Question

So I have a view controller which adopts UITableViewDelegate:

@interface MyViewController:UIViewController<UITableViewDelegate>
@property (weak, nonatomic) IBOutlet UITabelView *myTableView;
@end

In the implementation file MyViewController.m, I override

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{}

My question is, how does the height of tabel view row get returned to myTableView and further sets the height of each individual row?

Edited:
Just to be clear, I tried to implement this mechanism in my own custom view class where specific information is asked for to lay out the view. I have no problem using UITabelView itself. 🙂

You question isn’t very clear but the code inside the UITableView which asks the delegate for the cell height would simply be something like this.

CGFloat thisCellHeight = [self.delegate tableView:self heightForRowAtIndexPath:thisCellIndexPath];

It send a message back to the delegate and asks…
