ld: framework not found (homemade framework)

Question

I'm trying to deploy a project on an Ipad, containing a homemade framework called "HelloUnity.framework".

When I try to deploy my project I get the following error :

ld: framework not found HelloUnity clang: error: linker command failed
with exit code 1 (use -v to see invocation)

More specific :

Ld /Users/LabInnovation/Library/Developer/Xcode/DerivedData/Unity-iPhone-akzhbmwtkcooizfaebdhmbyuhrbk/Build/Products/test.app/test normal armv7
    cd /Users/LabInnovation/IpadWii/IpadWii

And I don't know why, because my framework exist and the framework's folder is not empty. What is wrong?

Thanks,

Since iOS does not support shared libraries, you need to make sure your framework is compiling to a static library.

I'm not sure about this part, but you may have to link against the static library and not the framework (i.e, '-framework HelloUnity' may not be good even if your framework is static.)
