问题
Newbie here, trying to add the CHDataStructures library to a calculator project I'm working on. I did as suggested in the accepted answer at Linking a static library to an iOS project in XCode 4 and have ended up with this:
Unfortunately, I get a 'CHDataStructures.h' file not found error when I try to add the header to classes in my project (Calculator.m, for example).
Any thoughts about how I can get the CHDataStructures library to be, like the Death Star, fully operational?
EDIT
Okay, here's trying both $(SRCROOT) and the absolute path. Any thoughts?
回答1:
By default, Xcode searches for headers recursively in the project's own directory. If you're using a static library, you'll need to use the lib's header files which likely reside somewhere else. There are 2 settings in an Xcode project that allow you specify additional paths to search during compilation:
User Header Search Paths
#import "SomeHeader.h"
Header Search Paths
#import <SomeHeader.h>
Depending on which style you intend to use, pick the appropriate setting, and supply the path to the header files you wish to use:
The paths can be recursive, relative to the project (using $(SRCROOT)/), or absolute. You could also use the derrived data directory if you have Xcode set up correctly.
