Ios 如何在游戏场景中从ViewController调用方法
我的viewController中有一个自定义segue的方法,如下所示:Ios 如何在游戏场景中从ViewController调用方法,ios,swift,uiviewcontroller,sprite-kit,skscene,Ios,Swift,Uiviewcontroller,Sprite Kit,Skscene,我的viewController中有一个自定义segue的方法,如下所示: func gameOver() { performSegueWithIdentifier("GameOver", sender: nil) } @objc protocol GameOverDelegate { func gameOverDelegateFunc() } gamescene_delegate?.gameOverDelegateFunc() 我在GameSecene.swift中这样调用该
func gameOver() {
performSegueWithIdentifier("GameOver", sender: nil)
}
@objc protocol GameOverDelegate {
func gameOverDelegateFunc()
}
gamescene_delegate?.gameOverDelegateFunc()
我在GameSecene.swift中这样调用该方法:
GameViewController().gameOver()
我仔细检查了赛格的名字,它是正确的。每当我在GameSecene.swift文件中调用它时,我都会收到SIGABRT消息,我不知道为什么。我尝试只使用println()消息调用该函数,结果成功了
如果您能提供任何关于为什么会发生这种情况以及如何在GameScene.swift文件中成功调用该方法的建议,我们将不胜感激
谢谢

libc++abi.dylib:以NSException类型的未捕获异常终止
它说没有segue id。带有“GameEnd”,但有一个,如果在viewcontroller上使用它就可以了。这不起作用的原因是您正在创建一个新的
GameViewController
实例,然后您正在调用gameOver
。您真正想做的是引用现有的GameViewController
有几种方法可以做到这一点,我给你举个例子
将viewController属性添加到游戏场景类中
class GameScene {
// we need to make sure to set this when we create our GameScene
var viewController: GameViewController!
// somewhere in GameScene
self.viewController.gameOver()
在GameViewController文件中
// after GameScene is instantiated
gameScene.viewController = self
现在我们有了对viewController的引用,让我们在游戏场景类中使用它
class GameScene {
// we need to make sure to set this when we create our GameScene
var viewController: GameViewController!
// somewhere in GameScene
self.viewController.gameOver()
我没有足够的代表来回复您的上一条评论,但如果您仍然收到该错误,那是因为您尚未在Interface Builder中为该段指定名称(或标识符) 在Interface Builder中单击并拖动以在视图控制器之间绘制分段时,可以通过分段线中心显示的圆圈图标选择每个过渡,并为其指定一个“标识符”。然后,当您调用
performsguewithidentifier
时,它应该可以工作
这是圆形图标的外观,取决于segue的类型:
如果你有点不确定分段,请查看或 我不知道这是否仍然相关,但我想为您介绍一个解决此问题的方法 正如您在这里看到的,我不久前遇到了完全相同的问题,我使用协议解决了这个问题 问题是,您只能在GameViewController类中调用“performsgueWithIdentifier(“GameOver”,sender:nil)”,但您希望从游戏场景中执行它 因此,您可以在游戏场景中创建如下协议:
func gameOver() {
performSegueWithIdentifier("GameOver", sender: nil)
}
@objc protocol GameOverDelegate {
func gameOverDelegateFunc()
}
gamescene_delegate?.gameOverDelegateFunc()
以及游戏场景中代理的变量:
var gamescene_delegate : GameOverDelegate?
在GameViewController类中,必须在类定义中添加委托
class GameViewController: UIViewController, GameOverDelegate {
...
}
并将GameViewController的viewDidLoad函数中的场景代理设置为self:
scene.gamescene_delegate = self
最后一步是在GameViewController中实现gameOverDelegateFunc()函数:
func gameOverDelegateFunc() {
self.performSegueWithIdentifier("GameOver", sender: nil)
}
这就是你要做的一切
每当你想在游戏场景中执行此步骤时,你只需通过代理调用函数,如下所示:
func gameOver() {
performSegueWithIdentifier("GameOver", sender: nil)
}
@objc protocol GameOverDelegate {
func gameOverDelegateFunc()
}
gamescene_delegate?.gameOverDelegateFunc()
我希望一切都很清楚我能帮上忙
问候,,
菲尔我已经通过创建协议完成了, 我有3个游戏场景(GameSecene、GamePlaySecene、GameEndScene)和一个游戏控制器(GameViewController) 首先创建游戏协议
protocol GameDelegate {
func gameOver()
}
在GameViewController中实现协议
class GameViewController: UIViewController, GameDelegate {
override func viewDidLoad() {
super.viewDidLoad()
let scene = GameScene(size: skView.bounds.size)
scene.scaleMode = .AspectFill
scene.delegate = self
}
// MARK: Game Delegate
func gameOver() {
self.performSegueWithIdentifier("yoursegue", sender: self)
}
}
在游戏场景类中放置委托属性
class GameScene: SKScene {
var delegate: GameDelegate?
// call GamePlayScene and put delegate property
func redirectToPlay() {
let transition = SKTransition.pushWithDirection(SKTransitionDirection.Left, duration: 1.0)
let menuScene = GamePlayScene(size: size)
menuScene.delegate = self.delegate
self.view?.presentScene(menuScene, transition: transition)
}
}
在游戏场景中加入协议
class GamePlayScene: SKScene {
var delegate: GameDelegate?
// call GameEndScene and put delegate property
func gameScore() {
let transition = SKTransition.pushWithDirection(SKTransitionDirection.Left, duration: 1.0)
let menuScene = GameEndScene(size: size)
menuScene.delegate = self.delegate
self.view?.presentScene(menuScene, transition: transition)
}
}
最后,放置委托属性并调用gameOver函数
class GameEndScene: SKScene {
var delegate: GameDelegate?
init(size: CGSize) {
// call gameOver function
self.delegate?.gameOver()
}
}
希望这项工作能对你有所帮助
