You can create your own NSDictionary and pass as a value in userInfo to determine which UIViewController you came from and appropriately handle the situation using an if statement.

Alternatively

You can use delegates to execute an event when the back button is present and perform appropriate actions on the previous UIViewController. Personally i prefer the this approach.
