MonoTouch - 清除数据源时如何立即重绘UITableView

Question

在MonoTouch中，当我清除其数据源时，如何立即重绘空UITableView？

List<string> ds = new List<string>();

UITableView tbl = new UITableView();
tbl.DataSource = new MyTableViewDataSource(ds);
//And the other parts(datasource class, delegate class etc.) are truely coded when i try to do somewhere at my program, something like
ds.Add("new string");
//it works and table shows new data too, but when i say
ds.Clear();
//it works and clear but table is not redrawn

你是从某个地方打电话给tbl.ReloadData ();吗？
