NSScanner problems

I'm having a few more problems that I need to figure out, if someone
can help me out.

I'm trying to use an NSScanner to scan a string and see if it contains
a substring.  I have an array of strings that I want to search for in
each string, and if any of them are present, then I want to set a flag.

Here's the code:

    NSScanner *scanner;
    NSMutableArray *arrayOfValues = [[NSUserDefaults
standardUserDefaults] objectForKey:@"User-Defined Values"];
    int i;
    int j;
    BOOL flag = NO;
    for (i=0; i < [processArray count]; i++) {
    scanner = [NSScanner scannerWithString:[[processArray
objectAtIndex:i] processName]];
        for (j=0; j < [arrayOfValues count]; j++) {
            NSLog(@"%@",[[processArray objectAtIndex:i] processName]);
            NSLog(@"%@",[arrayOfValues objectAtIndex:j]);
            if ([scanner scanString:[arrayOfValues objectAtIndex:j]
intoString:nil]) { flag = YES; }
     if (flag) {NSLog(@"YES!");}
        }
    }

The problem is, the NSScanner returns sets the flag as YES for each
step.  That is, every time the log displays the processName and the
scanString, it always returns a YES, regardless of whether processName
actually contains scanString or not.

Am I doing something wrong here?

Thanks for any help.
