EXC_BAD_ACCESS (SIGABRT)，ios崩溃日志

Question

我的 iPhone/ipad 应用程序出现问题。它已发布在应用程序商店中，但现在似乎有一些用户在尝试启动该应用程序时遇到崩溃。有时它有助于硬重启。\n如果有人能帮我解决发生的事情，我会非常高兴。如果重要的话，该应用程序是在 unity 3d 中构建的.. Here\xc2\xb4s 我的崩溃日志：

Answer 1

EXC_BAD_ACCESS当脚本级别出现错误时抛出（例如空引用异常，但也可能是任何其他异常）。

我开发了一个游戏内开发控制台，在其中转发 Unity 和我们的脚本抛出的所有调试日志（请参阅 Unity 提供的漂亮回调http://docs.unity3d.com/Documentation/ScriptReference/Application.LogCallback.html） 。

将游戏构建为开发构建（检查构建设置），对 Unity 库进行符号链接并检查脚本调试（如果需要），您可以尝试重现导致某些用户的应用程序崩溃的步骤。这样，当发生异常时，iOS上就不会崩溃。

看一下这个 DebugConsole 实现，它可以非常快速地集成（尽管您也需要一些小的更改来转发 Unity 日志）并且可以为您完成这项工作：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，否则我们不会再发生崩溃。即使在这种情况下，您也可以追踪发生的情况。
