我应该用什么替换CCTexture2D initWithImage

我有这个方法：

CCTexture2D *noMutableTexture = [[[CCTexture2D alloc] initWithImage:[UIImage imageNamed:@"myImage.png"]] autorelease];

我跳转到定义，发现现在唯一的方法是：

- (id) initWithData:(const void*)data pixelFormat:(CCTexture2DPixelFormat)pixelFormat pixelsWide:(NSUInteger)width pixelsHigh:(NSUInteger)height contentSize:(CGSize)size

及

我猜是后者，但我不确定如何构建CGImageRef，也不知道ccResolutionType是什么

任何帮助都将不胜感激。Thx

将纹理添加到纹理缓存时，该方法将返回纹理。从CCE的文档中：

-(CCTexture2D*) addImage: (NSString*) fileimage:

因此，在你的情况下：

CCTexture2D *noMutableTexture = [[CCTextureCache sharedTextureCache] addImage:@"myImage.png"];

是resolutionType的可能值

所以根据设备类型，iPhone或iPhone视网膜（3.5/4英寸）、iPad、iPad视网膜。分辨率类型的值各不相同

- (id) initWithCGImage:(CGImageRef)cgImage resolutionType:(ccResolutionType)resolution

您可以像这样构建CGImageRef：

UIImage *someImage = [UIImage imageNamed:@"someImage.png"];
CGImageRef someImageRef = someImage.CGImage;

你可以像这样检查你的设备类型

-(ccResolutionType)resolutionType{
    static NSInteger ret=-1;

    if (ret != -1) return ret;

    if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        if( CC_CONTENT_SCALE_FACTOR() == 2 )
            ret = kCCResolutioniPadRetinaDisplay;
        else
            ret = kCCResolutioniPad;
    }
    else
    {
        if( CC_CONTENT_SCALE_FACTOR() == 2 ){
            BOOL isWideScreenEnabled = (BOOL)(fabs((double)[UIScreen mainScreen].bounds.size.height -
                                                   (double)568) < DBL_EPSILON);

            if (isWideScreenEnabled) {
                ret = kCCResolutioniPhone5Display;
            }
            else ret = kCCResolutioniPhoneRetinaDisplay;
        }
        else
            ret = kCCResolutioniPhone;
    }

       if(ret == -1)
        ret = kCCResolutionUnknown;


    return ret;
}

你想要什么？来自CCTexture2D的CCSprite或UIImage/CGImage？？？两者均

front=[CCTexture2D addImage:@“iphone4_front.jpg”]&
front=[[CCTexture2D sharedTextureCache]添加图像：@“iphone4_front.jpg”]返回“未找到类方法，返回类型默认为id”。CCTextureCache非CCTexture2D。获取纹理的另一种方法是创建CCSprite并使用sprite的“纹理”属性。
UIImage *someImage = [UIImage imageNamed:@"someImage.png"];
CGImageRef someImageRef = someImage.CGImage;

-(ccResolutionType)resolutionType{
    static NSInteger ret=-1;

    if (ret != -1) return ret;

    if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        if( CC_CONTENT_SCALE_FACTOR() == 2 )
            ret = kCCResolutioniPadRetinaDisplay;
        else
            ret = kCCResolutioniPad;
    }
    else
    {
        if( CC_CONTENT_SCALE_FACTOR() == 2 ){
            BOOL isWideScreenEnabled = (BOOL)(fabs((double)[UIScreen mainScreen].bounds.size.height -
                                                   (double)568) < DBL_EPSILON);

            if (isWideScreenEnabled) {
                ret = kCCResolutioniPhone5Display;
            }
            else ret = kCCResolutioniPhoneRetinaDisplay;
        }
        else
            ret = kCCResolutioniPhone;
    }

       if(ret == -1)
        ret = kCCResolutionUnknown;


    return ret;
}

UIImage *someImage = [UIImage imageNamed:@"someImage.png"];
CGImageRef someImageRef = someImage.CGImage;
CCTexture2D *tex = [[CCTexture2D alloc] initWithCGImage:someImageRef resolutionType:kCCResolutionUnknown ];

CCTexture2D *tex = [[CCTexture2D alloc] initWithCGImage:someImageRef resolutionType:[self resolutionType]];
