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

Question

Answer 1

You can use the runtime API to access the cancel button.

UIButton *btnCancel = [self.searchBar valueForKey:@"_cancelButton"];
[btnCancel setEnabled:YES];

As far as your question is concerned, there is no way you can enable the cancel button when the keyboard is dismissed, like there is no callback as such.
