I’m trying to rotate a UIImageView and keep it centered. In the image below I would like the rotated arrow (red crosshairs) center point to match up with the center point of the 0° arrow (blue crosshairs).

I have tried various anchor points but I can’t seem to get it to behave as I want.

// Rotate
self.arrowRotatedImageView.layer.anchorPoint = CGPointMake(0.5,0.5);
CGFloat angle = 45 * (M_PI/180);
self.arrowRotatedImageView.transform = CGAffineTransformMakeRotation(angle);

What am I missing? I’m reading through the Apple docs
but I haven’t been able to figure it out.

    Turns out the weird rotation issue was related to the new iOS 6 autolayout feature. Once I took some time to understand how the align constraints worked I was able to achieve the results I wanted.

    If you run into weird rotation issues and are using iOS 6 with autolayout enabled chances are your constraints need adjusting.

    The key is to vertically and horizontally center the image under rotation in it’s parent view.
