static void uncaughtExceptionHandler(NSException *exception) {    NSLog(@"CRASH: %@", exception);    NSLog(@"Stack Trace: %@", [exception callStackSymbols]);    // Internal error reporting}

Next, add the exception handler to your app delegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{       NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);    // Normal launch stuff}[/size]
