Scale an UIView except one of its subview

Question

I'm scaling an UIView this way:

myView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);

and the view is scaled well, but I want one of its subview to remain unscaled, i.e fullscreen. How to achieve this?

Answer 1

The only way is to add additional scaling for specific subview

myView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
specific.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1./0.9, 1./0.9);

probably you will also need to add

myView.clipsToBounds = NO;

Answer 2

I was able to get Avt's answer to work by using CGAffineTransformInvert:

myView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9)
subView.transform = CGAffineTransformInvert(myView.transform)
