【问题描述】：

我正在尝试使用以下代码更新搜索栏外观。

    searchController.searchBar.searchBarStyle = .prominent
    searchController.searchBar.backgroundColor = UIColor.clear
    searchController.searchBar.barTintColor = UIColor.black

它不会改变颜色。

【参考方案1】：

或者您可以创建搜索栏的出口并执行以下操作：-

@IBOutlet weak var searchBar: UISearchBar!
searchBar.barTintColor = UIColor.black;

或者你想创建自定义然后：-

var searchBar: UIView = UIView()
var searchField: UISearchBar = UISearchBar();

searchBar.frame = CGRect(x: 0, y: 0, width: xxx, height: xxx)
searchField.barTintColor = UIColor.black;
searchField.frame = CGRect(x: searchBar.frame.origin.x, y: searchBar.frame.origin.y, width: xxx, height: searchBar.frame.height)
searchField.tintColor = UIColor.black
searchBar.addSubview(searchField)
