推送通知代理方法沒有在Xcode 8.2.1中調用

Question

我在Xcode 7.3中實現了蘋果推送通知演示應用程序。它工作正常。最近我下載了Xcode 8.現在我的演示程序在Xcode 7和Xcode 8中都不起作用。委託方法沒有被調用。我不知道，出了什麼問題。 Xcode建議創建權利，我做到了。請任何人幫助我。

感謝， Vikash

推送通知，能力和BuildPhase 在AppDelegate中添加UserNotification工作框架添加委託方法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 
    } 

添加這些方法

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) { 

}
