I have a screen in landscape orientation with a UIToolbar at the bottom with 5 UIBarButtonItem's with flexible space between them. I wrote my IBAction and hooked them up. So it looks like this on the bottom: X-X-X-X-X They all work fine, but I can also trigger the action when I touch the flexible space to the left of the button. Is this a bug or something? In Interface Bulder, the flexible space is of type UIBarButtonItem. In the connections page, there is nothing in the Sent Actions.
