下面是一個簡單的示例,用我的示例代碼中的NSArray(NSMutableArray)填充UITableViewController的子類。它不使用故事板,但你說在評論中沒問題。希望我的示例代碼可以幫助你。

NSMutableArray *_items;

你有你的tableview類的示例代碼?使它成爲UITableViewController的一個子類很容易。請包括頭文件和實現文件。 – chourobin 2012-01-04 00:33:11
@chourobin肯定的事情,只是將我的xcode項目源文件附加到我的原始文章。 – Jake 2012-01-04 00:44:46
@JakeRocheleau - 只是好奇,爲什麼你想讓你的Storyboard儘可能的苗條?我的印象是,界面構建器等Storyboarding允許您通過圖形處理來減輕代碼的負擔,並防止由於API更改而導致將來的錯誤。 – 5StringRyan 2012-01-04 00:56:01
