Question

您好我想问的问题是有没有办法在Objective C中创建这样的代码，这样我就可以在UICollectionViewCell中选择一个UICollectionViewController并将其链接到表格视图根据选择的UICollectionViewCell显示UICollectionViewCell特定内容，而不创建数百个UITableViewControllers？

知道这不是代码，但这是我希望代码在可能的情况下实现的目的：

单击集合视图单元格连接显示表视图。

然后在表格视图中......

如果点击的集合视图是礼服展示礼服表视图。

肯定这有可能吗？

此外，如果可能的话，我希望代码以某种方式将事物分组，因为这将在大规模上完成我有106个集合视图单元，需要链接到表视图，每个表视图需要包含至少30个TableViewCell。 / p>

我尝试了你的问题以获得解决方案。最后我成功地得到了解决方案.Below代码完美无缺。

在ViewController中
