I have a project with multiple targets each of which builds a pretty similar versions of the app but with different images assets and plists. For plists/images that's fine but I use the ShareKit and Appirater frameworks which have header files with #defines for their config. For each version I believe need to import a different version of this header file, as the config is different for each app built by each target.
So target A has SHConfig.h
and target B has a DIFFERENT SHConfig.h
I could edit the source for these frameworks to import different headers based on the target but that'd be messy when I come to upgrade the frameworks.
Is there a better way to import different header files (with the same name) based on the target?
Assuming they're in different directories, set the Header Search Paths in each target to put the correct directory first.
You may want to set it to something like $(SRCROOT)/foo:$(HEADER_SEARCH_PATHS), though I'm not sure whether that's necessary.
What I found useful was to put the Common directory name in the header search path, and then to use a different #import. My directory structure was Common/Views/v1 and Common/Views/v2. I wanted the v1 for one target and the v2 for another.
In my case, the search path I used in Header Search Paths was:
$(SRCROOT)/../Common/
Then, I used:
#import <Views/v2/ActivityIndicator.h>
In the target that needed the second version (this finds $(SRCROOT)/../Common/Views/v2/ActivityIndicator.h).
Oddly, the other target (the first one I created) is fine without specifying the full path. I.e.,
#import "ActivityIndicator.h"
works to find $(SRCROOT)/../Common/Views/v1/ActivityIndicator.h
Following process solved the issue for me
Select specific target
Under "Build Phases" --> add "New Headers Phase" --> Expand "Headers" --> click on add(plus symbol) and --> browse to the file to be added specific for the target. (It will add file under 'project' section).
Repeat the process for other targets.
