xcode: NSArray slice method?

Question

How can I create a NSSet or NSArray X with first 5 elements of NSArray or NSSet Y?

Answer 1

NSArray *X = [NSArray arrayWithObjects:@"foo", @"bar", @"test", @"blah", @"yeah", @"lost", nil];    
NSArray *Y = [X subarrayWithRange:NSMakeRange(0,5)];

The resulting array Y will contain the first five elements of the first array X.
