ios - 找不到合适的方法来覆盖 RowsInSection xamarin

Question

   class CallHistoryDataSource : UITableViewSource
    {
        CallHistoryController controller;

        public CallHistoryDataSource (CallHistoryController controller)
        {
            this.controller = controller;
        }

        public override int RowSelected(UITableView tableView, int section)
        {
            return controller.PhoneNumbers.Count;
        }
        //
        // Returns a table cell for the row indicated by row property of the NSIndexPath
        // This method is called multiple times to populate each row of the table.
        // The method automatically uses cells that have scrolled off the screen or creates new ones as necessary.
        //
        public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
        {
            var cell = tableView.DequeueReusableCell (CallHistoryController.callHistoryCellId);

            int row = indexPath.Row;
            cell.TextLabel.Text = controller.PhoneNumbers [row];
            return cell;
        }
    }

`Helloworld_iOS.CallHistoryController.CallHistoryDataSource.RowSelected(UIKit.UITableView, int)' is marked as an override but no suitable method found to override (CS0115)

您好，我正在尝试使用 xamarin monotouch 制作一个 helloworld 应用程序，但我遇到了这个错误。有人可以帮我解决这个问题吗？

谢谢

我猜您使用的是统一 API。

在这种情况下使用这个(nint 而不是 int):

public override nint RowSelected(UITableView tableView, nint section)
