objective-c - 将 cocos2d 场景添加到 UIViewController

Question

我使用以下代码将 cocos2d 场景添加到 View Controller

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


    if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] )
        [CCDirector setDirectorType:CCDirectorTypeDefault];

    [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888];

    [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888];


    [[CCDirector sharedDirector] setDeviceOrientation:kCCDeviceOrientationPortrait];
    [[CCDirector sharedDirector] setAnimationInterval:1.0/60];

    [[CCDirector sharedDirector] attachInView:self.view];
    ///adding HelloWorld scene to the view...
    [[CCDirector sharedDirector] runWithScene: [HelloWorld scene]];
    [super viewDidLoad];
}

现在我需要设置 self.view 的 alpha 值....所以我做到了..

-(void)displaySharePage
{
    self.view.alpha=0;

}

但它崩溃了......不知道为什么......我收到消息......

'A Director was alloced. setDirectorType must be the first call to Director'

谁能帮忙.....提前谢谢..

attachInView 将被弃用。尝试改用 setOpenGLView。 http://www.cocos2d-iphone.org/api-ref/latest-stable/interface_c_c_director.html#a87f9460b05b18b5c7726e1bdcbfe3eca
