Question

我的应用中有一个错误导致它在iOS 7.1上随机崩溃。

我将相关的崩溃文件从iTunes Connect导入Xcode Organizer＆gt;库＆gt;设备日志，它给了我这个输出：

Exception Type:  EXC_CRASH (SIGSEGV)
    Exception Codes: 0x0000000000000000, 0x0000000000000000

我不知道如何使用它。我怎么理解这个？

从外观上看，你似乎试图写入一个你不应该写入的内存空间。尝试打开异常断点，然后重新创建导致崩溃的事件。但是因为这是SIGSEGV而不是SIGABRT可能不起作用。实际上看一下线程0。它也试图提出异常，但不能及时做到。

在做了一些研究后，看起来好像你在后台进行Open GL绘图，很可能是在你不知情的情况下。确保在移动到后台之前停止所有动画。要停止Open GL动画，我认为您可以尝试调用

glFinish()或[[CCDirector sharedDirector] pause]

停止动画并将这些动画放入applicationWillResignActive下的应用代理中，或将这些动画放入您自己的班级，并通过执行以下操作来监听辞职中的更改：

[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil];
