Standford is hosting <a href="http://www.stanford.edu/class/cs193p/cgi-bin/index.php" rel="nofollow">lecture notes and example code</a> for their iPhone Application Programming course. Lecture 15 features rotation examples and will hopefully have what you're looking for. Best of luck!

I am trying to rotate my image view upto some radians depends on the fingers touch, i m getting angle by
atan2(diffX,diffY), that is difference between old x , pos and y pos,
then
CGAffineTransform transform = CGAffineTransformMakeRotation(angle);
myImageView.transform = transform;

no error nothing, it compile well runs well but image is still there only,
not getting any rotation. can you help me where i m going wrong.
thanks a lot
