Question

How do I know which row is currently selected in table view without using any global variable to store last clicked row using this method.

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 

Answer 1

You don’t need a global variable. if you need to track the currently selected row, you can create a member variable (iVar) in the class that is the delegate for the table view callbacks.

That method passes you the indexPath which has the row that was selected. If you want remember that for other function callbacks, then create a property or iVar in that class.

In header:

@interface MyTableViewController : UITableViewController {
    NSInteger _selectedRow;
}

In implementation

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
   _selectedRow = indexPath.row;
}
