UITableViewCellAccessoryDisclosureIndicator doesn't render the arrow

That’s really a minor annoyance, but even if I add the mentioned accessoryType to my cell (Episode 2, at the end), I don’t see any arrow appearing in the corresponding cell.
My code is

#import "recipeViewController.h" 
#import "recipeAppDelegate.h" 

@implementation recipeViewController

- (NSInteger) tableView:(UITableView *)tv numberOfRowsInSection:(NSInteger) section {
    return 3;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"recipeCell"];
    if(nil == cell) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"recipeCell"] autorelease];
    }
    if(indexPath.row == 0) {
        cell.text = @"Cherry Pie";
    } else if(indexPath.row == 1) {
        cell.text = @"Cake";
    } else if(indexPath.row == 2) {
        cell.text = @"Cookie";
    }
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    return cell;
}

What am I missing?

thanks!

Of course the solution was very trivial… the UITableView was in fact a bit larger of the View, so that arrows were outside the visible area.
