我以编程方式创建了一个带有范围栏的搜索 Controller ，但我无法更改范围栏的色调。我使用以下代码创建了搜索 Controller :
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
searchController.searchBar.placeholder = "Search Buildings or Codes"
navigationItem.searchController = searchController
definesPresentationContext = true
searchController.searchBar.scopeButtonTitles = ["Building Names", "Building Codes"]
searchController.searchBar.delegate = self
搜索栏还有一个取消按钮，我使用以下代码更改了色调:
UIBarButtonItem.appearance(whenContainedInInstancesOf:[UISearchBar.self]).tintColor = UIColor.red
非常感谢您的帮助。
最佳答案
let darkRed = UIColor(red: 0.392, green: 0.012, blue: 0.020, alpha: 1.00)
searchController.searchBar.tintColor = darkRed
