Try to add your library path to the Library Search Path in the Build Settings of the Active Target. Follow this link: XCode Compiler Error: ld: library not found for -loauth

Assuming you have embedded the MapView project properly, check that the architectures for both the MapView project and build target match the architectures on your project.

If you have armv6 and armv7 for your project selected and the MapView project only has armv7 then you will get this error. In my case, I was building my project for both armv6 and armv7 but the MapView project was only getting built for armv7, by adding armv6 I solved the issue.
