ios - 如何以编程方式关闭 UISearchBar？

Question

我正在使用 UISearchController 和 UITableView。 When a cell in the UITableView is selected, I'm adding a black UIView above the whole screen with some subviews on it.当 UISearchController 处于非事件状态时，它工作得很好。但是当它处于事件状态时，UISearchBar 会显示在我的黑色 View 上方。

self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.scopeButtonTitles = [NSArray array];
self.searchController.searchBar.delegate = self;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.searchBar.backgroundImage = [self imageWithColor:[MySingleton shared].barTintColor];
[self.searchController.searchBar sizeToFit];
[self.view addSubview:self.searchController.searchBar];

---

myView = [[UIView alloc] initWithFrame:CGRectMake(0, -64, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
    myView.backgroundColor = [UIColor blackColor];
    myView.layer.opacity = 0.9;
[self.view addSubview:myView];

我试过在放置 View 之前使其处于非事件状态，

self.searchController.active = NO;

并将 myView 添加到导航 Controller 的 View 中

[self.navigationController.view addSubview:myView];

仍然没有运气。有什么想法吗？

有一种方法允许您在 View 层次结构中的另一个 View 之上插入一个 View ，该方法称为:- insertSubview:aboveSubview:。以下是您可以如何使用它:

if (self.searchController.searchBar)
    [self.view insertSubview:myView aboveSubview:self.searchController.searchBar];
else
    [self.view addSubview:myView];
