    With the help of following code you can sort the given dictionary containing key as Date.

    @implementation NSMutableDictionary (SortingNSMutableDictionary)

-(NSArray *)getAllSortedKeys{
    NSMutableArray *array = [NSMutableArray arrayWithArray:[self allKeys]];
        [array sortUsingComparator: (NSComparator)^(NSString *a, NSString *b)
         {

        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

         [dateFormatter setDateFormat:@"MMMM yyyy"];
         NSDate *date1 = [dateFormatter dateFromString:a];
         NSDate *date2 = [dateFormatter dateFromString:b];
         return [date2 compare:date1];

     }
     ];



    return array;
}
