使用NIB定义从故事板出来的UITableViewCell
我使用Json数组来显示来自服务器的数据。
当我将CellIdentifier更改为我在CellIdentifier中使用的@Cell时，pushDetailView正在工作，它将进入下一页，但是当我再次更改为CustomCell时，只需在第一页中显示城市和州的名称，而当我点击时不会去下一页。 我需要@CustomCell的原因是因为在第一页需要2个标签视图，当我将其更改为@cell时，它只显示一个标签。
谢谢。

如果你没有为你的customcell当你推入一个单元格的时候你的方法didSelectRow：AtIndexPath将被调用。 你可以自己做一个pushViewController从该方法或[self performSegueWithIdentifier：@“pushDetailView”sender：self];
