UISearchBar MinimalStyle选择颜色

Question

我的UISearchController中的UISearchBar在点击它时表现得很有趣。

酒吧外观有三种状态。

1：未开启

2：点击

3：点击文字

如您所见，第三个颜色已关闭。它的颜色是白色，而不是像其他颜色一样黑。

这是包含UISearchController和amp;的设置的代码块。的UISearchBar

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];

UINavigationController *navController = (UINavigationController *)[storyboard instantiateViewControllerWithIdentifier:@"searchVC"];

self.theSearchController = [[UISearchController alloc] initWithSearchResultsController:navController];

self.theSearchController.searchResultsUpdater = self;

self.theSearchController.searchBar.placeholder = @"Search";
self.theSearchController.delegate = self;
self.theSearchController.dimsBackgroundDuringPresentation = YES;
self.theSearchController.searchBar.delegate = self;

self.theSearchController.hidesNavigationBarDuringPresentation = YES;
self.definesPresentationContext = YES;

[self.theSearchController.searchBar sizeToFit];

[self.theSearchController.searchBar setTintColor:[UIColor whiteColor]];
[self.theSearchController.searchBar setBarTintColor:[UIColor blackColor]];
[self.theSearchController.searchBar setSearchFieldBackgroundImage:[UIImage imageNamed:@"SearchBG.png"] forState:UIControlStateNormal];
[self.theSearchController.searchBar setBarStyle:UIBarStyleBlackTranslucent];
[self.theSearchController.searchBar setSearchBarStyle:UISearchBarStyleMinimal];

[self.tableView setTableHeaderView:self.theSearchController.searchBar];

Answer 1

我在故事板文件中偶然发现了答案。

UISearchController连接的UINavigationController当然有一个UINavigationBar。当您点击并插入一个字母时，UISearchBar会混合到UINavigationBar中，继承它的颜色。一旦我将UINavigationBar的样式设为Black，UISearchBar继承了它并且它有效。
