apple-push-notifications - iOS 10 静默推送通知不会触发后台应用程序

Question

我有一个应用程序，我试图在其中接收和处理 SILENT 推送通知。

我正在注册 APNs，如下所示:

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

实现的:

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
}

该应用程序有 UIBackgroundModes fetch和 remote-notification
APN 内容如下所示:

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

当应用在前台时， userNotificationCenter(centre:withCompletionHandler:willPresentNotification)收到通知时会触发，但当应用程序处于后台时，什么也不会发生。

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。

我错过了什么？

(也在 Apple 开发论坛上问过)

Answer 1

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

您需要实现旧方法

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

}
