Swift: rotate imageView around left side

Question

I have this code to rotate imageView around its axis (center of image):

transform.m34 = 1.0 / -2000.0
self.imageRevealed1.layer.transform = CATransform3DMakeRotation(CGFloat(Double.pi), 0.0, 1.0, 0.0)

But I need rotate imageView around its left side. How to do it?

Answer 1

You should modify the view anchorPoint before set the layer transform. Example, in your case, the anchorPoint should set CGPoint(x: 0, y: 0.5) , then set transform.
