UISearchController - 空白区域隐藏状态栏

Question

我正在使用 UISearchController，它工作正常。然而，它在搜索栏上留下了一个空白区域（当它被聚焦时），它部分隐藏了状态栏。 This espace

我已经尝试设置self.edgesForExtendedLayout = UIRectEdgeNone 和self.navigationController.extendedLayoutIncludesOpaqueBars = YES，但空间仍然存在。我尝试设置self.definesPresentationContext = YES;，但它生成了searchBar 占据状态栏位置like this。

我正在使用嵌入在UINavigationController 中的UIViewController。这是我现在实施的设置：

@interface DirectoryViewController :  UIViewController <UITableViewDataSource , UITableViewDelegate ,UISearchBarDelegate, UISearchControllerDelegate, UISearchResultsUpdating>

@property (strong, nonatomic) NSMutableArray *personsArray;
@property (nonatomic, strong) UISearchController *searchController;
@property (nonatomic, strong) NSMutableArray *searchResults;


@implementation DirectoryViewController

- (void)viewDidLoad {
    [super viewDidLoad];
UINavigationController *searchResultsController = [[self storyboard] instantiateViewControllerWithIdentifier:@"TableSearchResultsNavController"];

    // Our instance of UISearchController will use searchResults
    self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];

    // The searchcontroller's searchResultsUpdater property will contain our tableView.
    self.searchController.searchResultsUpdater = self;
    self.searchController.delegate = self;
    self.searchController.searchBar.delegate = self;

    //Cancel button tint
    _searchController.searchBar.tintColor = [UIColor whiteColor];
    [self.searchController.searchBar setBackgroundImage:[UIImage imageNamed:@"navBar"]
                                                forBarPosition:0
                                                    barMetrics:UIBarMetricsDefault];

    if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) { /// iOS 7 or above
        self.edgesForExtendedLayout = UIRectEdgeNone;
    }

    self.navigationController.extendedLayoutIncludesOpaqueBars = YES;

}

感谢您的帮助。谢谢

我在This answer 中找到了解决方案。

改变tableInsets：

    self.directoryTable.contentInset = UIEdgeInsetsMake(-10, 0, 0, 0);

当searchController成为FirstResponder时

和

    self.directoryTable.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);

当搜索栏操作完成时。
