EXC_BAD_ACCESS (SIGABRT)，iOS崩溃日志

我有一个关于我的iPhone/iPad应用程序的问题。它已经发布在应用商店中，但现在似乎有一些用户在尝试启动应用程序时遇到崩溃的情况。有时候通过硬重启可以解决问题。如果有人能帮我弄清楚发生了什么，我会非常高兴。该应用程序是使用Unity 3D构建的，如果有影响的话...以下是我的崩溃日志：

谢谢你！

你尝试过使用"Instruments"吗？ - Bhavin

我已经尝试了工具，但是在我的设备上无法重现崩溃。 - user2219959

这个崩溃没有被符号化。这意味着我们不知道在你的游戏中它在哪里崩溃了。请参考https://dev59.com/43M_5IYBdhLWcg3wQQld和http://kevincupp.com/2011/05/12/symbolicating-ios-crash-logs.html。 - jackslash

@jackslash 感谢回复。它实际上已经被符号化了吗？之前看起来是这样的： 9 CoreFoundation 0x324cf680 0x32438000 + 620160 现在看起来像这样： CoreFoundation 0x324cf680__CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 12 或者我错了吗？ - user2219959

ARC是自动引用计数。如果您在项目中使用ARC，编译器将为您执行所有的保留、释放和自动释放调用。在一些情况下，您需要注意内存管理，但在大多数情况下，您不会遇到任何内存泄漏或悬挂指针（可能导致问题）。 - Reinhard Männer

EXC_BAD_ACCESS是在脚本层出现问题时抛出的异常（例如空引用异常，但也可能是其他任何异常）。

我开发了一个游戏内开发控制台，可以将Unity和我们的脚本抛出的所有调试日志转发到该控制台（请参阅Unity提供的良好回调http://docs.unity3d.com/Documentation/ScriptReference/Application.LogCallback.html）。

通过将游戏构建为开发版本（检查构建设置），创建Unity库的符号链接并检查脚本调试（如果需要），您可以尝试重现导致应用程序崩溃的步骤。这样，在发生异常时，它就不会在iOS上崩溃。

看一下这个DebugConsole实现，它可以非常快速地集成（尽管您需要对Unity Logs进行一些微小的更改），并且可以为您完成工作：https://gist.github.com/darktable/1412228

在我们的开发版本中，除非我们的应用程序滥用内存，否则我们不再崩溃。即使在这种情况下，您也可以跟踪发生了什么。
