关闭UITableViewController时保留选定的行-Swift，UITableView

Question

Does anyone know how to keep the rows selected/highlighed in UITableView when you move from a new View Controller back to your UITableView?

When I make a selection and dismiss the table view controller, the selection is no longer there when I return. I set clearsSelectionOnViewWillAppear to false inside super.viewDidLoad but that didn't work, someone on StackOverflow mentioned doing the following:

class TableViewController:
UITableViewController,
UITableViewDelegate,
UITableViewDataSource {


@IBOutlet weak var drugTableView: UITableView!

override func viewDidLoad()
    {
    super.viewDidLoad()
    self.clearsSelectionOnViewWillAppear = false

    }


override func viewWillAppear(animated: Bool) {

let indexPaths = self.drugTableView.indexPathsForSelectedRows() as [NSIndexPath]

self.tableView.selectRowAtIndexPath(indexPath: indexPaths, animated: true, scrollPosition: UITableViewScrollPosition.None)

}

but that won't compile due to this error:

self.tableView.selectRowAtIndexPath(indexPath: indexPaths, animated: true, scrollPosition: UITableViewScrollPosition.None) Cannot convert the expression's type '(indexPath: [AnyObject]?, animated: BooleanLiteralConvertible, scrollPosition: UITableViewScrollPosition)' to type 'BooleanLiteralConvertible'

Could someone help me out with this one, this is such a headache.

Thank you.

尝试在表视图控制器clearsSelectionOnViewWillAppear设置为false。
