Question

Answer 1

To post on Twitter in background use this library https://github.com/nst/STTwitter

You will need to register your app on Twitter to receive consumer key and consumer secret. After you have it just use the code represented here Accessing Twitter Direct Messages using SLRequest iOS. This code uses system Twitter credentials, user have to set these credentials in iPhone / iPad settings.

Regarding to post on Facebook: I found no wrapper for iOS which can provide possibility to post in background. I use official Facebook iOS SDK is here https://github.com/facebook/facebook-ios-sdk. But post functionality works only with user's participation.

Answer 2

For facebook make sure you have the user permission or sdk setup properly. I would recommend to go through this tutorial for details. http://m-farhan.com/2014/03/ios-facebook-sdk-tutorial/
