苹果推送通知 – iOS 10静音推送通知不触发背景应用程序

我有一个应用程序,我正在尝试接收和处理SILENT推送通知.

我正在注册APNs如下：

UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge,.Sound,.Alert]) {(granted,error) in
    if granted {
        application.registerForRemoteNotifications()
    }
}

实现：

func userNotificationCenter(center: UNUserNotificationCenter,didReceiveNotificationResponse response: UNNotificationResponse,withCompletionHandler completionHandler: () -> Void) {
    // Handle notification
}

func userNotificationCenter(center: UNUserNotificationCenter,willPresentNotification notification: UNNotification,withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    // Handle notification
}

该应用程序具有UIBackgroundModes提取和远程通知

APN内容如下所示：

{
    "aps":{
        "content-available":1,"badge":0
    },"action":"shareDelete","shareId":633
}

当应用程序处于前台时,当收到通知时,userNotificationCenter(center：withCompletionHandler：willPresentNotification)将被触发,但是当应用程序背景时,没有任何反应.

我可以看到通过更改徽章号码收到APN,但在应用程序中没有触发任何内容.

我失踪了什么

(也在Apple开发论坛上询问)

func userNotificationCenter(center: UNUserNotificationCenter,withCompletionHandler completionHandler: () -> Void) {
    // Handle notification
}

func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable : Any],fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

}
