I created many screens in Xcode via storyboard, which successfully build and run in the iPhone simulator. Now I want to add sign-up/authentication/login/logoff, question/answer forum, star ratings system, user upload of blogs/videos, shopping cart, etc. -- for a specific niche user base. Since these things are pretty common for a social media-type app, I'm looking for best and most expeditious way to code or add plug-ins to accomplish this if possible. Thanks.
