推荐答案

编辑：作为下面的demianturner说明，你不再需要渲染图层，你可以（而且应该）现在使用更高级别的 [UIView drawViewHierarchyInRect：] 。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.

一个 EAGLView 只是一种视图，其基础 CAEAGLLayer 只是一种层。这意味着，用于将视图/图层转换为UIImage的标准方法将工作。 （关联的问题是UIWebview并不重要;这只是另一种观点。）

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.)
