How we can dynamically set Facebook App ID, URL Scheme in iOS apps for integrating Facebook login?

All configuration are done in info.plist file…i am looking for a configuration is done by poor programaticall way …

i found that ,
Two functions to change App ID and Display name.
There is any function like this to change URL Scheme ???

You mean that you want to programmatically change the appID and displayname. Those are values like any other so you would have to add textfields to capture those values from the user and then have them read in that class so that they could be inserted into those calls.

but how we can change URL Scheme ?
There is no function to edit or add new URL Scheme in FBSDK…

Do you mean configuring your app to respond to a URL scheme? The Facebook SDK docs show how to do it in your app’s plist.
