Use NSPredicate. See the example given below...

NSString *searchString = @"loginStatus";
NSString *regexString = @"[a-z0-9_.%][email protected][a-z0-9_.%]+\\.[a-z][a-z][a-z]";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self matches %@", regexString];
BOOL isStringValid = [predicate evaluateWithObject:searchString];
