无法获取设备令牌

Question

我需要获取设备令牌。 “允许”和“不允许”选项将提示提示弹出窗口。但是当我使用我的客户帐户时，我的设备令牌方法不会被调用。当我刚使用另一个帐户时，我的方法被调用。他们与苹果开发者帐户或其他人有任何问题。我正在尝试但没有得到适当的解决方案。

let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        let characterSet: NSCharacterSet = NSCharacterSet(charactersInString: "<>")
        let deviceTokenString: String = (deviceToken.description as NSString)
            .stringByTrimmingCharactersInSet(characterSet)
            .stringByReplacingOccurrencesOfString( " ", withString: "") as String
        NSUserDefaults.standardUserDefaults().setObject(deviceTokenString, forKey: "callBackToken")

    }
