从 SKScene 返回到视图控制器 [英] Go back to view controller from SKScene

问题描述

因此，当您使用 SpriteKit 模板创建项目时.你有你的视图控制器和你的 SKScene.

So when you create a project using the SpriteKit template. You have your View controller and your SKScene.

在我的视图控制器中，我使用默认提供的代码启动我的游戏并呈现场景.

From my view controller I start my game with the code given by default and present the scene.

在我的 TCAViewcontroller.m 中

In my TCAViewcontroller.m

- (IBAction)startGame:(id)sender {

    NSLog(@"Start Game triggered");
    mainPageImage.hidden = 1;
    // Configure the view.
    // Configure the view after it has been sized for the correct orientation.
    SKView *skView = (SKView *)self.view;
    if (!skView.scene) {
        skView.showsFPS = YES;
        skView.showsNodeCount = YES;

        // Create and configure the scene.
        TCAMyScene *theScene = [TCAMyScene sceneWithSize:skView.bounds.size];
        theScene.scaleMode = SKSceneScaleModeAspectFill;

        // Present the scene.
        [skView presentScene:theScene];

    }
}

当用户在游戏中失败时，我想关闭场景并回到我拥有的视图控制器.我似乎无法通过搜索找到任何返回原始视图控制器的内容，只是将游戏推到场景中.但我不想推送到另一个场景，只需关闭当前场景并返回到我的 TCAViewController.请使用代码回答以进行澄清谢谢

When the user loses in the game I would like to dismiss the scene and go back to my view controller I have. I can't seem to find anything with my searches to going back to the original view controller, just pushing to a game over scene. But I don't want to push to another scene, just dismiss the current scene and go back to my TCAViewController. Please answer using code for clarification Thanks

推荐答案

您的场景需要向您的控制器提供一条通信线路以指示已完成.例如，您可以在场景中创建委托协议和相应的属性.一个例子:

Your scene needs to offer a line of communication to your controller to indicate that is finished. You could, for example, create a delegate protocol and corresponding property in your scene. An example:

@protocol TCAMySceneDelegate;

@interface TCAMyScene : SKScene

@property (nonatomic, weak> id<TCAMySceneDelegate> delegate;

@end

@protocol TCAMySceneDelegate <NSObject>
- (void)mySceneDidFinish:(TCAMyScene *)gameScene;
@end

然后，在您的 TCAMyScene

- (void)endTheGame {
    // Other game-ending code
    [self.delegate mySceneDidFinish:self];
}

在您的视图控制器中，将自己设置为场景的代理并实现该方法:

In your view controller, set itself as the delegate for your scene and implement the method:

- (IBAction)startGame:(id)sender {
    // Other code

    TCAMyScene *theScene = [TCAMyScene sceneWithSize:skView.bounds.size];
    theScene.scaleMode = SKSceneScaleModeAspectFill;
    theScene.delegate = self;

    // Other code
}

- (void)mySceneDidFinish:(TCAMyScene *)myScene {
    // logic for dismissing the view controller
}
