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。

最近研究了下iOS8的官方文档,对这项功能进行了钻研,基本上效果已经出来。因为远程消息推送比较繁琐,需要后台支持,所以我用本地推送来代替的,基本上它们要调用的代理方法类似。长话短说,下面我就说下基本的流程:
1.创建消息上面要添加的动作(按钮的形式显示出来)
01.UIMutableUserNotificationAction
*action = [[UIMutableUserNotificationAction alloc] init];02.action.identifier
= @"action";//按钮的标示03.action.title=@"Accept";//按钮的标题04.action.activationMode
= UIUserNotificationActivationModeForeground;//当点击的时候启动程序05.//
action.authenticationRequired = YES;06.//
action.destructive = YES;07. 08.UIMutableUserNotificationAction
*action2 = [[UIMutableUserNotificationAction alloc] init]; //第二按钮09.action2.identifier
= @"action2";10.action2.title=@"Reject";11.action2.activationMode
= UIUserNotificationActivationModeBackground;//当点击的时候不启动程序,在后台处理12.action.authenticationRequired
= YES;//需要解锁才能处理,如果action.activationMode
= UIUserNotificationActivationModeForeground;则这个属性被忽略;13.action.destructive
= YES;
2.创建动作(按钮)的类别集合
1.UIMutableUserNotificationCategory
*categorys = [[UIMutableUserNotificationCategory alloc] init];2.categorys.identifier
= @"alert";//这组动作的唯一标示3.[categorys
setActions:@[action,action2] forContext:(UIUserNotificationActionContextMinimal)];1.UIUserNotificationSettings
*uns = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObjects:categorys, nil]];
4.注册推送
1.[[UIApplication
sharedApplication] registerForRemoteNotifications];2.[[UIApplication
sharedApplication] registerUserNotificationSettings:uns];
5.发起本地推送消息
01.UILocalNotification
*notification = [[UILocalNotification alloc] init];02.notification.fireDate=[NSDate
dateWithTimeIntervalSinceNow:5];03.notification.timeZone=[NSTimeZone
defaultTimeZone];04.notification.alertBody=@"测试推送的快捷回复";05.notification.category
= @"alert";06.[[UIApplication
sharedApplication] scheduleLocalNotification:notification];07. 08.//用这两个方法判断是否注册成功09.//
NSLog(@"currentUserNotificationSettings = %@",[[UIApplication sharedApplication] currentUserNotificationSettings]);10.//[[UIApplication
sharedApplication] isRegisteredForRemoteNotifications];
6.在AppDelegate.m里面对结果进行处理
01.//本地推送通知02.-(void)application:(UIApplication
*)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings03.{04.//成功注册registerUserNotificationSettings:后,回调的方法05.NSLog(@"%@",notificationSettings);06.}07. 08.-(void)application:(UIApplication
*)application didReceiveLocalNotification:(UILocalNotification *)notification09.{10.//收到本地推送消息后调用的方法11.NSLog(@"%@",notification);12.}13. 14.-(void)application:(UIApplication
*)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler15.{16.//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17.NSLog(@"%@----%@",identifier,notification);18.completionHandler();//处理完消息,最后一定要调用这个代码块19.}20. 21.//远程推送通知22.-(void)application:(UIApplication
*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken23.{24.//向APNS注册成功,收到返回的deviceToken25.}26. 27.-(void)application:(UIApplication
*)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error28.{29.//向APNS注册失败,返回错误信息error30.}31. 32.-(void)application:(UIApplication
*)application didReceiveRemoteNotification:(NSDictionary *)userInfo33.{34.//收到远程推送通知消息35.}36. 37.-(void)application:(UIApplication
*)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler38.{39.//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40.}
运行之后要按shift + command +H,让程序推到后台,或者按command+L让模拟器锁屏,才会看到效果!
如果是程序退到后台了,收到消息后下拉消息,则会出现刚才添加的两个按钮;如果是锁屏了,则出现消息后,左划就会出现刚才添加的两个按钮。
效果如下:

现在只是能让消息中显示出按钮的形式,带输入框的还在研究中,如果大家研究出来了,也谢谢能分享一下啊,大家一起提高!
