When you drag the ZipArchive folder into your project, you have to choose "Create groups for any added folders" and not "Create folder references for any added folders." If you choose the latter, you'll get the Undefined Symbol error from the linker.

Then just drag & drop ZipArchive folder in to xCode "Classes".

Then add framework libz.1.2.3.dylib.

That's it. My code get compile without any issue.

i have used this library before, you need to compile the library in Xcode static library then later included it in your project, see the following link it will help you a lot.

You say you have added the ZipArchive folder to the project. From your description, it seems that the header file ZipArchive.h is found during the compilation of the project, but it does not compile the ZipArchive.mm file, which contains the ZipArchive class.

The file extension .mm seems strange to me. It might be the reason the file in't compiled. Try to rename it to ZipArchive.m and try again.

ZipArchive is not in libz.dylib. Where is ZipArchive supposed to come from? It's not getting compiled or linked to your app.
