xCode 4.3.1 always jump to main function when having exception

问题

My XCode (v4.3.1) always jump to main:

int main(int argc, char *argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");
    [pool release];
    return retVal;
}

whenever i have an exception. What's wrong with my xCode? How can I fix this issue? Please help me!

回答1:

XCode will sometimes not stop quite where you want it when an exception is thrown. If you want to know exactly where it's thrown, you can set a breakpoint in objc_exception_throw and have it halt right at the @throw line.

As a bonus if you're using multiple projects, if you add that breakpoint once to Global Breakpoints, it will work in all projects.

There's nothing wrong with your Xcoode. Depend on types of exception, some exception will jump to main when the app crash.
