Question

我正在使用Firebase管理SDK从我的节点服务器发送推送通知。但是在iOS上我只想在应用程序处于后台/终止时显示通知，而不是在前台时显示。目前它将始终显示通知。

这是我的有效载荷：

const payload = {
  data: {
    data: 'data',
    more: 'moreData',
  },
  notification: {
    title: 'Incoming Call',
    body: 'Someone is calling you',
    text: 'This is some text',
    sound: 'default',
    click_action: 'com.example.INCOMING_CALL',
  }
};
const options = {
  priority: 'high',
  time_to_live: 30,
  collapse_key: 'Video Call',
  content_available: true,
};

admin.messaging().sendToDevice(tokensList, payload, options);

它是我的有效载荷还是我必须在AppDelegate.swift中做的事情？

Answer 1

您可以使用AppDelegate，

在applicationState中实现此目的

在iOS8中：

  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {

    if !UIApplication.shared.applicationState == .active {
     // Handle your push notification here   
    }

}

在iOS10中：

import UserNotifications框架

实施UNUserNotificationCenterDelegate 方法

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {


if UIApplication.shared.applicationState == .active { // In iOS 10 if app is in foreground do nothing.
    completionHandler([])
} else { // If app is not active you can show banner, sound and badge.
    completionHandler([.alert, .badge, .sound])
}

}

感谢。

在iOS中，您决定使用AppDelegate.swift，如何处理通知。在AppDelegate中处理适当案例的通知，并在应用程序处于前台时丢弃。

在iOS 10中，要在应用终止时处理通知并从通知启动应用，请在

中处理

func application(_ application: UIApplication,  didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

 if launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] != nil {
     if  let remoteNotif = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary

    } 
 }

}

要处理前景通知，请使用此方法

 func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
     //handle notification here

 }

要处理背景通知，请使用以下方法：

 func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
     //handle notification here

 }

在前台时不显示通知
