Reload UITableView data not working properly - ios

Question

I have an array objects received from my webservice that I use to populate a UITableView. I'm trying to implement a method that gets a new array from the webservice and redefines my array that populates the table and then reload the tableView to use the new objects from this array.
This is the method that should do the work:
WSCaller *caller = [[WSCaller alloc]init];
arrayFromWS = [caller getArray];
[self.table reloadData];
and it doesn't work. Any ideas?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = #"productsCellIdentifier";
ProductsCell *cell = nil;
cell = (ProductsCell *)[self.table dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
NSArray *topLevelObjects = [[NSBundle mainBundle]loadNibNamed:#"ProductsCell" owner:nil options:nil];
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[ProductsCell class]])
{
cell = (ProductsCell *)currentObject;
break;
}
}
}
if (productsMutableArray)
{
cell.backgroundColor = [UIColor whiteColor];
cell.productName.text = [[self.productsMutableArray objectAtIndex:indexPath.row]objectForKey:#"name"];
}
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [productsMutableArray count];
}

Answer 1

Your datasource implementation is wrong (or at least the snippets are).
First, you aren't retaining the arrayFromWS:
WSCaller *caller = [[WSCaller alloc] init];
arrayFromWS = [caller getArray];
[self.table reloadData];
Second, on your tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: methods, you're using a different array (productsMutableArray).
To fix that, I'd recommend to change the code above for something like (assuming that your productsMutableArray is a strong/retain property:
WSCaller *caller = [[WSCaller alloc] init];
self.productsMutableArray = [NSMutableArray arrayWithArray:[caller getArray]];
[self.table reloadData];
