uitableview - Calculate custom UITableViewCell height at "indexPath" from -tableView:cellForRowAtIndexPath:? -

i adjust height of custom uitableviewcell inside custom class, , believe need use -tableview:cellforrowatindexpath: method adjust height of cell. attempting adjust height of custom cell in custom cell class, grab cell @ given index path cast it, , return height of cell this:

 - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath;  {      customuitableviewcell *cell = (customuitableviewcell *)[tableview cellforrowatindexpath:indexpath];       return cell.frame.size.height;  } 

but getting stack overflow. better way around doing this?

the table view delegate first call heightforrowatindexpath: , datasource construct cell in cellforrowatindexpath: after based on computed information.

therefore approach not work.

you need have logic computing height. (e.g. if displaying text height might dynamic , depend on amount of text - calculate nsstring method.)

if displaying few types of cells fixed heights, define these heights constants , return correct height based on same logic have in cellforrowatindexpath: decide cell use.

#define kbasiccellheight 50 #define kadvancedcellheight 100  - (cgfloat)tableview:(uitableview *)tableview         heightforrowatindexpath:(nsindexpath *)indexpath {     if (needtousebasiccellatthisindexpath) {        return kbasiccellheight;     }     return kadvancedcellheight;          }
