ios - How long is too long in cellForRowAtIndexPath to cause UITableView scrolling flicker? -


my tableview's cellforrowatindexpath taking ~20-25ms @ times, although typically closer ~15, , causing issues.

35% of coming dequeuing cell.

60% of coming calling [cell layoutifneeded] (which solution has worked me bug/glitch in ios8 self sizing table view cells [more here: http://useyourloaf.com/blog/2014/08/07/self-sizing-table-view-cells.html]).

is ton of time in terms of screen flicker?

when scroll table view, can tad jumpy. i'm wondering if has amount of time data taking lay out, or if more auto layout issue need correct.

any ideas out there if 20-25ms inordinate amount of time, or under radar?
