Objective C - getting line number or full stack trace from debugger error?

Question

Is it possible to get a line number for the source code (or anything that helps debug where the problem is) from the debugger, that shows where the problem is originating?

Answer 1

You should also consider using the NSSetUncaughtExceptionHandler. (You can save the crash log to the disk, check next startup if a new crash log was saved, attach it to an email, etc.)

put this into your didFinishLaunchingWithOptions method:

NSSetUncaughtExceptionHandler(&exceptionHandler);

and implement your exception handler:

void exceptionHandler(NSException *exception)
{        
    NSLog(@"%@",[exception name]);
    NSLog(@"%@",[exception reason]);
    NSLog(@"%@",[exception userInfo]);
    NSLog(@"%@",[exception callStackSymbols]);
    NSLog(@"%@",[exception callStackReturnAddresses]);
}
