title: iOS dequeueReusableCellWithIdentifier is always returning null
body: <p>I'm really frustrated at this point. Dequeueing a reusable cell with identifier is always returning null.</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
      static NSString *CellIdentifier = @"Cell";
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      if(cell == nil) {
          NSLog(@"INIT");
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
      }
      return cell;
  }
  </code></pre>
  
  <p>What am i doing wrong here? Thanks.</p>
