Array not being filled (JSON object) - ios

Question

I am trying to ready a JSON output into an array in iOS. But the array is not being filled at all. Here is the relevant code:
- (void) retrieveData;
{
NSString *getDataURL = #"http://localhost:8888/finalproject/ios/getHouseBills.php";
NSURL * url = [NSURL URLWithString:getDataURL];
NSData * data = [NSData dataWithContentsOfURL:url];
jsonArray = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
houseBillsArray = [[NSMutableArray alloc] init];
long test = jsonArray.count;
for(int i = 0; i < jsonArray.count; i++)
{
NSString * hBID = [[jsonArray objectAtIndex:i] objectForKey:#"houseBillID"];
NSString * hID = [[jsonArray objectAtIndex:i] objectForKey:#"houseID"];
NSString * hName = [[jsonArray objectAtIndex:i] objectForKey:#"name"];
NSString * hAmount = [[jsonArray objectAtIndex:i] objectForKey:#"amount"];
NSString * hDate = [[jsonArray objectAtIndex:i] objectForKey:#"date"];
NSString * hAddedBy = [[jsonArray objectAtIndex:i] objectForKey:#"addedBy"];
[houseBillsArray addObject:[[House alloc]initWithHouseBillID:hBID andHouseID: hID andName: hName andAmount: hAmount andDate: hDate andAddedBy: hAddedBy]];
}
[self.tableView reloadData];
[self.refreshControl endRefreshing];
}
Here is an example of the JSON input it will be taking:
[{"houseBillID":"1","houseID":"20","name":"Loo roll","amount":"32453","date":"eqferf","addedBy":"samstone920#googlemail.com"},{"houseBillID":"2","houseID":"20","name":"toothpaste","amount":"3","date":"wefe","addedBy":"44tq"}]
Excuse the fact it is mostly gibberish. But yeah, the array isn't being filled at all. Something tells me its down to character sets, but I'm not sure.
Any help much appreciated.
EDIT: I tried parsing the JSON raw, and that worked fine.
EDIT: The data is being retrieved fine. Just NSLog'ed the data variable.
