推荐答案

在你的页面视图控制器中，添加以下内容

In your page view controller, add following

override func viewDidLoad(){
    super.viewDidLoad()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(yourpageviewcontroller.enableSwipe(_:)), name:"enableSwipe", object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(yourpageviewcontroller.disableSwipe(_:)), name:"disableSwipe", object: nil)

}
func disableSwipe(notification: NSNotification){
    self.dataSource = nil
}

func enableSwipe(notification: NSNotification){
    self.dataSource = self
}

在您的子视图控制器中，您可以通过关注来发布通知.

In your child view controller, you can just post notification by following.

NSNotificationCenter.defaultCenter().postNotificationName("enableSwipe", object: nil)

或

NSNotificationCenter.defaultCenter().postNotificationName("disableSwipe", object: nil)
