在iOS 8中更改UISearchBar取消按钮文本

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

Objective-C的:

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

迅速:

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

找到了!.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:

在你的AppDelegate中添加:

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.Check的子类,用于View作为UIButton,如果是,则更改UIButton的属性.

Answer 6

对于 iOS 13 支持：

迅速：

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

目标 C：

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

Answer 7

在Swift中:

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

基于Burhanuddin Sunelwala的回答.

Answer 8

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,但第二次显示.

直到我看到@ polo987的答案.这就是我所做的工作:

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

Answer 9

在Swift4中

更改标题:

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

换颜色:

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