我在一个NSObject类中创建了一个UIbutton,它控制着一个UIViewController类中的游戏。在游戏的大部分时间里,按钮都能正常工作,但在某个特定的时刻,我希望按钮进行淡入/淡出动画效果。一旦淡入/淡出动画开始播放,该按钮就不再具有交互功能。尽管我设置了.AllowUserInteraction选项,但仍然没有成功。我对此感到困惑,请帮忙解决!
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
}
.clear
的背景颜色,同时将按钮的 alpha 设置为 1。 - Knight0fDragon
