Xcode IOS高级链接UITableView

Question

我在Xcode中开发了一个选项卡式应用程序。我遇到了一个并发症。

我对我的进步感到满意，但在图2或场景2或SelectedCellViewController.m中，我不想看到像Pic1或Scene1下面的所有表格单元格。我只想看到一个表格单元格和相关表格单元格链接到图片3或场景3.

您可以在图片1或场景1中选择一个表格单元格，然后您可以看到您选择的颜色图片我会在图片下方加入一些信息。现在，您可以在Pic 2或Scene 2中看到图片下方有多个表格单元格。我只想显示相关表格单元，以便看到更大的版本，我已经编码了功能，但我很困惑如何摆脱Pic 2或Scene 2中的其他单元格。

我是不确定如何做到这一点，任何帮助将大大受到赞赏。

Answer 1

，因为在sitesArray值你的tableView有尽可能多的行。如果只有一个值，或者如果您更改了numberOfRowsInSection，则会得到一行表。

// Return the number of rows in a section 
- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section { 
    return 1; 
}
