2.if you are xcode4.3 and lion,you will get this error:

 "Error: No developer directory found at /Developer. Run /usr/bin/xcode-select to update the developer directory path."

don't worry about this,go to this link:

3.after that,use the python script to add three20 to you project like this post:

(just like 1)

4.after that ,use #import "three20/Three20.h"

to start your code!!

 

thats all !

 

ps:you must be careful the "build" operation,

must build the project without using import three20 file at first!!
