문제
Just a quick question regarding sets in Obj-c. Given two sets:
NSMutableSet* a = [NSMutableSet setWithObjects: 1, 2, 3, nil];
NSMutableSet* b = [NSMutableSet setWithObjects: 3, 4, 5, nil];
is there a quick and easy way to determine if any element in set A is also in set B?
Something like ...
if ([a contains:[b allObjects]])
// do something
