我在Xcode中開發了一個選項卡式應用程序。我遇到了一個併發症。Xcode IOS高級鏈接UITableView
我對我的進步感到滿意,但在圖2或場景2或SelectedCellViewController.m中,我不想看到像Pic1或Scene1下面的所有表格單元格。我只想看到一個表格單元格和相關表格單元格鏈接到圖片3或場景3.
您可以在圖片1或場景1中選擇一個表格單元格,然後您可以看到您選擇的顏色圖片我會在圖片下方加入一些信息。現在,您可以在Pic 2或Scene 2中看到圖片下方有多個表格單元格。我只想顯示相關表格單元,以便看到更大的版本,我已經編碼了功能,但我很困惑如何擺脫Pic 2或Scene 2中的其他單元格。
我是不確定如何做到這一點,任何幫助將大大受到讚賞。

我會怎樣改變//返回的部分 行數 - (NSInteger的)的tableView:(UITableView的*)表numberOfRowsInSection:(NSInteger的)部分{ 回報1;只能在Pic2或Scene 2中顯示相關的表格單元格。在Scene 2中,我需要顯示相關的表格單元格。 EG如果你點擊顏色梅花樹,你會轉到第二個地方你看到一個樣本和一些信息,我想只能在場景2中顯示梅花樹的表格單元,所以點擊時你會轉到場景3,更大的版本。我認爲你是對的,我需要改變行數來只顯示相關數組。 } –
