Plenty of applications seem to do this. For example, go to Apple's mail application and press the "reply" button on the toolbar. You'll get a menu with buttons that say "Reply", "Reply All", "Forward" and "Cancel" that will scroll up from the bottom.
The way I figure I could do this is to create a short view in IB with the buttons I want, present it modally, and right a view controller to handle the buttons.
It seems like this is so common that there must be an easier way to do it (like how easy it is to add to the toolbar and navigation bar).
Is there some widget or shortcut that I am missing?
