swift 本地通知、远程通知

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) " )

}

}

// 8.0 之前 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 ()

}

// 8.0 之后 收到远程推送通知

func application(application: UIApplication , didReceiveRemoteNotification userInfo: [ NSObject : AnyObject ], fetchCompletionHandler completionHandler: ( UIBackgroundFetchResult ) -> Void ) {

let notif = userInfo as NSDictionary

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

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

var alertView = UIAlertView (title: " 远程推送通知 " , 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 ()

}
