ios - How to resize UITableViewCell to fit its content? -

i have uitableview multiple reusable tableviewcells. in 1 cell have uitextview, resizes fit content. "just" have resize contentview of tableviewcell, can read while text. tried:

cell2.contentview.bounds.size.height = cell2.discriptiontextview.bounds.size.height;  

or:

cell2.contentview.frame = cgrectmake(0, cell2.discriptiontextview.bounds.origin.y,      cell2.discriptiontextview.bounds.size.width,      cell2.discriptiontextview.bounds.size.height);  

in method:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath  *)indexpath {}   

but won't work.

does know how this?

new code:

    @implementation appdetail      cgfloat height;     …      - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath     {…      cell2.textview.text = self.text;             [cell2.textview sizetofit];             height = cgrectgetheight(cell2.textview.bounds);      …     }      - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {          if (indexpath.row == 0) {             return 143;         }         if (indexpath.row == 1) {             return height;         }          return 0;     } 

you need implement heightforrowatindexpath.

say data displayed in textview stored in nsarray.

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {  cgfloat cellheight = 30; //assuming textview's origin.y 30 , textview last ui element in cell   nsstring *text = (nsstring *)[textarray objectatindex:indexpath.row];  uifont *font = [uifont systemfontofsize:14];// font should same of textview  cgsize constraintsize = cgsizemake(maxwidth, cgfloat_max);// maxwidth = max width textview   cgsize size = [text sizewithfont:font constrainedtosize:constraintsize linebreakmode:uilinebreakmodewordwrap];   cellheight += size.height; //you can add cell padding if want space below textview  }
