UISearchBar : searchBarSearchButtonClicked delegate is not called

Question

In my case, I would restrict search bar text up to 50 characters. So I used shouldChangeTextInRange

- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
return [searchBar.text length] + [text length] - range.length >= 50);
}

But searchBarSearchButtonClicked is not called when search bar text more than 50 characters.

How do I handle this?

Answer 1

do like

- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
   return ([searchBar.text length] + [text length] - range.length > 50) ? NO : YES;
}

Edit:

- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
   return ([searchBar.text length] + [text length] - range.length <= 50);
}

at the same time check

1.You will need to implement the UISearchBarDelegate protocol inside your view controller.

@interface ViewController : UIViewController <UISearchBarDelegate>

2. You will need to assign the delegate

searchBar.delegate = self;

for additional reference
