Details:

'CONTAINS' works:

    NSString *string = @"AABBBAA";
    p = [NSPredicate predicateWithFormat: @"%@ CONTAINS %@", @"AABBBAA",
@"BBB"];
    UKTrue([p evaluateWithObject: string]);

But 'IN' fails:

    NSString *string = @"AABBBAA";
    p = [NSPredicate predicateWithFormat: @"%@ IN %@", @"BBB", @"AABBBAA"];
    UKTrue([p evaluateWithObject: string]);

Here is the description of 'IN' for Cocoa:

NSInPredicateOperatorType

    A predicate to determine if the left hand side is in the right hand
side.

    For strings, returns YES if the left hand side is a substring of the
right hand side . For collections, returns YES if the left hand side is in
the right hand side .

    Available in Mac OS X v10.4 and later.
