Button in UITableView is appearing twice in iPad Master View Controller

Question

Created a UITableView programmatically, data in my tableview in iPad Master View Controller is loaded dynamically, i am putting a button in the last cell, but the button is showing up again in the tableview underneath the cell... First time when the code is executed, the button appears only once, but next time it shows up twice... Here is the code...

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}

if([_objects count] > 1)
{

    if(indexPath.row == [_objects count])
    {            

        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

        //set the position of the button
        button.frame = CGRectMake(cell.frame.origin.x + 50, cell.frame.origin.y + 15, 225, 30);
        [button setTitle:@"Hide me" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(customActionPressed) forControlEvents:UIControlEventTouchUpInside];
        button.backgroundColor= [UIColor clearColor];
        [cell.contentView addSubview:button];

    }
    else
    {
        cell.textLabel.textAlignment = NSTextAlignmentCenter;
        cell.selectionStyle = UITableViewCellSelectionStyleBlue;
        cell.textLabel.textColor = [UIColor colorWithRed:0/255.0 green:100.0/255.0 blue:220.0/255.0 alpha:1.0];
        cell.textLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:13];
        cell.textLabel.text = [_objects objectAtIndex:indexPath.row];
        NSLog(@"%@", [_objects objectAtIndex:indexPath.row]);
    }
}

return cell;
}

Please write bellow code :

 if (cell)

   {

     cell =nil;

   }

before creating your tableview cell

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

//write here

if (cell)

   {

     cell =nil;

   }

//*

if (cell == nil) {

   cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
  }
