Question

单击tableview单元格上的按钮时，我想将一些单元格数据返回到按钮动作功能

TableView代码：

var cell = self.myTable.dequeueReusableCellWithIdentifier("Cell") as! UITableViewCell
     var imgtext:AnyObject?

    if (self.SearchController.active)
    {
        cell.textLabel?.text! = self.searchArray[indexPath.row]

        cell.imageView?.image = decodedimage           

        let Acceptbutton : UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
        Acceptbutton.frame = CGRectMake(40, 60, 60, 24)
        let cellHeight: CGFloat = 44.0
        Acceptbutton.center = CGPoint(x: view.bounds.width / 1.4, y: cellHeight / 2.0)
        Acceptbutton.backgroundColor = UIColor.greenColor()
        Acceptbutton.addTarget(self, action: "AcceptClicked:", forControlEvents: UIControlEvents.TouchUpInside)
        Acceptbutton.setTitle("Accept", forState: UIControlState.Normal)
        cell.addSubview(Acceptbutton)

按钮操作：

 @IBAction func AcceptClicked(sender: AnyObject)
{
   //How can I get the cell.textlabel.text here for that specific
   // cell row that AcceptClick was triggered from?
   // I've tried sender.IndexPath but it returns nil
}

我试图将我的单元格数据传递到我的AcceptClicked函数中，这样我就可以对特定单元格进行一些操作来接受来自

首先，您不希望IBAction在函数前面，因为它不是指向Storyboard的链接。

其次，您可以使用：

func AcceptClicked(sender: AnyObject)
{
    let thisButton = sender as! UIButton
    var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
    if let indexPath = self.tableView.indexPathForRowAtPoint(position) {
        //get your cell here
        let cell = tableView.cellForRowAtIndexPath(indexPath)
    }
}

如果只想要一行：

您可以在AcceptButton.tag = indexPath.row中添加cellForRowAtIndexPath并使用：

func AcceptClicked(sender: AnyObject)
{
    let button = sender as! UIButton
    row = button.tag
}

iOS将tableview单元格信息输入按钮功能
