推荐答案
您也可以打开例外断点。在XCode 4中单击项目并选择断点选项卡。该选项卡的底部是| + | - |搜索栏。选择+项目和添加Exeception断点。您可以将其留在全部或选择Objective-C。这样你就可以在调试器中打破，看看是什么原因导致的。
You can also turn on Exception breakpoints. In XCode 4 click your project and choose the breakpoints tab. At the bottom of that tab is | + | - | search bar. Choose the + item and "Add Exeception Breakpoint". You can leave it at All or choose Objective-C. This way you will break in the debugger and be able to see what caused the exeception.
