iOS 10 静默推送通知不会触发后台应用程序 [英] iOS 10 silent push notification not triggering backgrounded app

问题描述

我有一个应用程序，我试图在其中接收和处理 SILENT 推送通知.

I have an app in which I'm trying to receive and handle SILENT push notifications.

我注册 APNs 如下:

I'm registering for APNs as follows:

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

实施:

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
}

应用有 UIBackgroundModes fetch 和 remote-notification

APN 内容如下:

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

当应用在前台时，userNotificationCenter(centre:withCompletionHandler:willPresentNotification) 在收到通知时被触发，但当应用在后台时，什么也没有发生.

When the app is in the foreground, userNotificationCenter(centre:withCompletionHandler:willPresentNotification) is fired when the notification is received, but when the app is backgrounded, nothing happens.

我可以看到通过更改徽章编号收到了 APN，但在应用程序中没有触发任何内容.

I can see the APN is received by changing the badge number, but nothing is triggered in app.

我错过了什么?

(也在 Apple 开发论坛上提问)

推荐答案

方法

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

当用户点击通知或在 Apple Watch 上查看通知时调用:

called when user taps on notification or check it on Apple Watch:

调用以让您的应用知道用户为给定通知选择了哪个操作.

Called to let your app know which action was selected by the user for a given notification.

你需要实现旧的方法

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

}
