UISearchBar Cancel Button

uisearchbar

Using a UISearchBar with showCancelButton=YES on iOS 5. Would like the cancel button to stay enabled when the keyboard drops down. Using the following code seems not to work:

    for (id subView in self.searchControl.subviews)
    {
        if ([subView isKindOfClass:[UIButton class]])
        {
            UIButton *cancelButton = (UIButton *)subView;
            [cancelButton setEnabled:YES];
            break;
        }         
    }

The subView is actually a UINavigationButton which appears not to be subclassed off of UIButton. What am I missing here??????? Also cannot find any info on the UINavigationButton class in the Apple docs.

Set your searchbar delegate and than put this code. 

- (void) searchBarSearchButtonClicked:(UISearchBar*) theSearchBar
  {
     [theSearchBar resignFirstResponder];
     [theSearchBar setShowsCancelButton:NO animated:YES];
  }
 - (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
  {
     [searchBar setShowsCancelButton:YES animated:YES];
  }
  - (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
  {
     [searchBar resignFirstResponder];
     [searchBar setShowsCancelButton:NO animated:YES];
  }

Swift 3.0

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
     searchBar.resignFirstResponder()
     searchBar.setShowsCancelButton(false, animated: true)
}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
     searchBar.setShowsCancelButton(true, animated: true)
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
     searchBar.resignFirstResponder()
     searchBar.setShowsCancelButton(false, animated: true)
}
