可以将 CGImage 添加到 CAShapeLayer 的内容属性中吗？
我有一个带有 LayerClass 覆盖的自定义视图，如下所示：
+ (Class) layerClass
{
return [CAShapeLayer class];
}
我希望能够将 CGImage 添加到内容属性，如下所示：
- (void) animateView
{
UIImage *layerImage = ...;
CAShapeLayer *layer = (CAShapeLayer *)self.layer;
layer.contents = layerImage.CGImage;
//....Do other fun animations here
}
是否有其他我需要设置的属性，或其他方法来获取形状层以呈现内容的内容动画图像？
I have a custom view with a layerClass override like:
+ (Class) layerClass
{
return [CAShapeLayer class];
}
I want to be able to add a CGImage to the contents property like so:
- (void) animateView
{
UIImage *layerImage = ...;
CAShapeLayer *layer = (CAShapeLayer *)self.layer;
layer.contents = layerImage.CGImage;
//....Do other fun animations here
}
Are there other properties I need to set, or other ways to get the shape layer to render the contents of the image for animation?

我认为不是：
CAShapeLayer几乎只是用于渲染矢量路径。您是否尝试过创建通用图层，将图像指定为其内容，并将其添加为形状图层的子图层？I would assume not:
CAShapeLayeris pretty much just used to render a vector path. Have you tried creating a generic layer, assigning your image as its contents, and adding it as a sublayer of your shape layer?
