处理本地和远程通知

用法示例：

/* Instance of your custom APNs/local notification manager */  
private var pushManager: AppleNotificationManager!

注册：

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    // Called to tell the delegate the types of notifications that can be used to get the user’s attention
    pushManager.didRegisterSettings(notificationSettings)
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    // Tells the delegate that the app successfully registered with Apple Push Notification service (APNs)
    pushManager.didRegisterDeviceToken(deviceToken)
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    // Sent to the delegate when Apple Push Notification service cannot successfully complete the registration process.
    pushManager.didFailToRegisterDeviceToken(error)
}

远程通知处理：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    // Remote notification arrived, there is data to be fetched
    // Handling it
    pushManager.handleNotification(userInfo,
                                   background: application.applicationState == .Background
    )
}

本地通知处理：

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
    pushManager.handleLocalNotification(notification, background: false)
}

处理行动（不建议使用）：

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject],
                     completionHandler: () -> Void) {
    pushManager.handleInteractiveRemoteNotification(userInfo, actionIdentifier: identifier, completion: completionHandler)
}
