iOS 5上的应用程序崩溃

iOS 5上的应用程序崩溃

3

我一直在我的应用程序中使用Mobclix，直到昨天我收到了来自TestFlight的崩溃报告，显示是由Mobclix引起的。我想知道是否有人能够解释这种情况或者如何防止它再次发生。此问题出现在运行iOS 5.0.1的iPhone 4s上。感谢任何意见！

抱歉，我忘记包含它了。我已将其添加到我的崩溃日志的顶部。 - Stephen Woodford

请发布createAdBannerView（LocationDetailViewController）方法的实现和相关的Mobclix代码。 - Felix

在TestFlight崩溃报告中，您只能从主线程获取堆栈跟踪。但是，实际的崩溃可能发生在另一个线程中，并由主线程处理。如果您可以使用相同的回溯重现该崩溃，则Mobclix确实存在错误。

您需要完整的崩溃报告，只有在您可以访问设备时才能获取。

您可以在此答案中找到更多有用的信息： https://dev59.com/zmw15IYBdhLWcg3wqNqM#6462751

编辑：正如我所说，真正的崩溃发生在不同的线程（线程1）中。但我无法弄清楚是什么导致了崩溃。请查看其他涉及MyApp的回溯（线程4、6和12）。

我会努力获取从设备发送的完整崩溃报告，我自己无法重现这个崩溃。 - Stephen Woodford

设备的完整崩溃日志已获取，任何帮助将不胜感激。 - Stephen Woodford

我已经尝试使用相同的回溯信息多次重现崩溃，但没有产生任何一个崩溃。我不确定接下来该怎么做。 - Stephen Woodford

崩溃线程1只有苹果框架调用，没有来自您应用的内容。如果符号化脚本可以通过Spotlight访问iOS 5.0.1符号，则这些内容将被符号化。目前看来，这个问题与Mobclix代码无关。

由于异常类型是SIGSEGV，因此在导致崩溃的崩溃线程中不会找到行号。您的代码中某个地方（任何地方都可能！）存在内存问题，导致应用程序试图访问实际上是无效的内存地址。从而导致崩溃。

由于libdispatch是崩溃线程的一部分，这可能是您使用GCD的某个地方可能是问题区域的提示。正如所说，最有可能是内存问题。

总的来说，我发现可靠地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，使其运行很长时间。重复相同的用户交互也有帮助。它很可能会崩溃，但这次是可重现的，因此您可以在旁边使用工具箱进行自动化。我曾经非常成功地使用了KIF框架。

要获取完整的崩溃报告，您可能需要查看备选崩溃报告解决方案，我在这里提及了其中之一：https://dev59.com/_2sy5IYBdhLWcg3w6iNZ#8242215
