推送通知在swift 3.0中不起作用

Question

首先我们导入UserNotifications框架 我们在AppDelegate.swift class

中初始化委托方法

if #available(iOS 10.0, *){

        UNUserNotificationCenter.current().delegate = self
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
            if (granted)
            {
                UIApplication.shared.registerForRemoteNotifications()
            }
            else{
                //Do stuff if unsuccessful...
            }
            // Enable or disable features based on authorization.
        }

    }
