UIsearchBarinput键盘types
有谁知道如何改变search栏的input键盘types？ 代码
searchController.searchBar.inputView = input 在文本字段中不起作用。 我已经读过searchBar的子视图是一个文本框，但我不知道如何访问该子视图来更改inputView。
我想你想要显示不同的标准键盘，确保你已经分配给键盘。
class ViewController: UIViewController, UISearchBarDelegate, KeyboardDelegate { @IBOutlet weak var searchBar: UISearchBar! override func viewDidLoad() { let keyboardView = KeyboardView(frame: CGRect(x: 0, y: 0, width: 375, height: 165)) keyboardView.delegate = self let searchTextField = searchBar.value(forKey: "_searchField") as! UITextField searchTextField.inputView = keyboardView } func keyWasTapped(text: String) { searchBar.text = text } }
我的自定义键盘类
protocol KeyboardDelegate: class { func keyWasTapped(text: String) } class KeyboardView: UIView { // This variable will be set as the view controller so that // the keyboard can send messages to the view controller. weak var delegate: KeyboardDelegate? // MARK:- keyboard initialization required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) initializeSubviews() } override init(frame: CGRect) { super.init(frame: frame) initializeSubviews() } func initializeSubviews() { let xibFileName = "KeyboardView" // xib extention not included let view = Bundle.main.loadNibNamed(xibFileName, owner: self, options: nil)?[0] as! UIView self.addSubview(view) view.frame = self.bounds } // MARK:- Button actions from .xib file @IBAction func keyTapped(_ sender: UIButton) { // When a button is tapped, send that information to the // delegate (ie, the view controller) self.delegate?.keyWasTapped(text: sender.titleLabel!.text!) // could alternatively send a tag value } }
你必须这样访问：
if let searchBarTxtField = searchController.searchBar.valueForKey("_searchField") as UITextField { searchBarTxtField.inputView = input }
