Add MFMessageComposeViewControllerTextMessageAvailabilityDidChange notification

Question

I want to set MFMessageComposeViewControllerTextMessageAvailabilityDidChange notification to observer. I am new to swift so, i am not clear about how to do that. Please help me.

Answer 1

Swift 3.0

 let notificationCenter = NotificationCenter.default // Note that default is now a property, not a method call
 notificationCenter.addObserver(forName: Notification.Name(rawValue: MFMessageComposeViewControllerTextMessageAvailabilityDidChange),object: nil, queue: nil,using: catchNotification)

 //handle the notification fired method
 func catchNotification(notification: Notification) -> Void {

 }
