ios - UITableView and UITableViewCell with dynamic height which is known only at WillDisplay -

i have uitableview cells content of variable height. if works fine autolayouted content in case content loaded (bound ui) when cell displayed (recycling, reuse, etc) chance can know real uitableviewcell height @ willdisplay of table datasource.

at point missed estimatedheight , getheightforrow stages.

please advise, how can change uitableviewcell height @ willdisplay stage

if set autolayout right, , cell should calculate own hight, doesn't matter when , change content/content height, know adapt. check top of cell content has constraint top of cells contentview, , same bottom.

estimatedheight name says, estimate. meaning should have implementation of trying calculate datasource model object height, basic implementation.

or can run application 1 time, , keep see how cell height after calculates height autolayout, less "dynamic".

if cell changes height after set, can call:

[tableview beginupdates]; [tableview endupdates]; 

and cell recalculate itself, instead of reloading hole tableview.
