How can I locate the line causing a crash in Xcode4.2 with iOS5?

Question

When I use Xcode4.1 with iOS4, it works fine. But when I use Xcode4.2 with iOS5, it locates at the main method. So I don't know where in the program caused the crash.

Answer 1

You can set a breakpoint for all exceptoins

Command+6
Click + on the bottom left
Add Exception Breakpoint
Click Done

I am not sure why they changed the old behavior.
