无法从 UISearchDisplayController 委托推送视图控制器
我创建了一个 UISearchDisplayController，它使用单独的 UITableViewController 作为委托来显示搜索结果。在这个视图控制器中，我有“didSelectRowAtIndexPath”方法，该方法分配并初始化一个detailViewController，然后使用：
[[self navigationController] pushViewController: detailViewController animated: YES];
将其推入堆栈。然而，这条线不起作用。当点击一个单元格时，什么也不会发生。正在调用“didSelectRowAtIndexPath”，但“pushViewController”方法调用不起作用。我不再处于我的 navigationController 的上下文中了吗？我该如何解决这个问题？
任何帮助将不胜感激。
I have created a UISearchDisplayController which uses a separate UITableViewController as the delegate to display the results of the search. In this view controller, I have the 'didSelectRowAtIndexPath' method which allocates and initializes a detailViewController then uses:
[[self navigationController] pushViewController: detailViewController animated: YES];
to push it onto the stack. However, this line doesn't work. When a cell is tapped, nothing happens. 'didSelectRowAtIndexPath' is being called, but the 'pushViewController' method call isn't working. Am I not in the context of my navigationController any more? How can I fix this problem?
Any help would be much appreciated.

你的表的navigationController可能是错误的，我认为你可能想将它推到你的UISearchDisplayController的navigationController上。
为此，您可以使用“pushViewController”方法在 tableviewcontroller 中创建一个协议，并让 UISearchDisplayController 实现它。
然后，您在表视图中注册此委托，并在“didSelectRowAtIndexPath”中调用 PushViewcontroller 上的委托
your table's navigationController is probably the wrong one, I think that you might want to push it on the navigationController of your UISearchDisplayController.
To do this, you can create a protocol in your tableviewcontroller with a method "pushViewController" for instance and have UISearchDisplayController implement it.
Then your register this delegate in your table view and you call your delegate on pushViewcontroller in your 'didSelectRowAtIndexPath'
