"location_name" = "<null>";
"pre_fixied" = "$3.00";

zone = "Zone 3";
"zone_id" = 31;
},
{
"location_id" = 458;
"location_name" = "Eden Hills";
"pre_fixied" = "$5.00";
"state_name" = Adelaide;
status = 1;
zone = "Zone 3";
"zone_id" = 31;

"location_id" = 457;
"location_name" = Glengowrie;
"pre_fixied" = "$5.00";
"state_name" = Adelaide;
status = 1;
zone = "Zone 3";
"zone_id" = 31;
}
);
message = "List of Location";
status = Success;
}
its appearing by location id descending order i want this json by location name ascending order.
I have sort location list array separately but i want whole json and locationlist by locationname order

Answer 1

try this
locationDescriptor = [[NSSortDescriptor alloc] initWithKey:#"location_id" ascending:YES];
sortDescriptors = [NSArray arrayWithObject: locationDescriptor];
sortedArray = [myArray sortedArrayUsingDescriptors:sortDescriptors];
Now change sortedArray into any other format as required.

Answer 2

First short Location Array.
lets say your json result is NSDictionary *jsonResult; And filtered array is NSArray *filteredArray;
Then
NSMutableDictionary *filteredJson = [NSMutableDictionary new];
[filteredJson setObject:[jsonResult valueForKey:#"Description"] forKey:#"Description"];
[filteredJson setObject:[jsonResult valueForKey:#"code"] forKey:#"code"];
[filteredJson setObject:filteredArray forKey:#"locationList"];
[filteredJson setObject:[jsonResult valueForKey:#"message"] forKey:#"message"];
[filteredJson setObject:[jsonResult valueForKey:#"status"] forKey:#"status"];
