IBOutlets and IBAction : Quick reference...

When I need to add an additional button and IBAction to my ViewController do I need to always add an additional IBOutlet? Or does the one reference to the IBOutlet suffice for multiple buttons and actions?

No, a UIButton element must be connected to it's own IBOutlet method and, assuming the button performs some action when pressed, an IBAction. That is, if you are not living in Xcode 2 days and are using Interface Builder. An outlet is essentially a pointer or reference connecting the button UI element in your view to it's code file. If you create more buttons, then they must be assigned a unique variable name and therefore it's own IBOutlet and action.
