Change UISearchBar/Keyboard Search Button Title

Question

In the UISearchBar control, is the a way to change the Search key title for the keyboard to Done?

Answer 1

For a searchbar named tablesearchbar:

// Set the return key and keyboard appearance of the search bar
        for (UIView *searchBarSubview in [tableSearchBar subviews]) {

            if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)]) {

                @try {

                    [(UITextField *)searchBarSubview setReturnKeyType:UIReturnKeyDone];
                    [(UITextField *)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
                }
                @catch (NSException * e) {

                    // ignore exception
                }
            }
        }

Answer 2

At least for iOS 8, simply:

    [self.searchBar setReturnKeyType:UIReturnKeyDone];

Answer 3

As of iOS 7 beta 5, Run Loop's answer didn't work for me, but this did:

for(UIView *subView in [searchBar subviews]) {
    if([subView conformsToProtocol:@protocol(UITextInputTraits)]) {
         [(UITextField *)subView setReturnKeyType: UIReturnKeyDone];
    } else {
        for(UIView *subSubView in [subView subviews]) {
            if([subSubView conformsToProtocol:@protocol(UITextInputTraits)]) {
                [(UITextField *)subSubView setReturnKeyType: UIReturnKeyDone];
            }
        }      
    }
}
