## Discussion

Discussion The following example illustrates the use of this method. NSSet *sourceSet =     [NSSet setWithObjects:@"One", @"Two", @"Three", @"Four", nil]; NSPredicate *predicate =     [NSPredicate predicateWithFormat:@"SELF beginswith 'T'"]; NSSet *filteredSet =     [sourceSet filteredSetUsingPredicate:predicate]; // filteredSet contains (Two, Three)
