Swift 4 version:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool{
    if var text = textField.text, range.location == text.count, string == " " {
        let noBreakSpace: Character = "\u{00a0}"
        text.append(noBreakSpace)
        textField.text = text
        return false
    }
    return true
}
