缩放CALayer内容的大小

Question

I have a few UIImageViews inside CALayer. How do I scale them all at once? I did try setting CALayer properties like la.contentsGravity = @"kCAGravityResizeAspect"; but the images inside the layer always display the original size.

Answer 1

如果layer包含图像，则会将其缩放到65％

layer.transform = CATransform3DMakeScale(.65, .65, 1);
