本文详细介绍了iOS8中通知中心的新特性，包括直接在通知中心进行互动操作、创建自定义通知动作、不同类型的推送实现方式等。通过示例代码展示了如何实现本地、远程及地理位置推送。

iOS8拥有了全新的通知中心，有全新的通知机制。当屏幕顶部收到推送时只需要往下拉，就能看到快速操作界面，并不需要进入该应用才能操作。在锁屏界面，对于推送项目也可以快速处理。基本上就是让用户尽量在不离开当前页面的前提下处理推送信息，再次提高处理效率。

能够进行直接互动的短信、邮件、日历、提醒，第三方应用，可以让你不用进入程序就能进行快捷操作，并专注于手中正在做的事情。

在通知横幅快速回复信息，不用进入短信程序；
可直接拒绝或接受邮件邀请；
可对提醒进行标记为完成或推迟；
当第三方应用更新接口后便可直接对应用进行快速操作。

用户推送：

    //1.创建消息上面要添加的动作(按钮的形式显示出来)
        let firstAction: UIMutableUserNotificationAction = UIMutableUserNotificationAction()
        firstAction.identifier = "action";//按钮的标示
        firstAction.title = "Accept";//按钮的标题
        firstAction.activationMode = UIUserNotificationActivationMode.Foreground;//当点击的时候启动程序
        //    firstAction.authenticationRequired = true;
        //    firstAction.destructive = true;
        
        let secondAction: UIMutableUserNotificationAction = UIMutableUserNotificationAction()
        secondAction.identifier = "action2";
        secondAction.title = "Reject";
        secondAction.activationMode = UIUserNotificationActivationMode.Background;//当点击的时候不启动程序，在后台处理
        secondAction.authenticationRequired = true;//需要解锁才能处理，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略；
        secondAction.destructive = true;
        
        
        //2.创建动作(按钮)的类别集合
        let category: UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
        category.identifier = "alert"
        category.setActions([firstAction, secondAction], forContext: UIUserNotificationActionContext.Minimal)
        
        //3.创建UIUserNotificationSettings，并设置消息的显示类类型
        let uns: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: (UIUserNotificationType.Alert|UIUserNotificationType.Badge|UIUserNotificationType.Sound), categories: NSSet(object: category))
        
        //4.注册推送
        application.registerUserNotificationSettings(uns)


///////////////////////////////////////////////////////////////////
//    //5.发起本地推送消息

        UIApplication.sharedApplication().cancelAllLocalNotifications()
        let notification = UILocalNotification()
        
        let timeIntervalSinceNow = Double(seconds)
        notification.fireDate = NSDate(timeIntervalSinceNow:timeIntervalSinceNow);
        notification.soundName = UILocalNotificationDefaultSoundName;
        notification.timeZone = NSTimeZone.systemTimeZone();
        notification.alertBody = "计时完成！！！";
         notification.category = "alert";
        notification.userInfo = ["info":"开饭啦"]
        
        UIApplication.sharedApplication().scheduleLocalNotification(notification);

远程推送：

UserRequires call to registerUserNotificationSettings:• SilentInfo.plist UIBackgroundModes array contains remote-notification• Can use both(一、用户需要调用注册用户推送registerUserNotificationSettings;二、在info.plist文件中UIBackgroundModes必须包含远程通知)

离线push数据包带上特定Category字段（字段内容需要前后台一起定义，必须要保持一致），手机端收到时，就能展示上述代码对应Category设置的按钮，和响应按钮事件。

// payload example: {"aps":{"alert":"Incoming call", "sound":"default", "badge": 1, "category":"incomingCall"}}

重大修改：离线push数据包之前能带的数据最多为256字节，现在APPLE将该数值放大到2KB。这个应该是只针对IOS8的。

   [[UIApplication sharedApplication] registerForRemoteNotifications];//注册远程通知

地理位置推送：

这个推送是新的API才有的特性,必须配合CLLocation定位一起使用。（导入CoreLocation.framework）

   //注册地理位置推送
        let locationMan:CLLocationManager = CLLocationManager()
        locationMan.delegate = self
        locationMan.requestWhenInUseAuthorization()

//地理位置推送通知
func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus){
let canUseLocationNotifications = (status == CLAuthorizationStatus.AuthorizedWhenInUse);
if (canUseLocationNotifications) {
startShowLocationNotification();
}

}

func startShowLocationNotification()
{
var local2D: CLLocationCoordinate2D = CLLocationCoordinate2DMake( 123.0, 123.0)
var locNotification: UILocalNotification = UILocalNotification();
locNotification.alertBody = "你接收到了";
locNotification.regionTriggersOnce = true;
locNotification.region = CLCircularRegion(center: local2D, radius: 45, identifier: "local-identity")
UIApplication.sharedApplication().scheduleLocalNotification(locNotification);
}

如果没有开启Core Location 那么上面的didReceiveLocalNotification不会被调用

AppDelegate.m里面对通知结果进行处理：

    //本地推送通知
    func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings){
        
        //成功注册registerUserNotificationSettings:后，回调的方法
        println("%@",notificationSettings);
    }
    
    func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification){
        //收到本地推送消息后调用的方法
        println("%@",notification);
        
        
        let dict:[NSObject : AnyObject]? = notification.userInfo!;
        if ((dict) != nil) {
            let alert = UIAlertView()
            alert.title = "开饭啦"//String(dict!["info"])
            //            alert.message = "开饭啦"
            alert.addButtonWithTitle("OK")
            alert.show()
        }
        
        let region: CLRegion? = notification.region;
        if (region != nil) {
            let alert = UIAlertView()
            alert.title = "你的位置"//String(dict!["info"])
            //            alert.message = "开饭啦"
            alert.addButtonWithTitle("OK")
            alert.show()
        }
        
        
        
    }
    
    func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void){
        //在非本App界面时收到本地消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮，notification为消息内容
        println("%@----%@",identifier,notification);
        
        completionHandler();//处理完消息，最后一定要调用这个代码块
    }
    
    //远程推送通知
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData){
        //向APNS注册成功，收到返回的deviceToken
        var token: String = NSString(format: "%@", [deviceToken]);
        token = token.stringByReplacingOccurrencesOfString( "<", withString: "", options: nil, range: nil)
        token = token.stringByReplacingOccurrencesOfString( ">", withString: "", options: nil, range: nil)
        token = token.stringByReplacingOccurrencesOfString( " ", withString: "", options: nil, range: nil)
        println(token)
    }
    
    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError){
        //向APNS注册失败，返回错误信息error
    }
    
    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){
        //收到远程推送通知消息
        
    }
    
    
    func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], completionHandler: () -> Void){
        //在没有启动本App时，收到服务器推送消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮
    }

当app被kill后启动接收通知：

  let localNotify:  UILocalNotification? = launchOptions![UIApplicationLaunchOptionsLocalNotificationKey] as? UILocalNotification;
        if(localNotify != nil)
        {
        }
        
        let userInfo: AnyObject? = launchOptions![UIApplicationLaunchOptionsRemoteNotificationKey];
        if(userInfo != nil)
        {
        }
