Adding Tapku Library to iOS Project - Linker Errors

I'm building a calendar application and am trying to add the Tapku library to my app. I've followed the steps here: "https://github.com/devinross/tapkulibrary/wiki/Adding-Tapku-to-Your-Project-in-XCode-4". My project builds until the last step. When I add "-ObjC" to other linker flags I get errors when building.

I've included a screenshot with an error saying that the flag is invalid along with the linker errors.

Thanks in advance!

Solution

The problem was that my project was using both Parse and Tapku. After following the instructions here: Parse for iOS: Errors when trying to run the app I was able to get it working.
