Question

Is it possible to have a “floating” UITableViewCell that is always on the screen, either at the top of the list or the bottom depending on what cells are being shown?

In other words, let’s say the UITableView section has 100 cells numbered from 0 to 99. And let’s say that for some reason the one we want to highlight is number 31. (Maybe it’s a ranked list of participants in a contest, and number 31 belongs to the user.) Furthermore let’s say that we can fit 10 of these cells on the screen at once.

• if the visible range is above our highlighted cell (eg 2 to 11), then we want the highlighted cell (#31) to be overlaid at the bottom
• if the visible range includes our highlighted cell (eg 27 to 36), then we want the highlighted cell (#31) to be positioned in its natural place
• if the visible range is below our highlighted cell (eg 45 to 54), then we want the highlighted cell (#31) to be overlaid at the top

Any existing classes that do this? The table headers have similar behaviour, but not quite.

Answer 1

Apparently it’s not possible as of yet.
