  • 2.0.4 CCLabelTTF在ios7下不显示的问题

    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:

     1  /////////////////////////////////////////////////////////
     2         /////////////////////////////////////////////////////////
     3         // for CCLabelTTF can not show text in ios7
     4         /*
     5         unsigned char* data = new unsigned char[(int)(dim.width * dim.height * 4)];
     6         memset(data, 0, (int)(dim.width * dim.height * 4));
     7         
     8         // draw text
     9         CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();    
    10         CGContextRef context = CGBitmapContextCreate(data, dim.width, dim.height, 8, dim.width * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
    11          */
    12         
    13         const int _width  = dim.width;
    14         const int _height = dim.height;
    15         
    16         unsigned char* data = new unsigned char[(int)(dim.width * dim.height * 4)];
    17         memset(data, 0, (int)(_width * _height * 4));
    18         
    19         // draw text
    20         CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    21         CGContextRef context =
    22         CGBitmapContextCreate(data, _width, _height, 8, _width * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
    23         
    24         /////////////////////////////////////////////////////////
    25         /////////////////////////////////////////////////////////
