title: UITableViewCell UIButton Selection
body: <p>It would be great if someone can help to achieve the below requirement.
  In the tableviewcell, i have horizontal scrollview which will have uibuttons added dynamically. User can select multiple buttons from one row, but cannot select button from different rows. For e.g., If I have already selected buttons(i should be able to select one or more buttons) in row1, and when i tap button in row2, selected buttons in row1 should be deselected and the button which i tapped in row2 should be selected.</p>
  
  <pre><code>-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  
    cell.timeslotScrollView.contentSize = CGSizeMake(500, 0);
    cell.timeslotScrollView.scrollEnabled = YES;
    cell.timeslotScrollView.showsHorizontalScrollIndicator = NO;
  
    UIButton *button = [[UIButton alloc]init];
    button.frame = CGRectMake(0, 0, 68, 35);
    [button setTitle:@"abc" forState:UIControlStateNormal];
  
    button.layer.borderWidth = 2;
    button.layer.borderColor = [UIColor colorWithRed:0.23 green:0.71 blue:0.29 alpha:1.0].CGColor;
    button.layer.cornerRadius = 3;
    button.userInteractionEnabled = YES;
     [button setTitleColor:[UIColor colorWithRed:0.23 green:0.71 blue:0.29 alpha:1.0] forState:UIControlStateNormal];
    [button setTag:indexPath.row];
    [button addTarget:self action:@selector(didTap:) forControlEvents:UIControlEventTouchUpInside];
  
    UIButton *button1 = [[UIButton alloc]init];
    button1.frame = CGRectMake(button.frame.origin.x+68+buttonSpace, 0, 68, 35);
    [button1 setTitle:@"5 pm"  forState:UIControlStateNormal];
    [button1 setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];
