我一直在我的应用程序中使用Mobclix并且直到昨天我收到TestFlight的崩溃报告时才遇到任何问题，该报告似乎是由Mobclix引起的。我想知道是否有人可以对这种情况有所了解，或者我是如何阻止它再次发生的。这发生在运行iOS 5.0.1的iPhone 4上。感谢您的任何意见！

答案 0 :(得分：5)
崩溃的线程1只有Apple框架调用，而您的应用程序中没有任何内容。如果符号化脚本具有可通过Spotlight访问的iOS 5.0.1符号，那么这些将符号化。到目前为止，这个问题看起来不太可能与Mobclix代码有关。
由于异常类型是SIGSEGV，因此您不会在崩溃线程中找到导致崩溃的行号。您的代码中有某处（可能在任何地方！）存在内存问题，导致应用程序尝试访问实际上无效的内存地址。因此，导致崩溃。
由于libdispatch是崩溃线程的一部分，这可能是一个提示，在您的代码中使用GCD的某个地方可能是您的问题所在。如上所述，很可能是记忆问题。
一般而言，我发现可靠查找和解决内存问题的最佳方法是使用测试框架并自动执行应用程序交互，以便运行很长时间。通过一遍又一遍地重做相同的用户交互，它还有助于自动化它。它很可能会崩溃，但这次可以重现，因此您可以将仪器放在一边自动运行。我确实使用了KIF框架并取得了巨大的成功。
要获取完整的崩溃报告，您可能需要查看其他崩溃报告解决方案，我在此处暗示：https://stackoverflow.com/a/8242215/474794
答案 1 :(得分：0)
您只能从TestFlight崩溃报告中的主线程获取堆栈跟踪。然而，可能真正的崩溃发生在另一个线程中，主线程处理它。如果您可以使用相同的回溯重现该崩溃，那么Mobclix中确实存在一个错误。
当您有权访问设备时，您将需要完整的崩溃报告。
您可以在此答案中找到更多有用的信息： https://stackoverflow.com/a/6462751/550177
编辑：正如我所说，真正的崩溃是在一个不同的线程（线程1）。但我无法弄清楚导致坠机的原因。查看涉及 MyApp 的其他回溯（线程4,6和12）。
