Change UISearchBar/Keyboard Search Button Title in

Question

I'm trying to do the equivalent of this but in Swift and I'm running into problems:

1. No equivalent of try/catch blocks in swift
2. The if statement never seems to be evaluated as true

Here is what I've put together so far:

for searchBarSubview in self.searchBar!.subviews {
    if (searchBarSubview.conformsToProtocol(UITextInputTraits)) {
        var searchBarTextField = searchBarSubview as UITextField
        searchBarTextField.returnKeyType = UIReturnKeyType.Done
    }
}

Does anyone have any ideas where I'm going wrong?

Answer 1

To change return type of UISearchBar in swift

searchBar.returnKeyType = UIReturnKeyType.Done

Other Enum

    case Default
    case Go
    case Google
    case Join
    case Next
    case Route
    case Search
    case Send
    case Yahoo
    case Done
    case EmergencyCall
    @available(iOS 9.0, *)
    case Continue

Answer 2

I think you only need to do the following code and you are good to go. Any reasons why that bothers you to check UITextInputTraits?

[self.searchBar setReturnKeyType:UIReturnKeyDone];
