Answer 1

You can use NSSet. From Apple’s doc: NSSet declares the programmatic interface for static sets of distinct objects. Like so:

NSSet *mySet = [NSSet setWithArray:array];

Or:

NSSet *mySet = [NSSet alloc]initWithArray:array];

(Edited for completeness) And then:

array = [mySet allObjects]; //now you can continue using the array as previously
