Does not work for iOS 8
does not work
Doesn't work.
Doesn't work anymore.

The reason why this doesn't work is because now UISearchBar have a UIView that encapsulates its components.
I think this is an unsafe way to detect clear tap in UISearchBar because Apple can change the way UIKit componentes are architected.
doesn't work
this works!
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{
if (searchText.length == 0){
[searchBar performSelector:@selector(resignFirstResponder)
withObject:nil
afterDelay:0];
}
}
@astramex19 code works like a charm ! Thanks !
doesn't work
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
searchBar.searchTextField.delegate = self
}
func textFieldShouldClear(_ textField: UITextField) -> Bool {
print("textFieldShouldClear")
return true
}
