Here's what I did:

In Your AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    //Check if its first time
    if (![[NSUserDefaults standardUserDefaults] objectForKey:@"is_first_time"]) {
        [application cancelAllLocalNotifications]; // Restart the Local Notifications list
        [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithBool:YES] forKey:@"is_first_time"];
    }

    return YES;
}

Hope it helps!
