尽管可以很好地处理推送通知，但我仍然相信可以立即共享完整的完整案例以简化操作：

要注册APNS的应用程序，（在AppDelegate.swift中的didFinishLaunchingWithOptions方法中包含以下代码）

iOS 9

var settings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes:UIUserNotificationType.Alert|UIUserNotificationType.Sound, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()

在IOS 10之后

引入了UserNotifications框架：

导入UserNotifications框架，并在AppDelegate.swift中添加UNUserNotificationCenterDelegate

注册APNS的申请

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in

    // If granted comes true you can enabled features based on authorization.
    guard granted else { return }

    application.registerForRemoteNotifications()
}

这将调用以下委托方法

func application(application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
//send this device token to server
}

//Called if unable to register for APNS.
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {

println(error)

}

在收到通知后，以下代表将致电：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("Recived: \(userInfo)")
   //Parsing userinfo:
   var temp : NSDictionary = userInfo
   if let info = userInfo["aps"] as? Dictionary<String, AnyObject> 
            {
                var alertMsg = info["alert"] as! String
                var alert: UIAlertView!
                alert = UIAlertView(title: "", message: alertMsg, delegate: nil, cancelButtonTitle: "OK")
                alert.show()
            }
}

要确定给定的许可，我们可以使用：

UNUserNotificationCenter.current().getNotificationSettings(){ (setttings) in

        switch setttings.soundSetting{
        case .enabled:
            print("enabled sound")

        case .disabled:
            print("not allowed notifications")

        case .notSupported:
            print("something went wrong here")
        }
    }

因此，APNS的清单：

• 创建推送通知允许的AppId
• 使用有效的证书和应用ID创建SSL证书
• 使用相同的证书创建Provisioning配置文件，并确保在添加沙箱的情况下添加设备（开发Provisioning）

注意： 如果在SSL证书后创建配置文件，那会很好。

使用代码：

• 注册应用程序以进行推送通知
• 处理didRegisterForRemoteNotificationsWithDeviceToken方法
• 设置目标>功能>后台模式>远程通知
• 处理didReceiveRemoteNotification
