iOS rotate UIImageView around a given point

[Tex-Twil]

Hello,
I have a UIImageView that I rotate around its center:

imageHorizon.transform = CGAffineTransformRotate(imageHorizon.transform, angleToRotate*(CGFloat)(M_PI/180));

but I would like to rotate it around the center of its superview. Is this possible ?

thanks,
Tex

From this thread it looks like it might be possible to do what you need:

I tried using CGAffineTransformRotate in an OpenGL game-like application and it was too slow, but the speed may not affect your app.

I found a easier solution which is putting the image in a view and rotating the view (around its center). I can move the image within the uiview and it will rotate all the time around the center of the view.
