xcode - 快速在页脚表格 View 中添加按钮

Question

我想在表格页脚中添加一个按钮。我已经编写了这段代码，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(class)tableView

导入 UIKit

导入 GoogleMobileAds

我已经测试了你的代码，它工作正常，但如果它不适合你，那么还有另一种方法可以转到 Storyboard中的 ViewController，然后添加一个新的 View 来打击你的单元格，如下所示:

之后，您可以使用此代码连接该按钮的操作:

@IBAction func btn(sender: AnyObject) {

    println("Working")
}

检查 THIS示例代码。这会很好用。

HERE是包含您的代码的示例项目。
