I have a Main UITableView. I have created a custom UITableviewCell. I have set up another Sub UITableview to be displayed within the Custom Cell.
The Main Tableview has expandable and collapsing sections. When any section expands it shows the Custom Cell views. The Custom Cell also has another UITableView implemented with the same expanding and collapsing sections and this is creating a problem as the height of the Main Tableview and the Custom Cell is not updating itself to accommodate these subcells. So this tends to hide the Sub Tableview Cells.
Please advise what can be done here
