如果我添加UISearchBar而不将其引用到UISearchDisplayController，则我的tintColor将正确显示。

searchBar.barTintColor = [UIColor colorWithRed:200.0f/255.0f green:21.0f/255.0f blue:26.0f/255.0f alpha:1.0f];

但是，如果我将我的UISearchBar引用到UISearchDisplayController，则颜色似乎有所不同...

searchBar = [[UISearchBar alloc] init];
[searchBar setBarTintColor:[UIColor colorWithRed:200.0f/255.0f green:21.0f/255.0f blue:26.0f/255.0f alpha:1.0f]];
searchBar.delegate = self;
searchBar.searchBarStyle = UISearchBarStyleProminent;
searchBar.placeholder = @"Buscar restaurantes o platillos";
searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;

searchController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
    searchController.delegate = self;

self.tableView.tableHeaderView = searchBar;

我在AppDelegate上的tintColor设置是

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:200.0f/255.0f green:21.0f/255.0f blue:26.0f/255.0f alpha:1.0f]];
[[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
[[UIToolbar appearance] setBarTintColor:[UIColor colorWithRed:200.0f/255.0f green:21.0f/255.0f blue:26.0f/255.0f alpha:1.0f]];
self.window.tintColor = [UIColor whiteColor];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
self.window.backgroundColor = [UIColor colorWithRed:200.0f/255.0f green:21.0f/255.0f …
