iOS - How to make rotation on the center of image when orientation changed

Question

In Apple Photos App, when it is rotated from portrait to landscape. The image will rotate on its center point. However, the photo app created myself just not rotate on the center point.

The structure is like this..

When it rotates to landscape.. it will look like following

And Then I'll tile the pages(ImageScrollView) in

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

is there anyone know how to make it rotate on the center of screen?

Found the answer.. set the image frame must be done in

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;

and the view will rotate on it's center
