我正在製作像iOS應用程序的目錄。使用Xcode 4.2和故事板。如何從選定的UITableView跳轉到scrollView？
此應用程序有兩個視圖，每個視圖都可以通過標籤欄控制器進行更改。
應用程序圖像在這裏。 http://www.0502.me/help/xcode-cat.png
我做了目錄視圖和Table of Contents（TableView）。 但我無法將目錄視圖從目錄視圖更改。
我覺得當目錄的頁碼值被點擊時，目錄視圖的變量和視圖的變化會是很好的結果。
第一視圖是目錄視圖。 它由FirstViewController控制，並且爲了更改圖像比例，PageView類也可以使用。
第二視圖是目錄，由ListViewController控制。它解析plist（xml），並操作單元格值（標題和頁碼）。
代碼如下，請幫忙。

謝謝您的回覆，鎮流器。 我試圖「你的第二個iOS應用程序」，但發現錯誤。 可能是故事板設置不正確。 我會重新嘗試，謝謝。 – 2012-02-09 09:10:26
