ios - 更改 UISwitch 时如何隐藏部分

Question

这是我的 tableView，我想隐藏“eventdays”部分我该怎么做？

希望你能帮助我。

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    // set data within item list
    self.going = ["You can go?","Whos going"]
    self.eventdays = ["Monday", "Sunday", "Wednesday"]
    self.others = ["Bread", "Butter", "Paneer"]

    // set table view delegate and data source
    self.myTableView.delegate = self
    self.myTableView.dataSource = self
    }

   override func didReceiveMemoryWarning() {
     super.didReceiveMemoryWarning()
     // Dispose of any resources that can be recreated.
   }



  // Mark: - Table view data source and delegate

  // set number of sections within table view
 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 3
 }

 // set number for rows for each setion
 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if section == 0 {
        return self.going.count
    }
    if section == 1 {
        return self.eventdays.count
    }
    if section == 2 {
        return self.others.count
    }

    return 0
 }

 // set header title for each section
 func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    if section == 0 {
        return "Can Go?"
    }
    if section == 1 {
        return "Days"
    }
    if section == 2 {
        return "Others"
    }

    return "Default Title"
}

// set cell content for each row
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    // deque reusable cell
    let cell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as UITableViewCell
    let row = indexPath.row



    //Configure the switches for swipe options
    let teilnehmenSwitch = UISwitch(frame:CGRectMake(150, 300, 0, 0));
    teilnehmenSwitch.on = false

    let eventDaySwitch = UISwitch(frame:CGRectMake(150, 300, 0, 0));
    eventDaySwitch.on = false




    switch(indexPath.section){
    case 0:
        cell.textLabel?.text = going[row]
        if row == 0 {

            cell.accessoryView = teilnehmenSwitch

        }

    case 1:
        cell.textLabel?.text = eventdays[row]
        cell.accessoryView = eventDaySwitch
    case 2:
        cell.textLabel?.text = others[row]
    default:
        cell.textLabel?.text="Others"
    }

    // return cell
    return cell
 }

我怎样才能找出哪个开关发生了变化，这样我就可以将数据保存在 DataBase 中。

提前致谢

您可以通过以下代码更改开关操作以获得更优化的重新加载解决方案

@IBAction func switchValueChange(sender: UISwitch) {
    //tableView.reloadData()
    tableView.reloadSections(NSIndexSet(index: 0), withRowAnimation: .None)
}
