无论是远程推送、本地推送 都需要注册通知代码

        iOS 8 把原先一步到位的 RemoteNotification 的注册分成两部分，一部分是注册新引入的那个「UIUserNotificationSettings」，另一部分是 RemoteNotifications。

        事实上，Apple 在 iOS 8 将 RemoteNotification 和 LocalNotification 统一了起来。两种 Notifications 将统一由 UIUserNotificationSettings 来管理用户界面相关的东西：标记、声音和提醒。除了统一用户界面的通知外，UIUserNotificationSettings 还引入了 UIUserNotificationCategory，可以让用户方便的直接在 Notification 上进行一些快捷的操作（Action）。

        if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))){

            application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))

        }else{

            application.registerForRemoteNotificationTypes(.Alert | .Sound | .Badge)

        }

然后，在Appdelegate.swift 写相关远程推送、本地通知等代码

    // 收到本地通知

    func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {

        var alertView = UIAlertView(title: "系统本地通知", message: notification.alertBody, delegate: nil, cancelButtonTitle: "返回")

        alertView.show()

    }

     // 远程推送通知 注册成功

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

        println(deviceToken.description)

    }

    // 远程推送通知 注册失败

    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {

        if error.code == 3010 {

            println("Push notifications are not supported in the iOS Simulator.")

        }else{

            println("application:didFailToRegisterForRemoteNotificationsWithError: \(error)")

        }

    }

    //   收到远程推送通知

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

        let notif    = userInfo as NSDictionary

        let apsDic   = notif.objectForKey("aps") as NSDictionary

        let alertDic = apsDic.objectForKey("alert") as String

        var alertView = UIAlertView(title: "系统本地通知", message: alertDic, delegate: nil, cancelButtonTitle: "返回")

        alertView.show()

    }

    // 注册通知 alert、sound、badge （8.0之后，必须要添加下面这段代码，否则注册失败）

    func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {

        application.registerForRemoteNotifications()

    }
