XCode header files scanning issue

I'm working with Xcode4 and Route-me project.

I'm creating my project and including dependencies on RouteMe like the "Embedding guide" explains (https://github.com/route-me/route-me/wiki/Embedding-Guide).

The problem is XCode4 isn't able to autocomplete RouteMe names. Momentarily in the *.h or *.m I can write "RMMa" and editor suggests me 开发者_StackOverflow中文版"RMMapView" but later it never appears again. It seems like the files scanning for later autocompleting fails.

Anybody has suffer the same issues like me?

Thanks in advance.

Try step 3 of this answer: “lexical or preprocessor issue file not found ” in Xcode 4

3 - Create a group call "Indexing headers" in your project and drag the headers to this group, DO NOT add to any targets when prompted.
