在表格视图单元格按钮上查看表格视图单元格文本 [英] View tableview cell text on table view cell button

问题描述

我有一个表格视图，我在其中创建了一个标签和两个按钮.我在单击按钮时从标签中获取文本时卡住了.我创建了一个数组列表，如:

I have a table view where I have created a label and two buttons. I am stuck while getting the text from the label on button click. I have created an array list like:

let arrayList: [String] = [ "aaa" , "bbb" , "ccc"]

我想如果我点击 index[0] 上的按钮，我会得到aaa"，如果 index[2] 我会得到ccc"

I want if I click the button on index[0] I shall get "aaa" and if index[2] I shall get "ccc"

@IBOutlet weak var titleLable: UILabel!
@IBOutlet weak var infoButton: UIButton!

myCell.titleLable.text = self.arrayList[indexPath.row]
myCell.infoButton.tag = indexPath.row
myCell.infoButton.addTarget(self, action: "buttonClicked", forControlEvents: .TouchUpInside)

推荐答案

在你的表视图控制器中

let dataSource: [String] = [ "aaa" , "bbb" , "ccc"]

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

    let cell = tableView.dequeueReusableCellWithIdentifier(YourCellIdentifier, forIndexPath: indexPath) as! YourCell
    let title = dataSource[indexPath.row]
    cell.setup(withTitle: title, delegate: self)
    return cell
}

// MARK: - Your Cell Delegate
func didTapActionButton(fromCell cell: UITableViewCell) {
    if let indexPath = itemTable.indexPathForCell(cell) {
        let selectedItem = dataSource[indexPath.row]
        print(selectedItem)
    }
}

在您的表格视图单元格中

首先，定义一个协议:

protocol YourTableViewCellDelegate {
    func didTapActionButton(fromCell cell: UITableViewCell)
}

然后:

// MARK: - Properties
var delegate: YourTableViewCellDelegate?

// MARK: - @IBOutlets
@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var infoButton: UIButton!

// MARK: - @IBActions
@IBAction func buttonClicked(sender: UIButton) {
    delegate?.didTapActionButton(fromCell: self)
}

// MARK: - Public Methods
func setup(withTitle title: title, delegate: YourTableViewCellDelegate?) {
    titleLabel.text = title
    self.delegate = delegate
}
