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
MenuViewController 类:UIViewController、UITableViewDataSource、UITableViewDelegate、SetingTableViewControllerDelegate、UINavigationControllerDelegate {
@IBOutlet weak var tabelView: UITableView!
var data = ["BINATANG","BUAH","MAKANAN","SAYURAN","TUBUH","RUMAH","SEKOLAH","WARNA","ALAM","KENDARAAN","MAINAN"]
override func viewDidLoad() {
super.viewDidLoad()
self.tabelView.rowHeight = 100.0
}
函数SetingTableViewControllerDidCancel( Controller :SetingTableViewController)
{
dismissViewControllerAnimated(true, completion: nil)

dismissViewControllerAnimated(true, completion: nil)
}

super.didReceiveMemoryWarning()

as! KategoriCell
cell.imgCell.image = UIImage(named: data1[indexPath.row]+"2")

NSUserDefaults.standardUserDefaults().setInteger(indexPath.row, forKey: "kategoriIdx")
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

return height
}

最佳答案
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。
