This will work

这将工作

斯威夫特版本:

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

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

发现它!在ios8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)

}

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中没有尝试过，但是应该这样做，注意不要在应用周期的早期放置这条线(例如:appDelegate)

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

and as of ios9 you could also use

而ios9也可以用

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

Swift version:

斯威夫特版本:

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

Hope that helps ;)

希望帮助。

斯威夫特3.0:

In your AppDelegate add this:

在AppDelegate中添加如下内容:

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

 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])。子视图包含UISearchBarBackground、UISearchBarTextField UINavigationButto‌UIButton的n UINavigationButton的子类。检查视图为UIButton，如果是，那么改变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UISearchBar中工作在UISearchController中。文本在第一次显示取消按钮时没有改变，但在第二次时改变了。

That is until I saw @polo987's answer. Here's what I did that worked:

直到我看到了@polo987的答案。我所做的是:

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

I have added titleLabel.font to the mix...

我有添加titleLabel。字体的组合…

This goes straight into my ViewDidLoad() {

这直接进入了我的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

I know this may seem to be a bit irrelevant but in my opinion this is safer than using private apis and more efficient than taking a dive into the unknown views. This solution makes sense only if you have your own localisation engine and you do want Apple to follow your mechanism all over the app. Basically my idea is to switch the language the iOS SDK uses to localise the button by altering the "AppleLanguages" key in the NSUserDefaults. You can go here for more information about how this works.

我知道这似乎有点无关紧要，但在我看来，这比使用私有api更安全，也比深入研究未知视图更有效。这个解决方案只有在你有自己的本地化引擎的情况下才有意义，而且你希望苹果在整个应用程序中都遵循你的机制。基本上，我的想法是通过修改NSUserDefaults中的“AppleLanguages”键来切换iOS SDK用于本地化按钮的语言。你可以到这里获取更多关于它是如何工作的信息。

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

Put this code to use the English localisation and a French fallback no matter what language is set on the phone. This only takes effect within the app.

将此代码用于使用英语本地化和法语后备，无论在电话上设置什么语言。这只会在应用中生效。

Here is Swift solution:

这是迅速的解决方案:

for (view) in _searchController.searchBar.subviews {
    for (subview) in view.subviews {
        if (subview.isKindOfClass(UIButton.self)) {
            let cancelButton = subview as! UIButton
            cancelButton.setTitle("BlaBla", forState: .Normal)
            break
        }
    }
}
