How to check if string matches a regular expression in objective-c?

Question

since regular exressions are not supported in Cocoa I find RegexKitLite very usefull. But all examples extract matching strings.

I just want to test if a string matches a regular expression and get a Yes or No.

How can I do that?

I've used NSPredicate for that purpose:

NSString *someRegexp = ...; 
NSPredicate *myTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", someRegexp]; 

if ([myTest evaluateWithObject: testString]){
//Matches
}
