Custom Clear Button

Question

I want to create custom clear button on UITextField, that is to use rightView and put image there, the problem is attaching the original clear button event to that custom r

Answer 1

You can add a custom button as right view of the UITextField like this

class CustomTextField : UITextField
{
    override init(frame: CGRect) {
        super.init(frame: frame)

        let clearButton = UIButton(frame: CGRect(origin: .zero, size: CGSize(width: 15, height: 15))
        clearButton.setImage(UIImage(named: "clear.png")!, forState: UIControlState.Normal)

        self.rightView = clearButton
        clearButton.addTarget(self, action: "clearClicked:", forControlEvents: .touchUpInside)

        self.clearButtonMode = .never
        self.rightViewMode = .always
    }

    func clearClicked(sender: UIButton)
    {
        self.text = ""
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }
}
