从搜索显示控制器滚动结果时导航栏消失
我有一个带有搜索栏和搜索显示控制器的视图。它是导航控制器的根视图。搜索显示控制器充当搜索栏的自动完成功能。 问题如下： 我在搜索栏中输入一个字母，然后会出现自动完成结果。我向下滚动到结果表视图的末尾。之后我改变主意，又输入了几个字母，直到表格中只剩下 3 个单词。我在表中选择一个结果。在 didSelectRowAtIndexPath 中，我保存了所选的值，并使用 setActive: FALSEanimated: TRUE 停用搜索显示控制器。当它停用时，导航栏会丢失。我做错了什么？
示例：我输入 H。出现一长串关键字。我向下滚动。我改变主意并输入OT，因此搜索栏中的文本现在是HOT，大约有。还剩 6 个关键字，我选择 HOTEL。当我回来时，导航栏消失了。我杀死了这个应用程序，因为它没用。下次我输入 HOT ；没有先向下滚动查看所有结果，然后选择HOTEL。这次可以了，导航栏还在。
编辑：我认为当我必须滚动结果时，如果只有一页结果可以正常工作，就会出现问题。
I have a view with a search bar and a search display controller. It is the root view of a navigation controller. The search display controller acts as an autocomplete for the search bar.
The problem is the following:
I enter a letter in the search bar and the autocomplete results appear. I scroll down to the end of the results table view. After that I change my mind and type in another few letters until there are only 3 words in the table. I select a result in the table. In the didSelectRowAtIndexPath I save the value that was selected and deactivate the search display controller using setActive: FALSE animated: TRUE. When it deactivates the navigation bar is missing. What did I do wrong?
Example: I type in H. A long list of keywords appear. I scroll down. I change my mind and type OT so the text in the search bar is now HOT there are approx. 6 keywords remaining, I select HOTEL. When I'm back the navigation bar is gone. I kill the app since it's useless. Next time I type in HOT ; without first scrolling down to see all the results, and after that I select HOTEL. This time it works, the navigation bar is still there.
EDIT: I think the problem appears when I have to scroll through the results if there is only one page of results it works ok.
