Switch 中 TableView 中的 UISwitch [英] UISwitch in TableView in Switch

问题描述

各位程序员好！我有一个需要帮助的挑战.我使用自定义样式单元格构建了一个表格.

Hello fellow programmers! I have a challenge I need help with. I have built a table using a Custom Style Cell.

这个单元格只有一个Label 和UISwitch.标签显示姓名，开关显示他们是否为管理员.这完美地工作.我的挑战是如何以及在何处放置代码以在更改开关时做出反应.

This cell simply has a Label and UISwitch. The label displays a name and the switch displays whether they are an Admin or not. This works perfectly. My challenge is how and where do I put code to react when the switch is changed.

因此，如果我单击开关将其从关闭更改为开启，我在哪里可以让它打印人名?如果我可以打印名称，我可以自己编写 php/sql 代码.谢谢，这是我的代码片段.

So if I click the switch to change it from off to on where can I get it to print the persons name? If I can get the name to print I can do the php/sql code myself. Thanks and here is a snippet from my code.

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(kCellIdentifier) as UITableViewCell
    let admin = self.admin[indexPath.row]

    let text1a = admin.FirstName
    let text1aa = " "

    let text1b = admin.LastName
    let text1 = text1a + text1aa + text1b
    (cell.contentView.viewWithTag(1) as UILabel).text = text1

    if admin.admin == "yes" {
        (cell.contentView.viewWithTag(2) as UISwitch).setOn(true, animated:true)

    } else if admin.admin == "no" {
        (cell.contentView.viewWithTag(2) as UISwitch).setOn(false, animated:true)
    }

    return cell
}

推荐答案

您必须在自定义表格视图单元格中设置 action 来处理 UISwitch 中的更改并对其中的更改做出反应，请参阅以下代码:

You have to set an action in your Custom Table View Cell to handle the change in your UISwitch and react to changes in it, see the following code :

class CustomTableViewCell: UITableViewCell {

     @IBOutlet weak var label: UILabel!

     @IBAction func statusChanged(sender: UISwitch) {
         self.label.text = sender.on ? "On" : "Off"
     }
}

上面的例子只是用来改变 UILabel 的关于 UISwitch 状态的文本，当然你必须根据你的要求来改变它.我希望这对您有所帮助.

The above example is just used to change the text of the UILabel regarding the state of the UISwitch, you have to change it in base your requirements of course. I hope this help you.
