CALayer，anchorPoint和层次结构
我尝试在图层层次结构中使用anchorPoint来移动图层及其子图层。不幸的是，子层没有与根层一起移动。在自定义NSView中设置我的图层层次结构，如下面的代码片段所示。
CALayer * rootLayer;
rootLayer = [[CALayer layer] retain];
rootLayer.position = CGPointMake(...);
[self.layer addSublayer:rootLayer];
subLayer = [[MapLayer layer] retain];
subLayer.position = CGPointMake(...);
[rootLayer addSublayer:baseLayer];
rootLayer.anchorPoint = CGPoint(0.7, 0.7);
rootLayer.anchorPoint = CGPoint(0.7, 0.7);
subLayer.anchorPoint = CGPoint(0.7, 0.7);
CALayer * rootLayer;
rootLayer = [[CALayer layer] retain];
rootLayer.bounds = CGRectMake(0, 0, 256, 256);
rootLayer.position = CGPointMake(...);
[self.layer addSublayer:rootLayer];
// ...
