How Do I Add Social Features To App?

This question may be a little broad so of course the answers won't be as specific because of that.

I'm almost finished with developing a basic app开发者_如何学编程 but I want to add a social aspect to it. Specifically, I want a follow/followers type feed system that is seen in instagram, intonow, etc.

I looked on google but couldn't find much info on how to add this type of functionality in an app and was hoping you guys could point me in the right direction.

Take a look to Share Kit :) http://getsharekit.com

Pick one social feature first and implement them one at a time.

Do you want your app to twitter? Twitter API

Do you want to update facebook status? FaceBook API

Do you want to Foursquare? Foursquare

Once you pick one, then you can ask a question more to the point.

Take a look at Parse.

" With our user management system, you can quickly add user accounts to your app without having to code a full authentication system yourself. Our SDK provides methods to securely sign up and log in your users. This allows your users to access their account from multiple devices. "

I used Parse for Push notifications, and the SDK was very straightforward.
