Xcode 4.3.2 + iOS SDK 5.1异常断点不起作用

Having Followed these threads:
- Xcode always stopping at main.m after a crash - Xcode 4.2 showing the wrong line of code on error - Debugging app crashes with iOS Simulator & XCode 4 halts in main() function, not crash source

跟随这些线程: - Xcode在崩溃后总是在main.m停止 - Xcode 4.2显示错误的代码行 - 调试应用程序崩溃与iOS模拟器和XCode 4停止在main()函数,而不是崩溃源

I am still crashing at 'main' as opposed to the actual line of the crash.

我仍然在'主'崩溃,而不是崩溃的实际线。

Oddly Works on iOS 4.3 simulator!

奇怪的是在iOS 4.3模拟器上工作!

Does not work on iOS 5.1 simulator, or the iOS 5.0 simulator

不适用于iOS 5.1模拟器或iOS 5.0模拟器

I have the exception breakpoint setup and active. (Exception: All, Break: On Throw. Also have tried Break: On Catch)

我有异常断点设置和活动。 (例外:All,Break:On Throw。也尝试过Break:On Catch)

Unfortunately lldb is somewhat unstable and appears to be the cause of the crashes in your case. Switching to gdb can cause these crashes to go away.

不幸的是lldb有点不稳定,似乎是你的情况下崩溃的原因。切换到gdb可能会导致这些崩溃消失。

#2

Try this:

Breakpoints -> Add -> Add symbolic breakpoint. A new window pops up.

断点 - >添加 - >添加符号断点。弹出一个新窗口。

Type "objc_exception_throw" in symbol field and click Done.

在符号字段中键入“objc_exception_throw”,然后单击“完成”。
