (self.interfaceOrientation == UIDeviceOrientationPortraitUpsideDown))
    {    
        [self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"auto_main_hor.png"]]];
        [UIView commitAnimations];

    } else if((self.interfaceOrientation == UIDeviceOrientationLandscapeLeft) || (self.interfaceOrientation == UIDeviceOrientationLandscapeRight))
    {
        [self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"auto_main_vert.png"]]];
    } 
}

When I rotate device for 180 degrees sharply I get some misdisplaying? how can I fix it?

Please note that UIInterfaceOrientation and UIDeviceOrientation are not the same thing. You are using the device orientation where you should be using the interface orientation.
