ios - 应用程序在 gpus_ReturnNotPermittedKillClient 崩溃

Question

我发现新的崩溃是在 iOS 8 上运行的应用程序特有的。无法弄清楚问题是什么，也无法重现该问题。发生在 App StartUp，App 不直接调用 OpenGL ES 函数。

InitialViewController viewDidAppear 方法行 # 92 我通过以下方式从 Storyboard 中启动一个 segue:[self performSegueWithIdentifier:segueIdentifier sender:self]; where self 是 InitialViewController 类。

谁能帮我找出这个问题的根本原因。

如果应用程序试图在后台执行 OpenGL ES 命令，它将被终止。
