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.)
