ios - cellForRowAtIndex is taking time to load cell from xib -

i have created custom uitableview class xib.

in -cellforrowatindex following code written.

the issue takes 2-3 sec push screen contains tableview.

       (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath   {          static nsstring *simpletableidentifier = @"mycell";          customcell *cell = (customcell *)[tableview dequeuereusablecellwithidentifier:simpletableidentifier];          if (cell == nil)         {             nsarray *nib = [[nsbundle mainbundle] loadnibnamed:@"customcell" owner:self options:nil];             cell = [nib objectatindex:0];          }          cell.selectionstyle = uitableviewcellselectionstylenone;           if(!indexpath.row)         {          uiview *separatorview = [[uiview alloc]initwithframe:cgrectmake(20,14, screenwidth-40, 1)];             separatorview.backgroundcolor = [uicolor colorwithwhite:0.4 alpha:0.6];             [cell addsubview:separatorview];             self.view.backgroundcolor = [uicolor whitecolor];         }         else         {             uiview *separatorview = [[uiview alloc]initwithframe:cgrectmake(20,6, screenwidth-40, 1)];             separatorview.backgroundcolor = [uicolor colorwithwhite:0.4 alpha:0.6];             [cell addsubview:separatorview];             self.view.backgroundcolor = [uicolor whitecolor];         }          tableview.scrollenabled = yes;         self.view.backgroundcolor = [uicolor whitecolor];         return cell; } 

i have debug code when return numberofrows 0 screen pushed immediately. if return 1 row takes 2-3 sec load.

i creating tableview programmatically.

edit

i have added in viewdidload after creating table:

   uinib *cellnib = [uinib nibwithnibname:@"customcell" bundle:nil];     [mtableview registernib:cellnib forcellreuseidentifier:@"mycell"]; 

and cellforrowatindex method:

  customcell *cell = (customcell *)[tableview dequeuereusablecellwithidentifier:@"customcell"];          cell.selectionstyle = uitableviewcellselectionstylenone;          if(cell == nil){              cell = (customcell *)[[[nsbundle mainbundle] loadnibnamed:@"customcell" owner:nil options:nil] lastobject];             [cell setrestorationidentifier:@"mycell"];             self.view.backgroundcolor = [uicolor whitecolor];           } 

but nothing chaneged

you need register loaded nib once reusing identifier table view can deque identifier, dequeing identifier alltime returning nil guess.

the best place register nib in viewdidload using

[self.tableview registernib:cellloadedfromnib forcellreuseidentifier:@"mycell"]; 

then access in cellforrowatindexpath: using following

[tableview dequeuereusablecellwithidentifier:@"mycell" forindexpath:indexpath]; 

make sure registering nib in tableview after tableview been initiated.
