searchBarCancelButtonClicked delegate method is not called. Is there any way to call?

Question

UIViewController to implement a view to placing an UITableView UISearchBar and being implemented. But you can not call searchBarCancelButtonClicked. Do not know what the reason.

Answer 1

The reason why searchBarCancelButtonClicked does not fire may be because your UISearchBar does not show the Cancel button. You can display the Cancel button like this:

searchBar.showsCancelButton = true 

I had the same problem and making the Cancel button show made searchBarCancelButtonClicked fire as expected.

Answer 2

Ensure that your UIViewController is set as the delegate of your UISearchBar, and that it adopts the UISearchBarDelegate protocol.
