How do you keep the cancel button in the search bar enabled when the keyboard is dismissed?

Question

Answer 1

Call to [self.searchBar resignFirstResponder] will make the cancel button disabled. Hence, you should always update cancel button to enable after calling it.

Objective-C

[searchBar resignFirstResponder];
UIButton *cancelButton = (UIButton *)[searchBar valueForKey:@"cancelButton"];
[cancelButton setEnabled:YES];

Swift

searchBar.resignFirstResponder()
if let cancelButton = searchBar.value(forKey: "cancelButton") as? UIButton
    cancelButton.isEnabled = true
}

In my experience, view.endEditing(true) is the problem. Because it's also called .resignFirstResponder if there's a UITextField inside the view, which is contained in UISearchBar.
