Sort an NSArray in Descending Order

Question

I have an NSArray of NSNumber objects that I have successfully sorted in ascending order using the following:

[myArray sortedArrayU         


        

Answer 1

Another way, imo, is also nice: write another reverseCompare with category:

@implementation NSNumber (Utility)

- (NSComparisonResult)reverseCompare:(NSNumber *)aNumber {
  return [aNumber compare:self];
}

The good thing is that you can reuse everywhere and don't have to write the loop with reverse iterate. The bad thing is that you have to write more code:)
