what is this iPhone UI technique called?

Question

In iPhone UI terms, what's the name of the effect that causes additional options to appear when you tap-and-hold an element?

For example, when you hold down the "e" keyboard key for a moment, causing the additional accent mark buttons to appear.

Is there an established approach to implementing this effect, or should I code it up from scratch?

Answer 1

I would call that hover...but I don't know if there's a standard or built in way to do it (sorry). Or for an OS9 throw back you could call it click and hold.

Answer 2

Umm… maybe an UICallout view, but those are forbidden. As seen in maps when you select a location.

Answer 3

I've seen it referred as touch and hold. About implementing it, I'm thinking about a no-repeat NSTimer that fires a certain amount of time from your touchDown event, and invalidates on touchUpInside or touchUpOutside, in case you stop the touch before the amount of time elapses.
