重新安装应用程序时的推送通知问题

Question

我在应用程序中遇到了一个奇怪的问题。在新设备上安装应用程序时推送通知工作正常，但重新安装应用程序我没有收到任何通知。是来自 API 的问题，还是在终止应用程序时必须执行某些操作？

注册设备代码：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let deviceTokenString = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
        SHARED_MGR.deviceToken = deviceTokenString
        let str = UIDevice.current.identifierForVendor!.uuidString as String
        let characterSetForDeviceID: CharacterSet = CharacterSet( charactersIn: "-" )
        deviceID = ( str as NSString )
            .trimmingCharacters( in: characterSetForDeviceID )
            .replacingOccurrences( of: " ", with: "" ) as String
        SHARED_MGR.DeviceIDStr = deviceID
        createDevice()
    }

请求授权代码：

if( UIDevice.current.systemVersion >= "10.0"){
        if #available(iOS 10.0, *) {
            let center  = UNUserNotificationCenter.current()
            center.delegate = self
            center.requestAuthorization(options: [.sound, .alert, .badge], completionHandler: { (granted, error) in
                if granted{
                    UIApplication.shared.registerForRemoteNotifications()
                } else {
                    PHPhotoLibrary.requestAuthorization { (status) in
                        print(status)
                    }
                }
            })
        } else {
            // Fallback on earlier versions
        }

    }
    else {
        let notificationTypes: UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.badge, UIUserNotificationType.sound]
        let pushNotificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: nil)
    }

请检查您的设备令牌是否在每次新启动到服务器时更新。

如果使用静态设备令牌推送通知，这可能是问题所在。

您没有收到有关新启动的推送通知。

因为设备令牌在新安装时将始终更改。
