iphone table view check mark accessory problem!!!

Answer 1

You have to set cell.accessoryType in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

The fact is that as you have a reuse identifier, when a new cell is requested, a cell with the identifier is copied. As you have set the checkmark in the latest cell, the checkmask is copied.

You have to store the state of each cell (ie in an array) to recreate the cell with the right value.

Something like that:

BOOL values[50]; //Not the best way, but easy for the example...


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  static NSString *CellIdentifier = @"Cell";
  TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  if (cell == nil) {
    cell = [[[TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
  }
  cell.textLabel.text=[NSString stringWithFormat:@"%i",[indexPath row]];
  if (value[indexPath.row]) { 
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
  } else {
    cell.accessoryType = UITableViewCellAccessoryNone;
  }
  return cell;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
  UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

  values[indexPath.row] = !value[indexPath.row];

  if (value[indexPath.row]) { 
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
  } else {
    cell.accessoryType = UITableViewCellAccessoryNone;
  }
}

You can do it with the help of array , take one array and each array hold a dict do this condition in array
NSMutableArray *arr = [[NSMutableArray alloc]init]; for(int i=1; i<=50;i++) { NSmutableDictionary *dict = [[NSMutableDictionary alloc]init]; [dict setobject:[nsstring stringwithformat:@"%d",i] valueForkey:@"ID"]; [arr addobject:dict]; [dict release]; }

now rows is [arr count]; and put this check in cell appearence nsmutabledict *dict1 = [arr objectatindex:indexpath.row]; if([[dict objectforkey:"Check"]==nil]) { [dict setobject:[nsstring stringwithformate:@"1"] valueforkey:@"Check"]; }else { if([[dict objectforkey:"Check"] isequaltostring:@"1"] { cell.accessoryType = UITableViewCellAccessoryNone; } else { cell.accessoryType = UITableViewCellAccessoryCheckmark; } }

not put below code in didselect methood nsmutabledict *dict1 = [arr objectatindex:indexpath.row]; if([[dict objectforkey:"Check"] isequaltostring:@"1"] { [dict setobject:[nsstring stringwithformate:@"2"] valueforkey:@"Check"]; } else { [dict setobject:[nsstring stringwithformate:@"1"] valueforkey:@"Check"]; }
