localNotification问题

Question

一旦一个进程完成，我就会发送一个本地通知，它运行良好。

这是我的didReceiveLocalNotification代码：

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{

    CounterViewController *counterVC = [CounterViewController sharedInstance];
    [counterVC notificationArrived];
}

但是，当iPhone被锁定时，这些行不会被称为…我该怎么做才能让它们在后台运行？

有两种方法来接收本地通知，一种是你已经实现的，它在应用程序运行时调用；第二种是在didFinishLaunchingWithOptions中，它在你的应用程序运行时被调用，你已经添加了一些代码来接收本地通知.....

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

// Override point for customization after application launch.

// Add the view controller's view to the window and display.


application.applicationIconBadgeNumber = 0;

// Handle launching from a notification
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
    NSLog(@"Recieved Notification %@",localNotif);
}

return YES;

}
