no title nor author name appearing in the simulated tableview app. When is tableview:cellForRowAtIndexPath called ?

The tableView:cellForRowAtIndexPath method is essentially presenting a cell to the table view controller (hence why we return 'cell' in the method). So when you define what your cell looks like and contains, this method then returns 'cell' so that it shows up in your table view. So when you run the app, if you are seeing cells, then your tableView:cellForRowAtIndexPath is being called. If there are no cells, then this is most likely where the issue is. Here is the example method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    BlogPost *blogPost = [self.blogPosts objectAtIndex:indexPath.row];

    if ( [blogPost.thumbnail isKindOfClass:[NSString class]]) {
        NSData *imageData = [NSData dataWithContentsOfURL:blogPost.thumbnailURL];
        UIImage *image = [UIImage imageWithData:imageData];

        cell.imageView.image = image;
    } else {
        cell.imageView.image = [UIImage imageNamed:@"treehouse.png"];
    }
    cell.textLabel.text = blogPost.title;
    cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ - %@",blogPost.author,[blogPost formattedDate]];
    return cell;
}

Yea alright, got that, but what happens to the NSLog I inserted in that function that does not appear in the console ?

My code below:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    BR2BlogPost *blogPost = [self.blogPosts objectAtIndex:indexPath.row];

    NSLog(@"ok");

    cell.textLabel.text = blogPost.title;
    cell.detailTextLabel.text = blogPost.author;

    return cell;
}```

a screenshot of the consol and the simulator :

looks like I couldn't embed the picture...but here is what the consol looks like when I run the blog reader app :

2014-09-01 13:42:25.111 BlogReader2[40975:60b] Cannot find executable for CFBundle 0x8ea5420 </Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/System/Library/AccessibilityBundles/CertUIFramework.axbundle> (not loaded)

Hm, I would check 3 things:

1. Make sure you have the correct frameworks in your Xcode project.
2. Check the syntax in the BR2BlogPost class.
3. Try resetting your simulator. Run the app and go to iOS Simulator > Reset Content and Settings...

Good luck!
