同じUIViewControllerの最初のUITableViewのRowClickに2番目のUITableViewをバインドします。

Question

2つのUITableViewが同じUIViewControllerにあります。 tblView1 & tblView2。

両方のTableViewがデータを動的に持ち出しています。 私の問題は次のとおりです。tblView1のSelectedRowに基づいて、tblView2にデータをロードします。

たとえば、tblView1から会社名を選択すると、tblView2はその会社が作成した車を入力する必要があります。

私は最初のテーブル（tblView1）のrowIndexを持っていますが、tblView1のRowSelectedメソッドからtblView2をバインドできません。 私のtblView2をバインドする際に助けが必要です。 どうすればいいですか？
