UITableView和UISegmentedControl

我是iPhone開發的新手。我有一個UITableView有三個部分，每個部分有三個行。我有一個UISegmentedControl有三個索引。tableview最初是隱藏的。當我選擇segmentIndex的任何索引時，它將顯示帶有三個部分的tableview。但我的問題是，當我選擇分段控制則其顯示的tableView的指標只有一個部分和另外兩個部分是隱藏在tableView.How做到這一點請回答
這裏是我的代碼UITableView和UISegmentedControl

reloed表的表中的每一個部分都顯示三段在我的tableview。但是我只想顯示一個部分，另外兩個部分是隱藏的。 – 2013-03-06 06:23:58

非常感謝。它按我的需要完美地工作。 – 2013-03-06 12:22:38

@parthpatel如果你確定這個，接受答案.... – Venkat 2013-03-06 13:33:43

我相信我明白你想要做什麼，你想顯示不同的表格視圖單元取決於哪個按鈕段被選中。

你需要讓你的cellForRowAtIndexPath檢查選中哪個段並返回正確的一組單元。

當用戶更改分段按鈕時，請使用changeSegment：將選定的段存儲在實例變量中。然後讓它調用[self reloadData];

它的小工第一次按鈕段選中它的顯示一段和其他隱藏但是第二次顯示兩段和第三次用三段選擇按鈕段顯示錶格我想每次按鈕段選擇其顯示只有一個部分和其他兩個隱藏 – 2013-03-06 06:59:34
