如何隐藏Xcode 6中的按钮？

Question

我想要做的就是隐藏一个按钮,直到按下另一个按钮.

例如,按钮1可见,但按钮2不可见.当我按下按钮1时,我需要按钮2出现.

另外,我使用Swift在Xcode 6中编程.

提前致谢!

Answer 1

在Swift中隐藏按钮的示例代码:

import UIKit

class ViewController: UIViewController {

// 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
    }

}

可能这可以帮到你.
