Custom UITableViewCell Question

I've created a custom cell class using these instructions: http://www.bdunagan.com/2009/06/28/custom-uitableviewcell-from-a-xib-in-interface-builder/

Now, I have two view controllers: MyPostsViewController and CustomCellViewController. The custom cell is just a cell with a UITableViewCell and has two labels declared and connected. The MyPostsViewController is a UITableView that uses these custom cells. However, I am unsure how to access the two labels of the CustomCellViewController from the MyPostsViewController. I want to access them from the MyPostsViewController because that is where the cellForRowAtIndexPath method is and where I want to set the value of my labels at. How would I do this?

I think the cleanest way to do this is to define IBOutlets on your custom UITableViewCell subclass. Then, when designing your XIB, CTRL+click your custom cell. You should see the outlets there. Drag-drop to hook up your outlets to your labels, just like you normally would with views. Finally, access those IBOutlets in your cellForRowAtIndexPath method.

You should customize (set the values for your labels) in cellForRowAtIndexPath:. To do this, you can set tags for your labels in IB itself (find the tag field in the Attributes inspector). Let's say you set 1 for Label1 & 2 for Label2. Then, your code would look something like (copying from the link you posted)-

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"BDCustomCell"];
    if (cell == nil) {
        // Load the top-level objects from the custom cell XIB.
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"BDCustomCell" owner:self options:nil];
        // Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
        cell = [topLevelObjects objectAtIndex:0];
    }

//customize the cell here
UILabel* label 1 = [cell viewWithTag:1];
label1.text = @"my text";

//similarly label 2

    return cell;
}

HTH,

You don't need a CustomCellViewController if you follow the instructions you posted. Just load your cells from your NIB in your MyPostsViewController.

To access individual subviews of your cell, give them each a distinctive tag, then retrieve them with [cell viewWithTag:42], for example.
