Expand and Collapse tableview cells

If you want the cell to get physically bigger, then where you have your store IndexPath, in heightForRow: use:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {    if selectedIndexPath == indexPath {      return 230 + extraHeight    }    return 230.0}

Then when you want to expand one in the didSelectRow:

selectedIndexPath = indexPathtableView.beginUpdatestableView.endUpdates

Edit

This will make the cells animate themselves getting bigger, you dont need the extra animation blocks in the cell.

Edit 2

 override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {        if(selectedIndexPath == indexPath) {          selectedIndexPath = nil          if let cell = tableView.cellForRowAtIndexPath(indexPath) as? MyTicketsTableViewCell {            cell.collapse()          }          if let cell = tableView.cellForRowAtIndexPath(NSIndexPath(forRow:indexPath.row+1, section: indexPath.section) as? MyTicketsTableViewCell {            cell.collapse()          }        } else {          selectedIndexPath = indexPath          if let cell = tableView.cellForRowAtIndexPath(indexPath) as? MyTicketsTableViewCell {              cell.expand()          }          if let cell = tableView.cellForRowAtIndexPath(NSIndexPath(forRow:indexPath.row+1, section: indexPath.section) as? MyTicketsTableViewCell {             cell.expand()          }        }        tableView.beginUpdates()        tableView.endUpdates()    }

All you need is implement UITableView Delegate this way:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {    return UITableViewAutomaticDimension}override func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {    return UITableViewAutomaticDimension}

By default, estimatedHeight is CGRectZero, when you set some value for it, it enables autoresizing (the same situation with UICollectionView), you can do even also so:

tableView?.estimatedRowHeight = CGSizeMake(50.f, 50.f); 

Then you need to setup you constraints inside your cell.

Hope it helps)

In MyTicketsTableViewController class, inside cellForRowAtIndexPath datasource method add target for the button.

cell.expandButton.addTarget(self, action: "expandorcollapsed:", forControlEvents: UIControlEvents.TouchUpInside)
