UIRotationGestureRecognizer changes with CGAffineTransformMakeScale
- by user523234
A view is flipped using this:
self.transform = CGAffineTransformMakeScale(-1, 1); // self is an UIView
To rotate this view:
-(void)handleRotate:(UIRotationGestureRecognizer *)recognizer
{
recognizer.view.transform = CGAffineTransformRotate(recognizer.view.transform, recognizer.rotation);
recognizer.rotation = 0;
}
The issue is that after the view is flipped so is the rotation's direction. Any solution how to fix this?
Edit: My current solution is using a boolean and negate the recognizer.rotation value in handleRotate method. But I am still looking for the technical solution.
