2.0.4 CCLabelTTF在ios7下不显示的问题(转)

​

要修改框架lib目录里的 CCImage.mm，就是把浮点值取了个整，之前的浮点形导致绘制失败：

在_initWithString这个方法里把如下代码替换一下就行了：

/
        /
        // for CCLabelTTF can not show text in ios7
        /*
        unsigned char* data = new unsigned char[(int)(dim.width * dim.height * 4)];
        memset(data, 0, (int)(dim.width * dim.height * 4));
        
        // draw text
        CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();    
        CGContextRef context = CGBitmapContextCreate(data, dim.width, dim.height, 8, dim.width * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
         */
        
        const int _width  = dim.width;
        const int _height = dim.height;
        
        unsigned char* data = new unsigned char[(int)(dim.width * dim.height * 4)];
        memset(data, 0, (int)(_width * _height * 4));
        
        // draw text
        CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
        CGContextRef context =
        CGBitmapContextCreate(data, _width, _height, 8, _width * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
