Scale the size of CALayer contents
提问by Registered User
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.
我在 CALayer 中有一些 UIImageViews。我如何一次缩放它们？我确实尝试设置 CALayer 属性，la.contentsGravity = @"kCAGravityResizeAspect";但图层内的图像始终显示原始大小。

if layercontains the image, this will scale it to 65%
如果layer包含图像，这会将其缩放到 65%
layer.transform = CATransform3DMakeScale(.65, .65, 1);
