【问题描述】：
我在 NSObject 类的代码中创建了一个 UIbutton，它控制 UIViewController 类中的游戏。该按钮在整个游戏的大部分时间都可以正常工作，但在某些时候我希望该按钮淡入/淡出。一旦淡入/淡出开始动画按钮不再是交互式的。我已经设置了 .AllowUserInteraction 选项，但仍然没有运气。我被这个难住了，所以非常感谢任何帮助！
Class GameController: NSObject {
var gameView: UIView!
var nextButton: UIButton!
func gameViewSetUp() {
// create the nextButton
let imageNextButton = UIImage(named: "rightArrow") as UIImage?
self.nextButton = UIButton(type: .Custom)
nextButton.frame = CGRectMake(ScreenWidth-100,ScreenHeight-250,60,60)
nextButton.setTitle("", forState: UIControlState.Normal)
nextButton.setImage(imageNextButton, forState: .Normal)
nextButton.contentMode = .ScaleAspectFill
nextButton.backgroundColor = UIColor.clearColor()
nextButton.layer.cornerRadius = 5.0
nextButton.layer.borderWidth = 2.5
nextButton.layer.borderColor = UIColor.clearColor().CGColor
nextButton.addTarget(self, action: "nextPressed", forControlEvents: .TouchUpInside)
nextButton.userInteractionEnabled = true
gameView.addSubview(nextButton)
func playStageX() {
nextButtonWink()
}
}
func nextButtonWink() {
UIView.animateWithDuration(1.5, delay: 0, options: [.AllowUserInteraction, .Repeat, .CurveEaseInOut, .Autoreverse],
animations: {
// self.nextButton.userInteractionEnabled = true // I tried this as well but no impact.
self.nextButton.alpha = 0
}, completion: nil)
}
class GameViewController: UIViewController {
private var controller: GameController
required init?(coder aDecoder: NSCoder) {
controller = GameController()
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
let gameView = UIView(frame: CGRectMake(0, 0, ScreenWidth, ScreenHeight))
self.view.addSubview(gameView)
controller.gameView = gameView
}
