I have a grouped UITableView with a custom UITableViewCell class and I am adding a custom background image to each cell. However, when I do this, the cell's separator is not visible. If simply switch the table style to Plain instead of Grouped, the separator is showing up.

I need the grouped table - how do I make the separator show up?

Here's my code:

@interface MyCustomTableViewCell : UITableViewCell

@end

@implementation MyCustomTableViewCell

// because I'm loading the cell from a xib file
- (id)initWithCoder:(NSCoder *)coder
{
    self = [super initWithCoder:coder];
    if (self)
    {
        // Create a background image view.  
        self.backgroundView = [[UIImageView alloc] init];
    }
    return self;
}


// MyViewController

- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //
    // standard cell dequeue + create cell code here
    //

    //
    // Configure the cell background now
    //
    UIImage *backgroundImage = [UIImage imageNamed:@"odd_row.png"];
    if (indexPath.row % 2 == 0)
    {
        backgroundImage = [UIImage imageNamed:@"even_row.png"];    
    }

    UIImageView *backgroundView = (UIImageView *)cell.backgroundView;
    backgroundView.image = backgroundImage; 
}
