uitableview - 使用 Swift 将 UIButton 添加到 UITableViewCell 的中心

Question

以下代码仅显示表格最后一行中的按钮。有什么想法吗？

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

    var cell:UITableViewCell = self.myTable.dequeueReusableCellWithIdentifier("cell") as UITableViewCell

    let button : UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    button.frame = CGRectMake(40, 60, 100, 24)
    button.center = self.view.center
    button.backgroundColor = UIColor.redColor()
    button.addTarget(self, action: "buttonClicked:", forControlEvents:
    UIControlEvents.TouchUpInside)
    button.setTitle("Click Me !", forState: UIControlState.Normal)
    cell.addSubview(button
 }
 return cell
 }

Jawwad 的建议解决了这个问题。这里的文档是整个工作功能:

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

        var cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell  

        let button : UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
        button.frame = CGRectMake(40, 60, 100, 24)
        let cellHeight: CGFloat = 44.0
        button.center = CGPoint(x: view.bounds.width / 2.0, y: cellHeight / 2.0)
        button.backgroundColor = UIColor.redColor()
        button.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside)
        button.setTitle("Click Me !", forState: UIControlState.Normal)

        cell.addSubview(button)

        return cell;   
}
