简单的 Sprite Kit 场景设置出错 [英] Simple Sprite Kit Scene setup going wrong

问题描述

我正在尝试设置一个简单的 Sprite Kit 设置.我所做的只是从空应用程序"重新创建默认的 xCode 模板Sprite Kit Game".

I'm trying to set up a simple Sprite Kit setup. All I'm doing is re-creating the default xCode template 'Sprite Kit Game' from an 'Empty Application'.

它一直在 skView.showsFPS = YES; 行崩溃.我无法解释.你可以吗?谢谢！

It keeps crashing on the skView.showsFPS = YES; line. Which I can't explain. Can you? Thanks!

一些代码:

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions
{
  self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
  MenuController *menuController = [[MenuController alloc] init];
  self.window.rootViewController = menuController;
  [self.window makeKeyAndVisible];
  return YES;
}

MenuController.m

- (void)viewDidLoad
{
  [super viewDidLoad];

  SKView *skView = (SKView *)self.view;
  skView.showsFPS = YES;
  skView.showsNodeCount = YES;

  MultiplayerView *gameView = [MultiplayerView sceneWithSize:skView.bounds.size];
  gameView.scaleMode = SKSceneScaleModeAspectFill;

  [skView presentScene:gameView];
}

当我启动它时，出现以下错误:

When I launch this, the following error occurs:

2013-11-10 13:08:01.605 ByS[9419:70b] -[UIView setShowsFPS:]: unrecognized selector sent to instance 0x10c00bc60
2013-11-10 13:08:01.608 ByS[9419:70b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setShowsFPS:]: unrecognized selector sent to instance 0x10c00bc60'

推荐答案

在界面生成器中，将窗口视图的类更改为 SKView.将 UIView 类型转换为 SKView 不会做任何事情，除非 UIView 之前是通过转换 SKView 获得的.

In the interface builder, change the class of the window's view to SKView. Type-casting a UIView into SKView won't do anything unless the UIView was previously obtained by casting a SKView.
