推送通知在前台 IOS 中不起作用

Question

当应用程序在后台运行时，推送通知工作正常，当应用程序处于前台时，主要问题会出现。我能够接收有效负载，但通知横幅中未显示通知

下面收到的有效载荷

{"data": {"fcm_options": {"image": "https://importduniya.com/dealer/particular/TrustyCane.jpg"}}, "messageId": "1591459535622805", "mutableContent": true, "notification": {"body": "Test123", "ios": {}, "title": "Test"}, "sentTime": "1591459535"}

我认为当应用程序处于前台时不会调用以下函数

//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
NSLog(@"will-present");
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}

Answer 1

你应该实现application：didReceiveRemoteNotification：fetchCompletionHandler：以及
