    // Optional: automatically send uncaught exceptions to Google Analytics.
    [GAI sharedInstance].trackUncaughtExceptions = YES;
    // Optional: set Google Analytics dispatch interval to e.g. 20 seconds.
    [GAI sharedInstance].dispatchInterval = 20;
    // Optional: set debug to YES for extra debugging information.
    [GAI sharedInstance].debug = YES;
    // Create tracker instance.
    id<GAITracker> tracker = [[GAI sharedInstance] trackerWithTrackingId:@"UA-42949960-2"];

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];


    return YES;
