objective c - When will UITableView reloadData have updated the visibleCells? -

i have uitableview instance tableview displays data server.

the tableview have wait until data received, , gets call it's reloaddata method. fine, works great.

now have particular method want perform right after tableview finishes creating first set of visiblecells. example i'll call method performfancyactiononvisiblecells. seems however, reloaddata action asynchronous, can't do

[tableview reloaddata]; [self performfancyactiononvisiblecells]; 

because visiblecells still empty when second line executed, have wait bit before calling it. brings me question.

to knowledge there no delegate method tableview:didfinishreloadingdata. if i'd want call performfancyactiononvisiblecells certainty reloaddata has finished updating visiblecells property, be?

cheers,
ep.

to answer question directly, not aware of delegate callback you're looking for.

but, reloaddata call [tableview cellforrowatindexpath] on each of visable rows put call @ bottom of method.

i don't think [tableview cellforrowatindexpath] gets called every cell in table called uikit required before cell made visable (for example, when scrolling).
