解决方法
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.
