在前台不显示通知 [英] Don't show notification when in foreground

问题描述

我使用Firebase管理软件开发工具包从我的节点服务器发送推送通知。但在iOS上，我只想显示通知时，应用程序是在后台/终止，而不是在前台。

 const payload = {
 data：{
 data：'data'，
 more：'moreData'，
}，
通知：{
 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）; 
  

这是否与我的有效载荷有关，或者是我必须在AppDelegate.swift中做的事情？ 使用<$ c>可以在 AppDelegate 在iOS8中：












$ b

  func application（_ application：UIApplication，didReceiveRemoteNotification userInfo：[AnyHashable：Any]）{
 
 if！UIApplication.shared.applicationState == .active {
 //在此处理您的推送通知
 
 
 $ b code $ 
 
 
在iOS10中：  
 
 
 
 
  import UserNotifications 框架 
 
 
实现 UNUserNotificationCenterDelegate  
方法 
 
 
  func userNotificationCenter（_ center：UNUserNotificationCenter，willPresent notification：UNNotification，withCompletionHandler completionHandler ：@escaping（UNNotificationPresentationOptions） - >无效）{
 
 
如果UIApplication.shared.applicationState == .active {//在iOS 10中，如果应用程序处于前景，则什么也不做。 
 completionHandler（[]）
} else {//如果应用程序不活跃，您可以显示横幅，声音和徽章。 
 completionHandler（[。alert，.badge，.sound]）
} 
 
} 
  
 
 
 
谢谢。
 
I'm sending push notification from my node server using the Firebase admin SDK. But on iOS I only want to show the notification when the app is in the background/terminated and not when in the foreground. Currently it will always show the notification.

This is my payload:
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);
Is it something with my payload or is it something that I have to do in the AppDelegate.swift?
解决方案
You can achieve this in AppDelegate by using the applicationState,

In iOS8:
  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {

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

}
In iOS10:

import UserNotifications framework
Implement UNUserNotificationCenterDelegate
    method
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])
}

}

Thanks.
