How to update v.2.0.3 to get UIFont rendering feature from v.2.1beta3?

My purpose is to have ability to render font with UIFont as stated in http://www.cocos2d-x.org/projects/cocos2d-x/wiki/How_to_Use_Custom_TTF_Font_on_iOS.
As of now I’m using v.2.0.3, so I decided to updated with related files in creating LabelTTF and drawing string.
The following classes are what I updated from v.2.1beta3.

  • CCImage
  • CCLabelTTF
  • CCTexture2D

After that I followed the steps in the link above. Unfortunately, it still doesn’t show the correct font.
Do I miss anything? How can I update only that feature on top of v.2.0.3?

I think it works now, but for some fonts such as http://www.dafont.com/kraash.font (Kraash Black.ttf), I have to adjust increasing the height of its dimension in order to render fonts properly.
