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

问题描述

我的 iPhone 应用程序遇到了这种奇怪的行为.使用 Xcode 调试时它在设备上运行良好，但是当设备未连接到我的计算机时它在设备上运行时几乎立即崩溃.不用说，我觉得这有点令人不安，因为我不确定如何调试它.

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.

有人对发生了什么或如何调试此类问题有想法吗?

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

我在重新连接设备时查看了崩溃报告并得到以下信息:

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

控制台日志如下:

非常感谢

推荐答案

您总是可以到达应用程序崩溃的那一行.在构建文件夹上打开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

它会返回它所在的文件和行.有点用处.

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