行選擇後不重新加載表視圖

Question

我遇到了searchDisplayController和自定義原型單元格的問題。我的故事板有一個帶有「Tulona」標識符的自定義原型單元格的表格視圖。故事板還有一個搜索顯示控制器。當搜索欄專注時，我想顯示一些搜索選項作爲基本單元格，並選擇一個選項後，我想用該自定義單元格重新加載表。我申請下面的代碼。選擇一個選項後不會完全刷新/重新加載後，除表格視圖之外，所有內容都是完美的。當我從顯示控制器的表格視圖中選擇一個選項時，主表格視圖（帶有「Tulona」單元格的故事板表格）不會出現。如果我從搜索欄點擊取消按鈕，主表視圖確實出現在自定義單元格中。請讓我知道爲什麼主表沒有從顯示控制器表視圖中選擇選項後重新加載？我是iOS開發新手。我很抱歉，如果這是真的很明顯或容易，我只是錯過了它。如果有的話，請指出正確的方向..謝謝。

我已經通過將這些線didSelectRowAtIndexPath方法函數解決我的問題 -

dispatch_async(dispatch_get_main_queue()){ 
       self.tableView.reloadData() 
       self.searchDisplayController!.setActive(false, animated: true) 
       println("Table view should reload") 
      }
