我有一個根視圖控制器，它組成了頂部的搜索欄和底部的子表視圖控制器。我使用的成分，而不是因爲這些原因指定的搜索欄，以表視圖的標題：UISearchDisplayController不完全覆蓋子視圖控制器
- 我不想索引與搜索欄（如聯繫人應用程序）重疊。
- 我希望搜索欄變得粘滯。也就是說，當我滾動表格視圖時它不會移動（再次像聯繫人應用程序）。
- 我的表格視圖已經有一個標題。
由於搜索欄位於根視圖控制器中，我還在根視圖控制器中實例化了我的搜索顯示控制器。我尋求建議的搜索UI有兩個問題：
- 半透明灰色疊加層不覆蓋整個子表視圖。它留下標題的頂部和索引可見。
- 同樣，搜索結果表不包括整個子表視圖。我知道如何手動更改此結果表格視圖的框架，但這樣做只能解決此問題......灰色半透明覆蓋圖的框架未鏈接到結果表視圖框架。他們沒有財產訪問覆蓋。
1）閒置
2）輸入搜索欄
3）開始輸入
