Quincey Hello and thx for the reply

I need to use the a library because its a iOS project so no framework, and also because I will be reusing the code in the lib for many other apps not just this one Im making..

So right now I have the following set up:

On my Library Project:

Note: By nothing I mean empty no value
	2 Targets:
		-myLibrary :
				Library Search Paths : nothing
				Other Link Flags : nothing

				Copy Headers:  As Public : All my Headers.
		-cocos2d
		cocos2d lib was easily configured I have done it before for other UIKit apps

I compile this project without problem and it compiles.

Now I created my Final app that will use my library

I made a workspace where I put the project and the project that contains the library, both are there.
	-Added the libraries (cocos, myLib) to the project and then link them to the app.

	Header Search Path : Path to the headers of my library
	Other Link Flags : -ObjC -all_Load


Now in my app delegate I have the line

#import "IADTravelEngine.h"

...

..

IADTEDirector * dir = [IADTEDirector sharedDirector];

and I get that IADTravelEngine.h No such a file.


I dunno what I did before to make it work  (Link) and it was working until I used the NSClassDFromString then I started modifying things and now it doesnt link again. :S

Any help?

Thx

Gustavo

This doesn't work very well in Objective-C, because the language's dynamism makes it impossible in general to determine what's "referenced" at link time.
