Why does a view changes position when rotating it using CGAffineTransformMakeRotation

Question

I have the following super simple animation, I\'m basically rotating a view 2 radians from its original angle/center, it rotates fine my only misunderstanding is why does the vi

Answer 1

The "anchor" of CGAffineTransformMakeRotation is the X,Y of the view. You can try this:

CGPoint center = self.someView.center;
[UIView animateWithDuration:1.0 animations:^{
    self.someView.transform = CGAffineTransformMakeRotation( 2 );
    self.someView.center = center;
}];
