UISearchBarSearchField BackgroundView color
我正在尝试更改搜索栏文本字段的背景颜色,我已经搜索并尝试了很多解决方案,但这些都不起作用。
所以,请任何人告诉我确切的解决方案。我们如何更改搜索栏文本字段的背景颜色?
/// used to prepare searchController inside navigation.
private func prepareNavigationSearchControllerSetup() {
self.title = AppConstant.kContacts
let search = UISearchController(searchResultsController: nil)
search.searchResultsUpdater = self
search.searchBar.cornerRadius = 10.0
search.searchBar.textField?.backgroundColor = .red
search.searchBar.textField?.tintColor = .yellow
self.navigationItem.searchController = search
self.navigationItem.hidesSearchBarWhenScrolling = false
}
extension UISearchBar {
var textField: UITextField? {
let subViews = subviews.flatMap { [=10=].subviews }
return (subViews.filter { [=10=] is UITextField }).first as? UITextField
}
}
你可以试试这个
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).backgroundColor = .yellow
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).tintColor = .blue
输出
Edit : Full Code
var searchController = UISearchController()
let resultsTableController = Storyboard.Home.instantiateViewController(withIdentifier: "GlobalTableVC") as! GlobalTableVC
resultsTableController.tableView.delegate = self
resultsTableController.tableView.dataSource = self
resultsTableController.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "SearchCell")
searchController = UISearchController(searchResultsController: resultsTableController)
searchController.searchBar.placeholder = "Search"
searchController.dimsBackgroundDuringPresentation = true
searchController.searchBar.sizeToFit()
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.keyboardType = UIKeyboardType.alphabet
searchController.searchBar.tintColor = UIColor.white
searchController.searchBar.barTintColor = UIColor(hexString: "EB033B")
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).backgroundColor = .yellow
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).tintColor = .blue
searchController.searchBar.delegate = self
searchController.delegate = self
searchController.searchResultsUpdater = self
present(searchController, animated: true, completion: nil)
经过更多的搜索,我找到了适合我的正确答案。
