将cocos2D文件添加到UIViewcontroller中

Question

我已经创建了一个'cocos2D'游戏，以及一些菜单等等，在“classic”'objective-C'中。所以，你可以理解，我只能创建一个项目。我已经将没有问题的cocos2d的库，但现在，当我想运行我cocos2D上文件到我的“的UIViewController”，我有一些麻烦：

#import "ViewController.h" 

@interface ViewController() 

@end 

#import "HelloWorldLayer.h" 

@implementation ViewController 

+(CCScene *) scene 
{ 
    // 'scene' is an autorelease object. 
    CCScene *scene = [CCScene node]; 

    // 'layer' is an autorelease object. 
    HelloWorldLayer *layer = [HelloWorldLayer node]; 

    // add layer as a child to scene 
    [scene addChild: layer]; 

    // return the scene 
    return scene; 
} 

- (void)viewDidLoad 
{ 
    self.view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,480)]; 

    [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. 

    CCDirector *director = [CCDirector sharedDirector]; 
    CCGLView *glView = [CCGLView viewWithFrame:CGRectMake(-100, -50, 480, 480) 
            pixelFormat:kEAGLColorFormatRGBA8 
            depthFormat:0]; 
    glView.opaque = NO; 
    [director setView:glView]; 
    [director runWithScene:[HelloWorldLayer scene]]; 

} 

- (void)didReceiveMemoryWarning 
{ 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 

@end 

正如你可以看到，我的“的UIViewController”命名视图控制器，和我的cocos2D文件HelloWorldLayer。

我已经看到，在一个cocos2D项目的Introlayer文件中，HelloWorldLayer没有初始化。我尝试做相同的代码来运行我的场景，但它不工作，给我的错误：

Assertion failure in -[HelloWorldLayer addChild:], /Users/jerry-fr/Desktop/TestCocos2DIntegration/TestCocos2DIntegration/libs/cocos2d/CCNode.m:382 

2014-01-10 23:59:50.647 TestCocos2DIntegration[30030:15203] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Argument must be non-nil' 

我怎么能解决这种错误的吗？

谢谢你的帮助。

addChild：HelloWorldLayer的无对象。设置全局异常断点（请参阅xcode帮助）并检查callstack以追溯问题。
