当设备未连接到Xcode时崩溃应用程序 [英] Crashing app when device not connected to Xcode

问题描述

我遇到这个奇怪的行为与我的iPhone应用程序。它运行良好在设备上调试与Xcode，但是当它运行在设备上，当设备没有连接到我的电脑，它几乎立即崩溃。不用说，我觉得这有点令人不安，因为我不知道如何调试它。

I've encountered this weird behavior with my iPhone app. It runs fine on the device when being debugged with Xcode, but when it's run on the device when the device is not connected to my computer it crashes almost immediately. Needless to say, I find this a bit disconcerting since I'm not sure how to debug it.

任何人都有想法，如何进行或如何调试这种类型问题？

Anyone have ideas on what's going on or how to debug this type of problem?

当我重新连接设备并获取以下内容时，我查看了崩溃报告：

I looked in the crash report when I reconnect the device and get the following:

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x00000070
Crashed Thread:  6

Thread 6 Crashed:

，控制台日志具有以下内容：

and the console log has the following:

Sun Sep 27 19:59:50 unknown ReportCrash[455] <Notice>: Formulating crash report for process myapp[453]

非常感谢

推荐答案

你总是可以得到你的应用程序的行崩溃。打开构建文件夹上的终端并运行以下命令：

You can always get to the line of your app where it crash. Open the terminal on the build folder and run this command:

atos -arch armv6 -o myapp.app/myapp 0x000033ba

atos -arch armv6 -o myapp.app/myapp 0x000033ba

，它会返回文件和行。这是有用的。

and it will return the file and line where it was. It's somehow useful.
