add button in footer tableview in swift

Question

I want to add a button in a table footer. I have written this code but the button does not work.

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
}

Thanks!

edit my class tableView

Solution

I have tested your code and it is working fine but if it is not working for you then there is one more way to do it go to your ViewController in storyBoard then add a new view blow your cell as shown below:

After that you can connect an action of that button with this code:

@IBAction func btn(sender: AnyObject) {

    println("Working")
}

Check THIS sample code. This will work fine.

HERE is Sample project with your code.
