推送通知代理方法没有在Xcode 8.2.1中调用

Question

我在Xcode 7.3中实现了苹果推送通知演示应用程序。它工作正常。最近我下载了Xcode 8.现在我的演示程序在Xcode 7和Xcode 8中都不起作用。委托方法没有被调用。我不知道，出了什么问题。 Xcode建议创建权利，我做到了。请任何人帮助我。

感谢， Vikash

推送通知，能力和BuildPhase 在AppDelegate中添加UserNotification工作框架添加委托方法UNUserNotificationCenterDelegate

import UserNotifications 

在didFinishingLaunching ...

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

添加这些方法

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 

    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)}) 
    print(deviceTokenString) 


} 

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { 

    print("i am not available in simulator \(error)") 

} 



@available(iOS 10.0, *) 
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping() -> Void) { 

} 

@available(iOS 10.0, *) 
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 

}
