本地通知问题

Question

一旦进程完成，我会发送本地通知，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，这些行不会被调用……我该怎么做才能让它们在后台运行？

有两种接收本地通知的方法，一种是您已经实现，在应用程序运行时调用，第二种是在应用程序运行后台调用的 didFinishLaunchingWithOptions 中，您添加了一些用于接收本地通知的代码... ..

 - (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;

}
