How to get the angle of an image ? (IOS)

Ok, so I rotated an image by 25 degrees like this :

MyImage.layer.affineTransform = CGAffineTransformMakeRotation(25);

Now I want to rotate the image again by 25 more degrees (50 degrees in total)

So my question is, How do I rotate X more degrees an image ?

If you have any other way to rotate an image or better way please include your code.

There is no need to know the current angle! Instead of setting the affineTransform, which is only a shortcut, apply an actual 3D transform. Now you can call CATransform3DRotate, which rotates an existing transform — and thus is additive.
