Question

当我得到内存警告级别-1时，我的EAGLView开始吐出openGL错误行（502＆amp; 506）并且应用程序不会崩溃，但EAGLView变得无法响应。因为Cocos2d Director调用draw而错误是垃圾邮件。

这是内存警告回调的外观：

- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application {
    [[CCDirector sharedDirector] purgeCachedData];
}

502和506错误是什么意思，2。如果内存警告对opengl视图有任何影响，或者它是否会在我的代码中释放它不应该出现的内容？

[更新]

设法从cocos2d中获取一些详细日志：

Received memory warning. Level=1
cocos2d: deallocing <CCSprite = 002657B0 | Rect = (0.00,0.00,32.00,32.00) | tag = -1 | atlasIndex = -1>

cocos2d: deallocing <EAGLView: 0x24aee0; frame = (0 0; 1024 768); transform = [0, -1, 1, 0, 0, 0]; autoresize = RM+BM; layer = <CAEAGLLayer: 0x2492c0>>
cocos2d: deallocing <ES1Renderer = 0024D0E0 | size = 768x1024>
modifying layer that is being finalized - 0x2fab80

所以这几乎就是一切。看起来除了场景节点之外的所有东西都在消失。

至于OpenGL错误的含义，你可以参考你的OpenGL标题，它会告诉你502是GL_INVALID_OPERATION而506是GL_INVALID_FRAMEBUFFER_OPERATION。

我无法从您的问题或提供的代码中看到任何内容，但我假设您要提前释放帧缓冲区（在运行时可能不应该这样做），或者Cocos2D在您调用时释放帧缓冲区purgeCachedData（后者我有点怀疑）并且没有完全重建它（如果有的话）。您可能需要检查EAGLView的实现，看看它是否设置为在需要时处理重新创建帧缓冲区（并查看是否存在您不必要地释放帧缓冲区的地方）。

也就是说，如果您收到内存警告，您可能也希望解决这些问题的来源。
