iOS multiple twitter accounts without using phone settings



I’m currently working on a project to allow people to manage several social networks profiles in one place and I’m facing a problem when it comes to manage the profiles of the users.

What I want to do is to have my own database of users and have them to log in with that account so they can associate different profiles from different social networks to that account (instead of using the settings of the phone, like for twitter or facebook) the reason for this is because I want to be able to limit the amount of profiles a user can associated to the account per social network.

Question: How can I manage several twitter profiles without having them on the device settings?

Thanks for all the help and Happy Holidays!
