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颜色：

UIBarButtonItem.appearance(whenContainedInInstancesOf:[UISearchBar.self]).tintColor = UIColor.red

Thank you so much for your help.
