Image Bouncing while doing interface orientation

Question

I am having paging in my application. Each page having Image. during the orientation i am changing the frame according to the landscape and portrait orientation. but image is bouncing. It should not bounce and want to set smoothly.

please let us know what can i do.

I am changing the frame in

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

Here are some code.

 - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
    {
        if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
        {
            [self performSelector:@selector(setLandscapeOrientationFrame) withObject:nil afterDelay:(duration/2)];
        }
        else
        {
            [self performSelector:@selector(setPortraitOrientationFrame) withObject:nil afterDelay:(duration/2)];
        }

    }

And in "setPortraitOrientationFrame" and "setLandscapeOrientationFrame" I am changing frame.

If you are working iOS6, you can use autolayout. The reason may be because you have used delay. If you use the code that follows, it may work.

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
 {

     if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
     {
         [self setLandscapeOrientationFrame];
     }
     else
     {
         [self setPortraitOrientationFrame];
     }

}
