UITableView is "loaded" delegate?

Is there a sort of delegate or implementatio开发者_如何学运维n on when the UITableView is fully loaded and displayed on the screen?

---

The data source delegate provides data to the table view for the life of the table. It works "on demand" so when the user scrolls up or down, the delegate is still there providing data. At what point would is say it's finished? When it's loaded "a screen" of data? What it's loaded all the cells?

So the short answer is "no," there is no such notification.
