iOS Build a Simple iPhone App (iOS7) Getting Started Assign String to a Label

There appears to be an error in this challenge

The challenge calls for one to create a method to as the action for a button press. The following syntactically-correct code causes an error in the editor:

- (IBAction)buttonPressed:(id)sender 

while the following code works, incorrectly:

- (IBAction)buttonPressed

Shouldn't the method take a parameter that represents the sender of the action?

Its optional. I think when you set the IBAction you can choose to say None as parameters. Maybe the exercise is looking for a parameter less event handler. (just a thought).
