Objective-C iPhone应用程式EXC_BREAKPOINT（SIGTRAP） [英] Objective-C iPhone App EXC_BREAKPOINT (SIGTRAP)

问题描述

我最近在一个月前发布了一个应用程序，它已经过我自己，我的合作伙伴和beta测试人员的全面测试。最近用户联系我的应用程序甚至不能打开（崩溃后启动屏幕），他们有正确的操作系统，他们尝试重新安装。

I recently released an application about a month ago, it was thoroughly tested by myself, my partner, and beta testers. Recently a user contacted me about the app not even being able to open (crashes after start up screen), they have the correct OS and they tried reinstalling.

我要求提供崩溃日志，他们发送给我...

I asked for the crash log and they sent me it...

我在我的应用程序中似乎找不到问题，的问题会导致EXC_BREAKPOINT（SIGTRAP）？我假设错误在我的AppDelegate内，因为它崩溃在启动屏幕后。

I can't seem to find a problem within my app, what type of problems cause EXC_BREAKPOINT (SIGTRAP)? I'm assuming the error is within my AppDelegate since it crashes right after the start up screen.

推荐答案

我也得到了这个错误，并修复它。这个人运行OS3最可能，你使用的代码块从OS4，你需要设置一个弱链接库，以便它可以正确加载。
在您的LLVM的构建设置
-weak_library /usr/lib/libSystem.B.dylib

I've gotten this error too and fixed it. This person is running OS3 most likely and you are using a code block from OS4 you need to set a weak link on the library so that it can properly load. in your build settings for LLVM -weak_library /usr/lib/libSystem.B.dylib
