pulled a dictionary ios

here I try to sort a NSdictionary key and a value I find a method but it does not work.

[detailEvent[@"occurences"] sortUsingSelector : @selector(compare:)];

here is the source sorted

"occurences": [
    {
      "jour": "2014-07-27T00:00:00.000Z",
      "hour_start": "11:00:00",
      "hour_end": "18:00:00"
    },
    {
      "jour": "2014-07-26T00:00:00.000Z",
      "hour_start": "11:00:00",
      "hour_end": "18:00:00"
    },
    {
      "jour": "2014-07-25T00:00:00.000Z",
      "hour_start": "11:00:00",
      "hour_end": "18:00:00"
    }

I do not add all because it is very long

I want sorted by date so the key jour

is that there is another method to sort the dictionary?

thanks

I believe that this will sort the dictionaries correctly 

    NSArray *sorted = [detailEvent[@"occurences"] sortedArrayUsingComparator:^NSComparisonResult(NSDictionary *d1, NSDictionary *d2)
    {
        NSString *s1 = d1[@"jour"];
        NSString *s2 = d2[@"jour"];

        return( [s1 compare:s2] );
    }];

If you want them sorted so the most recent date is first, then change the order of the compare

        return( [s2 compare:s1] );
