iOS10 How can I hide "x" symbol of the searchBar

Question

I can display and hide keyboard. There is a problem: when I tap something in the searchBar, there is a X symbol in the left of the searchBar and a cancel button. If I click cancel button first and then click the X symbol, I will got an fatal error: Index out of range.

So I want to hide the “x” symbol rather than “cancel” button. Is this possible?

Answer 1

Get the textfield and hide it.

UITextField *textField = [searchBar valueForKey:@"_searchField"];
textField.clearButtonMode = UITextFieldViewModeNever;

or Swift you can alwasy extend the search bar and override it.

class NoCancelButtonSearchController: UISearchController {
    let noCancelButtonSearchBar = NoCancelButtonSearchBar()
    override var searchBar: UISearchBar { return noCancelButtonSearchBar }
}

class NoCancelButtonSearchBar: UISearchBar {
    override func setShowsCancelButton(_ showsCancelButton: Bool, animated: Bool) { /* void */ }
}
