UISearchBarSearchContainerView是黑色的

Question

为什么是黑色？在viewDidLoad中设置此代码：

var searchController = UISearchController(searchResultsController: nil)
searchController.obscuresBackgroundDuringPresentation = false
navigationItem.searchController = searchController
definesPresentationContext = true
navigationItem.hidesSearchBarWhenScrolling = false
searchController.delegate = self
searchController.searchBar.delegate = self

Answer 1

尝试更改搜索栏的样式。

看起来像

searchController.searchBar.barTintColor = .white
