The following project is an XCode project showing the use of the TabBarController and separated storyboards.
This allows for more modular coding that is helpful in group development as well as loading the files.
This is a simple project which I hope can help those learning iOS programming gain some insight when
building more complicated projects.
You can find my tutorial with this project here. Understand that this is for those just learning as I made this while I was working on a project that got too big and needed to separate things out into multiple storyboards.
