Question

我想在iOS 8中的UISearchBar中的“取消”按钮的“取消”中更改文本。我正在使用UISearchController。我尝试过iOS 6和iOS 7的不同方法，但它们不起作用。有人这样做过吗？

Answer 1

<强>目标-C：

[searchBar setValue:@"customString" forKey:@"_cancelButtonText"];

<强>夫特：

searchBar.setValue("customString", forKey:"_cancelButtonText")

Answer 2

这在ios8中对我有用，没有在ios7中尝试，但是应该这样做，小心在应用程序周期的早期放置这一行（例如：appDelegate）

[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitle:@"Annuler"];

从ios9开始，你也可以使用

[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitle:@"Annuler"];

Swift版本：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "Annuler"

希望有所帮助;）

Answer 3

找到它！在iOS 8中，取消按钮位于“cancelButton”键下。我使用UISearchBar委托searchBarTextDidBeginEditing进行更改。

func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
    let uiButton = searchBar.valueForKey("cancelButton") as UIButton
    uiButton.setTitle("Done", forState: UIControlState.Normal)

}

Answer 4

Swift 3.0：

在 AppDelegate 中添加以下内容：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "my text"

Answer 5

 for view in (UISearchBar.subviews[0]).subviews{
             if let button = view as? UIButton{
             button.setTitleColor(UIColor.whiteColor(), forState: .Normal)
             button.setTitle("Cancel", forState:.Normal)
            }
     }

self.subviews [0]）。子视图包含UISearchBarBackground，UISearchBarTextField，UINavigationButto n，其中UINavigationButton是UIButton的子类。查看为UIButton的视图，如果是，则更改UIButton的属性。

Answer 6

我无法在UISearchController中为UISearchBar工作。第一次显示取消按钮时，文本没有改变，但第二次是第二次。

直到我看到@ polo987的回答。这就是我所做的工作：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "Done"

Answer 7

在 Swift4

中

更改标题：

(searchBar.value(forKey: "cancelButton") as! UIButton).setTitle("Done", for: .normal)

更改颜色：

(searchBar.value(forKey: "cancelButton") as! UIButton).setTitleColor(UIColor.blue, for: .normal)

Answer 8

在斯威夫特：

searchBar.setValue("customString", forKey: "_cancelButtonText")

基于Burhanuddin Sunelwala回答。

Answer 9

对于iOS 13支持：

快捷键：

    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "Whatever"

目标C：

    [[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:[NSArray arrayWithObject:[UISearchBar class]]] setTitle:@"Whatever"]

Answer 10

我已将titleLabel.font添加到混音......

这直接进入我的ViewDidLoad（）{

        let searchFont = UIFont(name: "BrandonGrotesque-Medium", size: 12)
        let textFieldSearchBar = self.searchBar.valueForKey("searchField") as! UITextField
        textFieldSearchBar.font = searchFont
        let cancelButton = searchBar.valueForKey("cancelButton") as! UIButton
        cancelButton.setTitle("Done", forState: .Normal)
        cancelButton.titleLabel!.font = searchFont

Answer 11

我知道这似乎有点无关紧要，但在我看来，这比使用私人api更安全，而且比潜入未知视图更有效率。只有当您拥有自己的本地化引擎并且希望Apple在整个应用程序中遵循您的机制时，此解决方案才有意义。基本上我的想法是通过改变NSUserDefaults中的“AppleLanguages”键来切换iOS SDK用于本地化按钮的语言。您可以访问here以获取有关其工作原理的更多信息。

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"en", @"fr", nil] forKey:@"AppleLanguages"];
[[NSUserDefaults standardUserDefaults] synchronize];

无论手机上设置何种语言，都可以使用此代码来使用英语本地化和法语后备。这仅在应用程序中生效。

class SearchBar: UISearchBar {

    private enum SubviewKey: String {
        case searchField, clearButton, cancelButton,  placeholderLabel
    }

    // Button/Icon images
    public var clearButtonImage: UIImage?

    // Button/Icon colors
    public var searchIconColor: UIColor?

    public var capabilityButtonColor: UIColor?

    // Text
    public var textColor: UIColor?
    public var placeholderColor: UIColor?
    public var cancelTitle: String?

    // Cancel button to change the appearance.
    public var cancelButton: UIButton? {
        guard showsCancelButton else { return nil }
        return self.value(forKey: SubviewKey.cancelButton.rawValue) as? UIButton
    }

    override func layoutSubviews() {
        super.layoutSubviews()

        if let cancelColor = cancelButtonColor {
            self.cancelButton?.setTitleColor(cancelColor, for: .normal)
        }
        if let cancelTitle = cancelTitle {
            self.cancelButton?.setTitle(cancelTitle, for: .normal)
        }

        guard let textField = self.value(forKey: SubviewKey.searchField.rawValue) as? UITextField else { return }

        if let clearButton = textField.value(forKey: SubviewKey.clearButton.rawValue) as? UIButton {
            update(button: clearButton, image: clearButtonImage, color: clearButtonColor)
        }
        if let resultsButton = textField.rightView as? UIButton {
            update(button: resultsButton, image: resultsButtonImage, color: capabilityButtonColor)
        }
        if let searchView = textField.leftView as? UIImageView {
            searchView.image = (searchImage ?? searchView.image)?.withRenderingMode(.alwaysTemplate)
            if let color = searchIconColor {
                searchView.tintColor = color
            }
        }
        if let placeholderLabel =  textField.value(forKey: SubviewKey.placeholderLabel.rawValue) as? UILabel,
            let color = placeholderColor {
            placeholderLabel.textColor = color
        }
        if let textColor = textColor  {
            textField.textColor = textColor
        }
    }

    private func update(button: UIButton, image: UIImage?, color: UIColor?) {
        let image = (image ?? button.currentImage)?.withRenderingMode(.alwaysTemplate)
        button.setImage(image, for: .normal)
        button.setImage(image, for: .highlighted)
        if let color = color {
            button.tintColor = color
        }
    }

用法：

class ViewController: UIViewController {

    @IBOutlet private weak var searchBar: SearchBar!

    override func viewDidLoad() {
        super.viewDidLoad()

        searchBar.clearButtonColor      = .purple
        searchBar.cancelButtonColor     = .magenta
        searchBar.searchIconColor       = .red
        searchBar.placeholderColor      = .green
        searchBar.textColor             = .orange
        searchBar.capabilityButtonColor = .green
    }
}
