在swift中添加页脚tableview中的按钮

Question

我想在表格页脚中添加一个按钮。我写了这段代码，但按钮不起作用。

func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
    var footerView : UIView?
    footerView = UIView(frame: CGRectMake(0, 0, tableView.frame.size.width, 50))
    footerView?.backgroundColor = UIColor.blackColor()

    let dunamicButton = UIButton.buttonWithType(UIButtonType.System) as! UIButton
    dunamicButton.backgroundColor = UIColor.greenColor()
    dunamicButton.setTitle("Button", forState: UIControlState.Normal)
    dunamicButton.frame = CGRectMake(0, 0, 100, 50)
    dunamicButton.addTarget(self, action: "buttonTouched:", forControlEvents: UIControlEvents.TouchUpInside)

    footerView?.addSubview(dunamicButton)

    return footerView
}

func buttonTouched(sender:UIButton!){
println("diklik")
}

func tableView(tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return 50.0
}

谢谢！

编辑我的类tableView

导入UIKit

导入GoogleMobileAds

类MenuViewController：UIViewController，UITableViewDataSource，UITableViewDelegate，SetingTableViewControllerDelegate，UINavigationControllerDelegate {

@IBOutlet weak var tabelView: UITableView!

 var data = ["BINATANG","BUAH","MAKANAN","SAYURAN","TUBUH","RUMAH","SEKOLAH","WARNA","ALAM","KENDARAAN","MAINAN"]

Answer 1

我已经测试了你的代码并且它工作正常但是如果它不适合你那么还有一种方法可以在storyBoard中转到你的ViewController然后添加一个新的视图来打击你的单元格，如下所示：

之后，您可以使用以下代码连接该按钮的操作：

@IBAction func btn(sender: AnyObject) {

    println("Working")
}

检查THIS示例代码。 这样可以正常工作。

HERE是带有您代码的示例项目。

只需将您的功能更改为操作：

 @IBAction func buttonTouched(sender:UIButton!){
      println("Button was clicked", sender)
 }
