19,299 PointsWhen creating a new instance of blogpost inside the didselectrowatindex path method. How does blogpost have blogposts?
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { BlogPost *blogPost = [self.blogPosts objectAtIndex:indexPath.row]; NSLog(@"%@",blogPost.title);
} How come blogPost isn't just an empty object if it is a new instance of a BlogPost class created locally inside the function call?

16,642 PointsAfter the view loads, our code creates an array, blogPosts array. Using a 'for in' loop, we create a new instance of a BlogPost for every post in the JSON data and add it to the array. Now the TableViewController has a property, blogPosts, that is an array of BlogPost instances. Thereafter (outside of that function) we instantiate a new instance of the BlogPost class and assign it to one of the instances in the blogPosts array.
