custom ios tableview cell not working

Question

I have a custom tableview cell, if the cell is clicked then the cell should be expanded and if not clicked then the cell should not be expanded.

There is also a custom view and if the cell is clicked, I want the height of the custom view to be increased and if the cell is not clicked then it should be a certain height.Below this code is set in cellForRowAt

 if TableView.rowHeight == 126 {

            cell.CustomView = UIView(frame: CGRect(x: 7, y: 8, width: 359, height: 20))

            return cell
        }
        else{

        }

But the code I set to change the height of the view is not working and I am not sure where to go from there

When the cell is not clicked this is how my custom View looks like:

When the cell is clicked this is what the custom view looks like:

As you can see my problem is when the cell is not clicked, the bottom of the View is a straight line but when the cell is clicked, the bottom is rounded. I want the View to also be rounded when the cell is not clicked.

Answer 1

Call beginUpdates and endUpdates to force tableView to update heights

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    // new row selected
    self.selectedIndex = indexPath
    tableView.beginUpdates()
    tableView.endUpdates()
}
