推送View时，UISearchController不会被解雇 [英] UISearchController not dismissed when View is pushed
问题描述
我知道这是一篇很长的文章，但这只是我保证的一个问题。
I know this is a long write-up, but it's just one issue I promise.
我在使用UISearchController时遇到了一些非常奇怪的行为。让我描述一下层次结构，然后我将逐步解释我的视频中发生的事情：
I'm getting some very strange behavior with a UISearchController. Let me describe the hierarchy, then I'll explain step by step what happens in my video:
你看到的第一个视图是一个常规的ViewController，带有一个tableView和UISearchController作为完全独立的实体。 UISearchController有自己的searchResultsController，我在创建时设置它：
The first view you see is a regular ViewController, with a tableView and the UISearchController as completely separate entities. The UISearchController has its own searchResultsController that I set when I create it:
let searchResultsController = MyResultsControllerClass()
searchController = UISearchController(searchResultsController: searchResultsController)
这是基本设置。
MyResultsControllerClass 有一个tableView，以及一个指向主视图控制器的指针，所有这些视图都放在其中。当searchController的searchBar开始搜索时，你会看到tableView显示出来。然后我点击一个结果，编程俱乐部。 MyResultsControllerClass 使用指向主视图的指针推送新的视图控制器（只是关于该事件的详细信息），如下所示：
The MyResultsControllerClass has a tableView, as well as a pointer back to the master view controller all these views are housed in. When the searchController's searchBar begins searching, you see that tableView show up. Then I tap a result, Programming Club. The MyResultsControllerClass uses the pointer to the master view to push a new view controller (just details about that event) like so:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let activityDetail = ActivityDetailViewController(nibName: nil, bundle: nil, activity: searchResults[indexPath.row])
parentController?.navigationController?.pushViewController(activityDetail, animated: true)
}
你可以看到这发生在searchBar后面，但是searchController并没有被所呈现的视图掩盖！这是我的问题。如您所见，我仍然可以与之互动。当我按取消时，它最终消失。
You can see this happen behind the searchBar, but the searchController is not "covered up" by the presented view! This is my issue. As you can see, I can still interact with it. When I press "Cancel", it finally disappears.
现在，我认为这可能与UISearchController的事实有关实际上是一个UIViewController，如果我理解正确的话。所以我试图从UISearchController推送，没有任何反应。我尝试将UISearchController嵌入到自己的UINavigationController中并从searchController.navigationController推送，没有任何反应。我可以在推送之前完全取消编辑，但我希望编辑在导航时仍然存在。
Now, I thought this might have to do with the fact that a UISearchController is in fact a UIViewController, if I understand correctly. So I attempted pushing from the UISearchController, nothing happens. I tried embedding the UISearchController in its own UINavigationController and pushing from searchController.navigationController, nothing happens. I can completely cancel the editing before pushing, but I want the editing to still exist when they navigate back.
我做错了什么？有没有更好的方法呢？
What am I doing wrong? Is there a better way to do this?
推荐答案
我有同样的问题，我通过设置解决了这个问题：
I have the same exact issue, I have solved it by setting:
self.definesPresentationContext = YES;
。这是Apple在WWDC会议228中推荐的，请在此处阅读： http://asciiwwdc.com/2014/sessions/228。
