How to animate UIImageView scale but keep its image unchanged?

I have a circle UIImageView with a user picture as an image.
I need to implement an animation - to make it possible to scale UIImageView down/up but keep its image unchanged.
I have tried the following code:

[UIView animateWithDuration: 2.0f animations: ^{
    self.myImageView.transform = CGAffineTransformMakeScale(0.5f, 0.5f);
}];

But it changes the image scale too. I think this is expected behavior, so I need help - how to implement such kind of animation? (Scale only UIImageView and keep image unchanged)

You should animate myImageView.frame or myImageView.bounds instead. Be sure the contentMode is set to something that does not scale the image, such as top left or center.
