#pragma mark - Table view data source

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    
    // Configure the cell...
    Event *event = self.eventData [indexPath.row];
    
    cell.textLabel.text = event.title;
    cell.detailTextLabel.text = event.detail;
    
    return cell;
}

Another concern I have is once the tableview is working with AFNetworking 2.0, would I be having issues adding push notifications? (I'm thinking Parse PNs). Since I need to add their API to my project. Last year I gave up on AFNet because I had a problem with both using json callbacks.

I have created a fork with my changes.
They include both some stylistic changes and hopefully a fix in your parsing.

You should try thinking a little about your data structure, i.e. how you want to store events in memory.
Because your problem was caused by a mismatch in how your server structures events and how your client code parses it.

Let's compare the nesting in events2.json with your code.
events2.json: dictionary => array => dictionary
Your code: dictionary
