Parse json for sectioned UITableView in iOS - ios

Question

I am trying to display State (in section title) and City (in table rows) from this url. Top Cities will come in first section followed by state and cities. Issue is I am not able to assign respective array of cities for sectioned state title row. Here's what I tried..
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSLog(#"Json dictionary = %#", json);
self.dictListSateMaster = [json objectForKey:#"RaffleInstanceLocations"];
for (NSDictionary *dict in [self.dictListSateMaster objectForKey:#"listStateMaster"])
{
ViewLocationsObjct *viewLocationsObjct = [[ViewLocationsObjct alloc] init];
viewLocationsObjct.StateNameStr = [dict objectForKey:#"StateName"];
[self.arrayListStateMaster addObject:[dict objectForKey:#"StateName"]];
for (NSDictionary *dictnry in [dict objectForKey:#"listCityMaster"])
{
//*********-- Need corrections here
ViewLocationStateMaster *viewLocNewObjct = [[ViewLocationStateMaster alloc] init];
viewLocNewObjct.CityName = [dictnry objectForKey:#"CityName"];
[self.arrayListCityMaster addObject:viewLocNewObjct];
}
}
for (NSDictionary *dict in [self.dictListSateMaster objectForKey:#"listTopCities"])
{
ViewLocationsObjct *viewLocationsObjct = [[ViewLocationsObjct alloc] init];
viewLocationsObjct.CityName = [dict objectForKey:#"CityName"];
[self.arrayTopCities addObject:viewLocationsObjct];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return self.arrayListStateMaster.count+1; //+1 to append to top cities section at the top
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellId = #"cellId";
ViewLocationsTblCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId forIndexPath:indexPath];
if (indexPath.section == 0)
{
ViewLocationsObjct *viewLocationObj = [self.arrayTopCities objectAtIndex:indexPath.row];
cell.locationLabl.text = viewLocationObj.CityName;
}
else
{
//*********-- Need corrections here
//NSString *sectionTitle = [self.arrayListStateMaster objectAtIndex:indexPath.section];
//NSMutableArray *arrayCities = [self.dictListSateMaster objectForKey:sectionTitle];
//cell.locationLabl.text = [arrayCities objectAtIndex:indexPath.row];
ViewLocationStateMaster *viewLoc = [self.arrayListCityMaster objectAtIndex:indexPath.row];
cell.locationLabl.text = viewLoc.CityName;
}
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (section == 0)//return top cities for 1st section
{
return self.arrayTopCities.count;
}
else
{
return self.arrayListCityMaster.count;
}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
if (section == 0)
{
return #"Top Cities";
}
else
{
if (self.arrayListStateMaster.count > 0)
{
return [self.arrayListStateMaster objectAtIndex:section-1];//-1 to remove index of top cities section at the top
}
else
{
return #"";
}
}
}

OK so here's how my problem was solved !
NSDictionary *dictRaffleInstLocations = [json objectForKey:#"RaffleInstanceLocations"];
sectionArray = [dictRaffleInstLocations objectForKey:#"listStateMaster"];
topCityArray = [dictRaffleInstLocations objectForKeyedSubscript:#"listTopCities"];
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (section == 0) {
return topCityArray.count;
}else
return [[[sectionArray objectAtIndex:section-1]objectForKey:#"listCityMaster"] count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return sectionArray.count+1;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
if (section == 0) {
return #"Top Cities";
}else
return [[sectionArray objectAtIndex:section-1]objectForKey:#"StateName"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellId = #"MyCellLocation";
ViewLocationsTblCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId forIndexPath:indexPath];
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0f)
{
cell.layoutMargins = UIEdgeInsetsZero;
cell.preservesSuperviewLayoutMargins = NO;
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
NSString *titleString = #"";
if (indexPath.section == 0) {
titleString = [[topCityArray objectAtIndex:indexPath.row]objectForKey:#"CityName"];
}else{
NSArray *cityArray = [sectionArray[indexPath.section-1]objectForKey:#"listCityMaster"];
titleString = [cityArray[indexPath.row]objectForKey:#"CityName"];
}
cell.locationLabl.text = titleString;
return cell;
}
