UISearchController change 'Cancel' button

Question

How we can change the title of cancel button in search controller?

Answer 1

You also need to have the searchBar setShowsCancelButton before the procedure.

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
    [theSearchBar setShowsCancelButton:YES animated:NO];
    for (UIView *subView in theSearchBar.subviews){
        if([subView isKindOfClass:[UIButton class]]){
            [(UIButton*)subView setTitle:@"Done" forState:UIControlStateNormal];
        }
    }
}

Note also use UIButton to avoid problems with Apple!

Answer 2

Worth noting, that the preferred method for changing the Cancel button title is now via appearances (got the idea from an another question: https://stackoverflow.com/a/34522163/511878):

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

Answer 3

  class ViewController: UIViewController,UISearchResultsUpdating {
        func updateSearchResults(for searchController: UISearchController) {
            //write your code here
        }
        @IBOutlet weak var navItem: UINavigationItem!
        let searchController = UISearchController(searchResultsController: nil)
        override func viewDidLoad() {
            super.viewDidLoad()
            searchController.obscuresBackgroundDuringPresentation = false
            searchController.definesPresentationContext = true
            searchController.searchResultsUpdater = self
            if #available(iOS 11.0, *){
                navigationItem.searchController = searchController
                UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).title = "new title"
            }
            // Do any additional setup after loading the view.
        }
    }

Answer 4

The solution provided above could change with new iOS releases. Here is a better approach:

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

Answer 5

The Swift equivalent of Burhanuddin Sunelwala answer did the trick for me!

self.searchBar.setValue("custom string", forKey: "cancelButtonText")

Thanks to Burhanuddin Sunelwala for putting me in the right direction!

Answer 6

for (UIView *subView in SearchBar.subviews) {
    if ([subView isKindOfClass:[UIButton class]]) {
        UIButton *cancelButton = (UIButton*)subView;

        [cancelButton setTitle:@"TitleString" forState:UIControlStateNormal];
}
