Hide UISearchBar Cancel Button

Question

I have a UISearchDisplayController and UISearchBar hooked up to my ViewController via Outlets from my nib.

I\'d like to hide the cancel button so that the user never

Answer 1

If the cancel button shows up when editing the search field of the search bar you could do the following; subclass the search bar and have it implement the UITextFieldDelegateprotocol:

@interface CustomAlignedSearchBar : UISearchBar<UITextFieldDelegate>

Then implement textFieldDidBeginEditing: and do something like:

- (void)textFieldDidBeginEditing:(UITextField *)textField{
    [self setShowsCancelButton:self.cancelButtonShown animated:NO];
}

This will make sure that the cancel button will not show up.

class CustomSearchBar: UISearchBar {

    override func setShowsCancelButton(showsCancelButton: Bool, animated: Bool) {
        super.setShowsCancelButton(false, animated: false)
    }

}

class CustomSearchController: UISearchController, UISearchBarDelegate {

    lazy var _searchBar: CustomSearchBar = {
        [unowned self] in
        let customSearchBar = CustomSearchBar(frame: CGRectZero)
        customSearchBar.delegate = self
        return customSearchBar
    }()

    override var searchBar: UISearchBar {
        get {
            return _searchBar
        }
    }

}

I had the same issue, but fixed it a different way.

For those who can't or don't want to subclass UISearchDisplayController, I fixed the issue by adding a listener on UIKeyboardWillShowNotification, and setting [self setShowsCancelButton:NO animated:NO] there.

In viewWillAppear::

// Add keyboard observer:
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWillAppear:)
                                             name:UIKeyboardWillShowNotification
                                           object:nil];

Then you create:

- (void)keyboardWillAppear:(NSNotification *)notification
{
    [YOUR-SEARCHBAR-HERE setShowsCancelButton:NO animated:NO];
}

Don't forget to add,

[[NSNotificationCenter defaultCenter] removeObserver:self];

in viewWillDisappear:!

Hope this helps!

On iOS 13.0 and later, UISearchController has this property you can use:

@property (nonatomic) BOOL automaticallyShowsCancelButton API_AVAILABLE(ios(13.0)); // Default YES

This seems to be a bug within Xcode. I submitted this error to Apple's bug reporting site, and they've followed up asking for more sample code and use-cases.

Thanks everyone for your attempt at solving this problem.
