if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
// Device is able to send a Twitter message
}
How to handle option if device has not got Twitter or Facebook account to offer users open setting and add appropriate account? I mean that device will open setting page with Facebook/Twitter account settings automatically. Is this possible? Or I just need to show alert view and it is just one option to notify user about non logged in account.
