For iOS Twitter Kit looks for a URL scheme in the format twitterkit-, where consumerKey is your application’s Twitter API key, e.g. twitterkit-dwLf79lNQfsJ.
Which means every time when you have to update the key it will require resubmission of the app! However Android version of the Twitter Kit does not do the same and allows developers to use/change the dynamically.
Is there any options of not locking down the app to single consumerKey for iOS the same way Android allow?
