迅速使UIButtons將文本輸入文本框

Question

我想知道是否可以在按下時使UIButton將文本輸入文本框

override func viewDidLoad() {
super.viewDidLoad()

var textBox = UITextField(frame: CGRectMake(x, y, w, h))
    textBox.borderStyle = UITextBorderStyle.Line
    self.view.addSubview(textBox)

var button = UIButton(frame: CGRectMake(x, y, w, h))
    button.backgroundColor = UIColor.blueColor()
    self.view.addSubview(button)
}

有沒有一種方法可以使var按鈕將文本輸入到文本框（var textBox）

Answer 1

在選擇器方法中使用addTarget添加到按鈕中

var textBox = UITextField!
var button = UIButton!
override func viewDidLoad() {
    super.viewDidLoad()
    textBox = UITextField(frame: CGRectMake(x, y, w, h))
    textBox.borderStyle = UITextBorderStyle.Line
    self.view.addSubview(textBox)
    button = UIButton(frame: CGRectMake(x, y, w, h))
    button.backgroundColor = UIColor.blueColor()
    button.addTarget(self, 
        action:#selector(buttonTapped),
        forControlEvents: UIControlEvents.TouchUpInside)
    self.view.addSubview(button)
}

func buttonTapped(object:AnyObject) {
    textBox?.text = "your text"
}
