I remember many times having apps that would pop up an alertview saying the app wanted my permission to access Twitter accounts. Is that something that has to be handled by the app itself, or does that get automatically called with
requestAccessToAccountsWithType:accountType options:nil
completion:^(BOOL granted, NSError *error)
This is in regards to iOS 6 only, not any other versions.
If you refer to the dialog
“Application” Would Like Access to Twitter Accountsit gets called automatically the first time. Further requests are ignored until the user enables access manually in Settings > Privacy > Twitter.
