MonoTouch - 如何清除數據源時立即重繪UITableView

Question

在MonoTouch中，當我清除其數據源時，如何立即重繪空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 

感謝

你打電話從什麼地方tbl.ReloadData();？
