如何通过代码从SKScene转到UIViewController？ [英] How do I go from SKScene to UIViewController by code?

问题描述

我想要的只是当用户触摸skscene中的skspritenode时，它将转到不同的视图，如 performseguewithidentifier 。谢谢你的帮助。我可以发布代码，但它似乎是一个通用的问题所以我认为你不需要任何代码。顺便说一下，我已经想出了如何检测轻敲skspritenode。我一直在看这个很长一段时间，我很难过。请帮忙。

All I want if for when the user touches a skspritenode in the skscene, it will go to a different view like performseguewithidentifier. Thanks for any help. I can post code, but it seems like a generic question so I figured that you wouldn't need any. By the way, I already figured out how to detect the tapping the skspritenode. I have been looking at this for a long time and I am stumped. Please help.

推荐答案

您无法在SKScene中呈现viewController，因为它实际上只在SKView上呈现。您需要一种方法将消息发送到SKView的viewController，后者将呈现viewController。为此，您可以使用委托或NSNotificationCenter。

You cannot present a viewController from within a SKScene as it is actually only being rendered on a SKView. You need a way to send a message to the SKView's viewController, which in turn will present the viewController. For this, you can use delegation or NSNotificationCenter.

委派

添加遵循协议定义到您的SKScene的.h文件：

Add the following protocol definition to your SKScene's .h file:

@protocol sceneDelegate <NSObject>
-(void)showDifferentView;
@end

并在界面中声明一个委托属性：

And declare a delegate property in the interface:

@property (weak, nonatomic) id <sceneDelegate> delegate;

然后，在您想要显示共享屏幕的位置，请使用以下行：

Then, at the point where you want to present the share screen, use this line:

[self.delegate showDifferentView];

现在，在你的viewController的.h文件中，实现协议：

Now, in your viewController's .h file, implement the protocol:

@interface ViewController : UIViewController <sceneDelegate>

并且，在您的.m文件中，在呈现场景之前添加以下行：

And, in your .m file, add the following line before you present the scene:

scene.delegate = self;

然后在那里添加以下方法：

Then add the following method there:

-(void)showDifferentView
{
    [self performSegueWithIdentifier:@"whateverIdentifier"];
}

NSNotificationCenter

保持-showDifferentView方法，如上一个替代方案中所述。

Keep the -showDifferentView method as described in the previous alternative.

将viewController添加为通知的监听器，其中-viewDidLoad方法：

Add the viewController as a listener to the notification in it's -viewDidLoad method:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(showDifferentView) name:@"showDifferenView" object:nil];

然后，在要显示此viewController的场景中，使用以下行： / p>

Then, in the scene at the point where you want to show this viewController, use this line:

[[NSNotificationCenter defaultCenter] postNotificationName:@"showDifferentView" object:nil];
