Change UISearchBar/Keyboard Search Button Title in Swift

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

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];
