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.
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
