How do I sort an NSMutableArray with custom objects in it?

Question

What I want to do seems pretty simple, but I can\'t find any answers on the web. I have an NSMutableArray of objects, and let\'s say they are \'Person\' objects

Sorting NSMutableArray is very simple:

NSMutableArray *arrayToFilter =
     [[NSMutableArray arrayWithObjects:@"Photoshop",
                                       @"Flex",
                                       @"AIR",
                                       @"Flash",
                                       @"Acrobat", nil] autorelease];

NSMutableArray *productsToRemove = [[NSMutableArray array] autorelease];

for (NSString *products in arrayToFilter) {
    if (fliterText &&
        [products rangeOfString:fliterText
                        options:NSLiteralSearch|NSCaseInsensitiveSearch].length == 0)

        [productsToRemove addObject:products];
}
[arrayToFilter removeObjectsInArray:productsToRemove];
