迅速制作UIButtons文本输入到一个文本框

Question

我想知道是否有可能使一个UIButton输入文本到文本框中按下

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) 
} 

时有没有一种方法，使VAR按钮输入文本到文本框（V​​AR的textBox）

在您选择的方法添加到使用addTarget

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" 
}
