Question

How can I store a boolean value in each row of a UITableview. I need to retrieve the boolean value stored in the cell, when that particular cell is selected.

Answer 1

I recommend to use tag property in UITableViewCell.

- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath;            
// returns nil if cell is not visible or index path is out of range
{

    static NSString *identifier = @"MyIndetifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault     reuseIdentifier:CellIdentifier] autorelease];
  }
  //make sure tu put here, or before return cell. 
  cell.tag = 0; //0 =NO, 1=YES;

  return cell;
}

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    BOOL boolean = cell.tag; // return 0 or 1. based on what boolean you set on this particular row.
}
