Reloading tableview after fetching asynchronous JSON data - iphone

Question

I have used asynchronous JSON request and response to get some data. I want to populate it in a tableview. However, all I see is blank table cells. I tried doing a reloadData but it is not working. Here is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
responseData = [[NSMutableData data] retain];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://strong-earth-32.heroku.com/stores.aspx"]];//asynchronous call
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[responseData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
NSLog(#"%#", error);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
[responseData release];
SBJsonParser *parser = [[SBJsonParser alloc]init];
resultData = [[parser objectWithString:responseString error:nil]copy];
NSArray *storeArray = [[NSArray alloc]init];
storeArray= [resultData objectForKey:#"stores"];
populatedStoreArray = [[NSMutableArray alloc]init];
images = [[NSMutableArray alloc] init];
...........
[populatedStoreArray addObject:tempStore];
}
[self.storeDetailsTable reloadData];
[parser release];
}
The tableview looks like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
StoreCell *cell = (StoreCell *) [tableView dequeueReusableCellWithIdentifier:#"StoreCell"];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"StoreCellView" owner:nil options:nil];
for (id currentObject in topLevelObjects) {
if ([currentObject isKindOfClass:[UITableViewCell class]]) {
cell = (StoreCell *) currentObject;
break;
}
}
}
Store *storeAtIndex = [populatedStoreArray objectAtIndex:[indexPath row]];
cell.storePhoneNumber.text = [storeAtIndex phone];
cell.storeAddress.text = [storeAtIndex address];
cell.storeImage.image = [images objectAtIndex:[indexPath row]];
return cell;
}
Some more of my code:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [populatedStoreArray count];
}
The header file:
#interface FirstViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
IBOutlet UITableView *storeDetailsTable;
}
#property (nonatomic, retain) IBOutlet UITableView *storeDetailsTable;
#property (nonatomic, strong) NSDictionary *resultData;
#property (nonatomic, strong) NSMutableArray *populatedStoreArray;
#property (nonatomic, strong) NSMutableArray *images;
#property (nonatomic, strong) NSMutableData *responseData;
#end
Any pointers will be appreciated because everywhere I search, I'm told to use reloadData which is not working. In fact, xcode is not even prompting me when I use it.
Thank you.

Maybe you missed this line:
storeDetailsTable.delegate=self;
