iOS UITableView “'Manandrana mamorona sary mihetsika roa ho an'ny sela '”

Manana sela customTableView aho - te-hanavao ny sela fotsiny aho (mifototra amin'ny hetsika tambajotra mitranga).

Ka rehefa nanao ny antso an-tamba-jotra aho dia manao:

 - (void)makeNetworkCall
 {

      [self.tableView beginUpdates];

      // MAKE_NETWORK_CALL

      [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] 
                    withRowAnimation:UITableViewRowAnimationNone];


       [self.tableView endUpdates]; // SIGABRT OCCURS HERE ON SECOND CALL
 }

 - (void)networkDataReturned:(NSDictionary*)dataReturned
 {
     // UPDATE_TABLE_VIEW_DATA_MODEL       

     [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] 
                    withRowAnimation:UITableViewRowAnimationNone];

  }

Tena mety izany. fotoana voalohany niantsoana ny hetsika tambajotra, na izany aza raha tapitra ny sela (miantso ny hetsika tambajotram-pifandraisana indray, ny valiny dia nitazona izany) dia mahazo ity lesoka manaraka ity aho:
