Name of iOS list element that rakes with scroll

Question

In iOS, what do you call that element that attaches to the top of the screen when you scroll past it in a list (think the single letters in the Contact List). This is driving me nuts.

Answer 1

i'm not sure this is even a full question, but the answer is 'section'. If you're table style is plain, the section title will behave like the A-Z in the iPhone contacts screen
