【问题描述】：
我正在使用 SpriteKit 制作游戏。 我有 3 个视图控制器：选择级别 vc、游戏 vc 和 win vc。 游戏结束后，我想显示 win vc，然后如果我按 win vc 上的 OK 按钮，我想关闭 win vc 和游戏 vc（从堆栈中弹出两个视图控制器）。但我不知道该怎么做，因为如果我打电话
self.dismissViewControllerAnimated(true, completion: {})
win vc（栈顶）被dismiss了，所以我不知道在哪里再次调用它来dismiss游戏vc。 有什么办法可以在不使用导航控制器的情况下解决这个问题？
这是第一个VC：（请注意我下面以“//”开头的cmets）
class SelectLevelViewController: UIViewController { // I implemented a UIButton on its storyboard, and its segue shows GameViewController
override func viewDidLoad() {
super.viewDidLoad()
}
}
这是第二个VC：
class GameViewController: UIViewController, UIPopoverPresentationControllerDelegate {
var scene: GameScene!
var stage: Stage!
var startTime = NSTimeInterval()
var timer = NSTimer()
var seconds: Double = 0
var timeStopped = false
var score = 0
@IBOutlet weak var targetLabel: UILabel!
@IBOutlet var displayTimeLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet weak var gameOverPanel: UIImageView!
@IBOutlet weak var shuffleButton: UIButton!
@IBOutlet weak var msNum: UILabel!
var mapNum = Int()
var stageNum = Int()
var tapGestureRecognizer: UITapGestureRecognizer!
override func viewDidLoad() {
super.viewDidLoad()
let skView = view as! SKView
skView.multipleTouchEnabled = false
scene = GameScene(size: skView.bounds.size)
scene.scaleMode = .AspectFill
msNum.text = "\(mapNum) - \(stageNum)"
stage = Stage(filename: "Map_0_Stage_1")
scene.stage = stage
scene.addTiles()
scene.swipeHandler = handleSwipe
gameOverPanel.hidden = true
shuffleButton.hidden = true
skView.presentScene(scene)
Sound.backgroundMusic.play()
beginGame()
}
func beginGame() {
displayTimeLabel.text = String(format: "%ld", stage.maximumTime)
score = 0
updateLabels()
stage.resetComboMultiplier()
scene.animateBeginGame() {
self.shuffleButton.hidden = false
}
shuffle()
startTiming()
}
func showWin() {
gameOverPanel.hidden = false
scene.userInteractionEnabled = false
shuffleButton.hidden = true
scene.animateGameOver() {
self.tapGestureRecognizer = UITapGestureRecognizer(target: self, action: "hideWin")
self.view.addGestureRecognizer(self.tapGestureRecognizer)
}
}
func hideWin() {
view.removeGestureRecognizer(tapGestureRecognizer)
tapGestureRecognizer = nil
gameOverPanel.hidden = true
scene.userInteractionEnabled = true
self.performSegueWithIdentifier("win", sender: self) // this segue shows WinVC but idk where to dismiss this GameVC after WinVC gets dismissed...
}
func shuffle() {...}
func startTiming() {...}
}
这是第三个 VC：
class WinVC: UIViewController {
@IBOutlet weak var awardResult: UILabel!
@IBAction func dismissVC(sender: UIButton) {
self.dismissViewControllerAnimated(true, completion: {}) // dismissing WinVC here when this button is clicked
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
【问题讨论】：
-
解除多个模式视图控制器的更通用方法是here
-
下面的大多数答案都包含动画故障（在解雇期间简要显示中间 vc）。 谢天谢地，我能够通过this simple solution 解决它。
