I'm parsing data from JSON
webservice and then using the following code to sort the data by price, date, discount etc.
here's the code I'm using to sort the data:
-(void)priceSort:(id)sender {
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
initWithKey: @"price" ascending: YES];
NSMutableArray *sortedArray = (NSMutableArray *)[self.displayItems
sortedArrayUsingDescriptors: [NSArray arrayWithObject:sortDescriptor]];
[self setDisplayItems:sortedArray];
[self.tableView reloadData];
}
this works fine when I'm trying to sort by price, however when I want to sort by number of reviews I can't seem to get the code right:
for price I use:
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
initWithKey: @"price" ascending: YES];
but for reviews I want to get the "n" value. see how it's nested in the output (of the display Items mutableArray below:
"old_price" = 24;
price = "9.9";
reviews = {
**n = 11;**
val = 70;
};
"sold_count" = 101;
thanks for any help on this :)
To sort by the number of reviews n
, your sort descriptor would be:
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
initWithKey: @"reviews.n" ascending: YES];
