Change UISearchBar cancel button text in iOS 8
提问by Wilmer
I'd like to change the text from ¨Cancel¨to ¨Done¨ of the Cancel button inside the UISearchBar in iOS 8. I am using UISearchController. I've tried different approaches for iOS 6 and iOS 7 and they do not work. Has anybody done this?
我想将 iOS 8 中 UISearchBar 中取消按钮的“取消”文本更改为“完成”。我正在使用 UISearchController。我为 iOS 6 和 iOS 7 尝试了不同的方法，但它们不起作用。有没有人做过这个？

This worked for me in ios8, did not try in ios7, but should do the trick, beware of placing this line in the early times of the app cycle (eg : appDelegate)
这在 ios8 中对我有用，在 ios7 中没有尝试，但应该可以解决问题，小心将此行放在应用程序周期的早期（例如：appDelegate）
[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitle:@"Annuler"];
and as of ios9 you could also use
从 ios9 开始，您还可以使用
[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitle:@"Annuler"];
Swift version:
迅捷版：
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "Annuler"
Hope that helps ;)
希望有帮助;)

Found it!. in iOS 8, the cancel button is under the key "cancelButton". I used UISearchBar delegate searchBarTextDidBeginEditing to make the change.
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)
}

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]).subviews contain UISearchBarBackground,UISearchBarTextField,UINavigationButto??n in which UINavigationButton is subclass of UIButton.Check for View as UIButton and if yes then change property of UIButton.
self.subviews[0]).subviews 包含 UISearchBarBackground,UISearchBarTextField,UINavigationButto??n，其中 UINavigationButton 是 UIButton 的子类。检查 View 为 UIButton，如果是，则更改 UIButton 的属性。

I was having trouble getting this to work for a UISearchBar within a UISearchController. The text didn't change the first time the cancel button was shown but it did the second time.
我很难让它在 UISearchController 中为 UISearchBar 工作。第一次显示取消按钮时，文本没有改变，但第二次改变了。
That is until I saw @polo987's answer. Here's what I did that worked:
直到我看到@ polo987 的回答。这是我所做的工作：
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "Done"

I have added titleLabel.font to the mix...
我已将 titleLabel.font 添加到组合中...
This goes straight into my ViewDidLoad() {
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
