更新到iOS 5.1后出现多个openGL错误

Question

我正在使用cocos2d v2.0 beta2开发游戏。 由于我使用iOS5.0，所以一切都很好。 昨天，我将macOS更新到了最新版本，xCode从4.2更新到了4.3.1，iPad的操作系统从5.0更新到了5.1。 现在，我正在构建我的项目，将其安装到设备上（在这里可以看到启动屏幕），但是然后我得到了：

我在设备和模拟器5.1上都没问题。 但是我将使用旧的xCode 4.2和5.0模拟器构建此代码，它运行起来很好。 我的问题在哪里？

Answer 1

问题是着色器文件。 由于某种原因，xCode丢失了它们。 我删除了它们并将它们重新添加到“复制捆绑资源”中，从iPad删除了我的应用程序，删除了所有drivedData，清理并构建了项目，并且它正常工作。
