How to hide a button in Xcode 6?
提问by Schuey999
All I want to do is keep a button hidden until another button is pressed.
我想要做的就是隐藏一个按钮，直到按下另一个按钮。
For example, Button 1 is visible, but Button 2 isn't. When I press Button 1, I need Button 2 to appear.
例如，按钮 1 可见，但按钮 2 不可见。当我按下按钮 1 时，我需要出现按钮 2。
Also, I am programming in Xcode 6 using Swift.

// Create outlet for both the button
@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
//Set button2 hidden at start
button2.hidden = true
}
//Here is the action when you press button1 which is visible
@IBAction func button1(sender: AnyObject) {
//Make button2 Visible
button2.hidden = false
}
}
