I don't think you'll need regular expressions for that. Just do this:

NSString* email = @"[email protected]";
NSArray * components = [email componentsSeparatedByString:@"@"];
NSString* username = (NSString *)[components objectAtIndex:0];

you alsa can do:

NSString* email = @"[email protected]";
NSString* username = [email substringToIndex:[email rangeOfString:@"@"].location];
