currently I have this: @"(\S)+"
, but it just prevents spaces after any full character, so how can I prevent space in the first character as well ?

If you want to make sure there's no whitespace in the string, use this:
^\S+$
^
anchors the match to the beginning of the string.
\S+
matches one or more non-whitespace characters.
$
anchor the match to the end of the string.
If you're really using the NSRegularExpression class in Apple's Objective-C developer framework, it should look like this:
@"^\\S+$"
But if (as I suspect) you're using a C# Regex, it should look like this:
@"^\S+$"
("regex" is the general-purpose tag for regular expressions. I'll just remove that other tag.)
