How to group UITableView with section mentioned in JSON value - ios

Question

I get this json from web service and I need to group it depending on "PRICELISTCATEGORY" value. I tried the following code, but I get repeated rows and sections in the table. I collect the web service array in self.arrayPriceList. What am I doing wrong?
After collecting the array from json web service, I call [self didReceiveResponseJson:self.arrayPriceList];
-(NSMutableDictionary *)priceListCategoryDitionaryAllReadyExist:(NSString *)price {
for(NSMutableDictionary *priceListDict in self.arrayPriceList){
if([[[priceListDict objectForKey:#"PRICELISTCATEGORY"] objectForKey:#"text"] isEqualToString:price])
//return the existing array refrence to add
return priceListDict;
}
// if we dont found then we will come here and return nil
return nil;
}
-(void)didReceiveResponseJson:(NSMutableArray *)jsonArray {
for(NSDictionary *priceDict in jsonArray) {
NSMutableDictionary *existingPriceListDict=[self priceListCategoryDitionaryAllReadyExist:[[priceDict objectForKey:#"PRICELISTCATEGORY"] objectForKey:#"text"]];
NSMutableArray *existingTempArray = [NSMutableArray array];
if(existingPriceListDict != nil) {
//if name exist add in existing array....
[existingTempArray addObject:priceDict];
}
else {
// create new price list array
NSMutableArray *newPriceListArray=[[NSMutableArray alloc] init];
// Add name dictionary in it
[newPriceListArray addObject:priceDict];
// add this newly created pricelist array in globalNameArray
[self.arrayPriceList addObject:newPriceListArray];
}
}
//so at the end print global array you will get dynamic array with the there respetive dict.
//NSLog(#"Table array %#", self.arrayPriceList);

After calling didReceiveResponseJson in viewDidLoad
self.arrayPriceList = [NSMutableArray array];
self.dictPriceList = [NSMutableDictionary dictionary];
I made changes in tableview datasource methods
-(void)didReceiveResponseJson:(NSMutableArray *)jsonArray {
for (NSDictionary *dict in jsonArray ) {
NSString *strPriceListCategory = [[dict objectForKey:#"PRICELISTCATEGORY"] objectForKey:#"text"];
if ([[self.dictPriceList allKeys] containsObject:strPriceListCategory]) {
NSMutableArray *arrayTemp = [self.dictPriceList objectForKey:strPriceListCategory];
[arrayTemp addObject:dict];
[self.dictPriceList setObject:arrayTemp forKey:strPriceListCategory];
} else {
NSMutableArray *arrayTemp = [[NSMutableArray alloc] initWithObjects:dict, nil];
[self.dictPriceList setObject:arrayTemp forKey:strPriceListCategory];
}
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
TGAPriceListCell *cell = [tableView dequeueReusableCellWithIdentifier:#"TGAPriceListCellId" forIndexPath:indexPath];
NSDictionary *dict;
if (self.isFiltered) {
dict = [self.arrayFilteredPriceList objectAtIndex:indexPath.row];
} else {
NSArray *arrayPriceListAllKeys = [self.dictPriceList allKeys];
NSArray *arrayPrice = [self.dictPriceList objectForKey:[arrayPriceListAllKeys objectAtIndex:indexPath.section]];
dict = [arrayPrice objectAtIndex:indexPath.row];
}
cell.lblAPNBarCode.text = [[dict objectForKey:#"APNBARCODE"] objectForKey:#"text"];
cell.lblAvgCost.text = [[dict objectForKey:#"AVERAGECOST"] objectForKey:#"text"];
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (self.isFiltered) {
return self.arrayFilteredPriceList.count;
} else {
NSArray *arrayPriceListAllKeys = [self.dictPriceList allKeys];
NSArray *arrayPrice = [self.dictPriceList objectForKey:[arrayPriceListAllKeys objectAtIndex:section]];
return [arrayPrice count];
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [[self.dictPriceList allKeys] count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *price = [[self.dictPriceList allKeys] objectAtIndex:section];
return price;
}
