應用終止時的遠程通知

Question

我是iOS和Swift的新手。我正在我的應用程序中實施遠程通知。一切正常，當應用程序處於活動狀態或在後臺。但是，當應用程序終止時，我的通知不會顯示出來。我所得到的只是通知的警報聲。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { 
    if #available(iOS 10.0, *){ 
    }else{ 
     let notification = UILocalNotification() 
     notification.alertTitle = "my Title" 
     notification.alertBody = "My Message" 
     notification.category = "customCategory" 
     notification.soundName = UILocalNotificationDefaultSoundName 
     application.scheduleLocalNotification(notification) 
    } 
} 

Answer 1

下面的AppDelegate方法將被調用當您收到通知，並應用在滅活狀態

didFinishLaunchingWithOptions 

所以，你應該從這裏妥善處理當應用程序處於滅活狀態。

下面的代碼有助於識別didFinishLaunchingWithOptions方法遠程/推或本地通知：

if let launchOpts = launchOptions as [UIApplicationLaunchOptionsKey: Any]? { 
      if let notificationPayload = launchOpts[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary { 

       //Handle push notification here 
       } 
else if let notification = (launchOpts as NSDictionary).object(forKey: "UIApplicationLaunchOptionsLocalNotificationKey") as? UILocalNotification { 
       //Handle local notification here 
       }
