parsing - group array of dictionaries by date from xml in iOS -

here code. please help.

nsdictionary *xmldict = [nsdictionary dictionarywithxmlstring:str]; nsarray *fixtureslist1 = [[xmldict objectforkey:@"matches"] objectforkey:@"ematches"]; nsmutabledictionary *dictionarybydate = [nsmutabledictionary new];  for(nsdictionary *dictionary in fixtureslist1) {     nsstring *datestring = dictionary[@"matchdate"];     nsmutablearray *arraywithsamedate = self.resultssection[datestring];     if(! arraywithsamedate)     {         arraywithsamedate = [nsmutablearray new];         self.resultssection[datestring] = arraywithsamedate;     }     [arraywithsamedate addobject: dictionary]; } //nslog(@"dictionarybydate:%@",self.resultssection); nssortdescriptor *descriptor=[[nssortdescriptor alloc] initwithkey:@"self" ascending:no]; nsarray *descriptors=[nsarray arraywithobject: descriptor]; reverseorder=[[self.resultssection allkeys] sortedarrayusingdescriptors:descriptors]; nslog(@"results:%@",reverseorder);
