推荐答案
正如下面的 demianturner 所述，您不再需要渲染图层，您现在可以(并且应该)使用更高级别的 [UIViewdrawViewHierarchyInRect:].除此之外;这应该是一样的.
as demianturner notes below, you no longer need to render the layer, you can (and should) now use the higher-level [UIView drawViewHierarchyInRect:]. Other than that; this should work the same.
EAGLView 只是一种视图，其底层的CAEAGLLayer 只是一种层.这意味着，将视图/图层转换为 UIImage 的标准方法将工作.(链接的问题是 UIWebview 的事实并不重要；那只是另一种视图.)
An EAGLView is just a kind of view, and its underlying CAEAGLLayer is just a kind of layer. That means, that the standard approach for converting a view/layer into a UIImage will work. (The fact that the linked question is UIWebview doesn't matter; that's just yet another kind of view.)
