Cannot set system path to Header Search Paths in XCode iOS

Question

In short, in the iOS project I set /usr/local/include/ to Header Search Paths, then in source code I cannot include the headers in this directory. But in the Mac OS X projects anything is fine. How can I modify my setting of iOS project correctly?

In the long detail, I created a new iOS Cocoa Touch Framework project. Since I wanna include some headers of boost which was installed by Homebrew, I set the Header Search Paths in build TARGETS (not PROJECTS) as /usr/local/include/. The code #include <boost/noncopyable.hpp> cannot be compiled and the message is "boost/noncopyable.hpp file not found." But in Mac OS X projects, it can be compiled with the same code and the same settings.

Answer 1

Select the Build Settings tab, then search for public header. Double click on the Public Headers Folder Path setting and enter the following in the popup:

include/$(PROJECT_NAME)

Answer 2

Select the Build Settings tab, then search for public header. Double click on the Public Headers Folder Path setting and enter the following in the popup:

Answer 3

I found out the cause of this problem, that is, the iOS projects don't figure out the alias directory(and file?).

The boost libraries through Homebrew were installed in

/usr/local/Cellar/boost/1.57.0/include/ (dependent)

, and Homebrew create some alias directories and files in

/usr/local/include/

To include heads of boost in iOS projects, we must set the Header Search Paths as real path, and not alias path.

However until now, i cannot figure out why behaviors are different between iOS projects and Mac OS X projects. The current version of XCode is 6.4 (6E35b).
