I just managed to traverse recusively the AST with libclang and extract all CXCursor_ObjCImplementationDecl cursors. Is there a way to access directly their declaration ?
For the moment the only solution I found is to search one more time the AST for each CXCursor_ObjCImplementationDecl and try to find a CXCursor_ObjCInterfaceDecl having the same name. This is rather long and complex to do.
Please tell help me understand if this is the way I should extract this information.
