Sorting NSArray and returning NSArray?

Question

I am just looking at sorting an NSArray of NSNumbers into numeric order but am a little unsure of the best way to go. By my way of thinking 001 and 002

Answer 1

You don't need a mutable array at all. You can just do:

NSArray* sortedArray = [arrayNumbers sortedArrayUsingSelector:@selector(compare:)];

Answer 2

NSArray* sortedArray = [arrayNumbers sortedArrayUsingSelector:@selector(compare:)];

Answer 3

I think you can just call

return [arrayNumbers sortedArrayUsingSelector:@selector(compare:)];
