Regardless of whether it's possible or not, I wouldn't create a dependency between a view and its view controller that way. What I'd use is a delegate: create a delegate to handle your button events, implement it in the view controller, pass it as delegate to the view, and from the view call the delegate methods in your button event handlers accordingly.
Another option is using NSNotificationCenter
- but it's more a tool to broadcast events, whereas in your case it would be a point to point notification.
