Answer 1

if the SearchBar is in the navigationBar, the code will be different than the usual answer; You need to search for NavigationBar's subviews instead.

-(void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller{
UINavigationBar * navigationBar =  self.navigationController.navigationBar;

for (UIView *subView in navigationBar.subviews){
    if([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]){
        [(UIButton*)subView setTitle:@"İptal" forState:UIControlStateNormal];
    }
}}

and This work in iOS7+ , if you still can't set the title you should learn view debugging - This is how I solved this problem of mine.

This brief tutorial outlines the key points of View-Debugging very well:

    if #available(iOS 13.0, *) {
        controller.searchBar.setValue("Done", forKey:"cancelButtonText")
    } else {
        controller.searchBar.setValue("Done", forKey:"_cancelButtonText")
    }

If you just want to localized the default "Cancel" title for cancel button, I prefer to change the value of CFBundleDevelopmentRegion key from en to your localized region in Info.plist file in project.

Here is my change,

<key>CFBundleDevelopmentRegion</key>
<string>zh_CN</string>

after that, the default "Cancel" title will show as Chinese "取消". This change will also affect all the default region values, for example, the pasteboard operations' action titles on UITextField/UITextView will be localized, "Select" -> "选择", "Paste" -> "粘贴"...

By the way, the Info.plist file could be localized perfectly.

Enjoy!
