In the scenario mentioned in the question title, on changing the segment, ideally the UITableView
should reload and hence the UITableViewCell
should also reload. The issue is, all the content gets updated like label texts. But if I have expanded a subview of cell in one segment, it remains still expanded after segment is changed.
Segment index change function :
@IBAction func segmentOnChange(sender: UISegmentControl)
{
// Few lines
// self.tableMenu.reloadData()
}
Screenshot 1 :
Screenshot 2 :
So ideally, in screenshot 2, the cart view should have been collapsed.
Update :
Show/Hide view :
func showHideCartView(sender: UIButton)
{
let cell = self.tableMenu.cellForRow(at: IndexPath(row: 0, section: Int(sender.accessibilityHint!)!)) as! RestaurantMenuItemCell
if sender.tag == 1
{
// Show cart view
cell.buttonArrow.tag = 2
cell.viewAddToCart.isHidden = false
cell.constraint_Height_viewAddToCart.constant = 50
cell.buttonArrow.setImage(UIImage(named: "arrowUp.png"), for: .normal)
}
else
{
// Show cart view
cell.buttonArrow.tag = 1
cell.viewAddToCart.isHidden = true
cell.constraint_Height_viewAddToCart.constant = 0
cell.buttonArrow.setImage(UIImage(named: "arrowDown.png"), for: .normal)
}
self.tableMenu.reloadData()
}
cellForRowAtIndexPath :
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "RestaurantMenuItemCell", for: indexPath) as! RestaurantMenuItemCell
cell.selectionStyle = .none
let menuItem = self.menuItems[indexPath.section]
cell.imageViewMenuItem.image = UIImage(named: "recommend0@2x.png")
cell.labelName.text = menuItem.name
cell.labelDescription.text = menuItem.description
cell.labelPrice.text = String(format: "$%i", menuItem.price!)
cell.buttonArrow.accessibilityHint = String(format: "%i", indexPath.section)
cell.buttonArrow.addTarget(self, action: #selector(self.showHideCartView(sender:)), for: .touchUpInside)
return cell
}
Since you rely on the sender button's tag to determine whether the cell should be shown in expanded or collapsed state, you need to make sure that when the segment changes, the tags for all the cells' buttonArrow
also change to 1.
Unless that happens, the cells will be reused and since the buttonArrow
's tag is set to 2, it will be shown as expanded.
