我已经阅读了一些如何使用UILocalNotification的指南.所以自从我第一次尝试以来,我已经尝试过并且没有成功.要在AppDelegate.m中注册通知,我使用:

        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:myTypes];
    }

    UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (locationNotification) {
        // Set icon badge number to zero
        application.applicationIconBadgeNumber = 0;
        }

        return YES;
    }

    - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
    {
    NSLog(@"notification recieved %@",notification.alertBody);
     // …
