UITableView won't display headerView.xib

Question

Am trying to get a UITableView to display a headerView.xib which I have created, but after building it, nothing shows. Want to make the UITableView editable, and have added three methods to the ItemsViewController.m file, but nothing shows.

What's wrong? Thanks in advance.

Here are the relevant files:

ItemsViewController.h

#import <Foundation/Foundation.h>

@interface ItemsViewController : UITableViewController
{
  IBOutlet UIView *headerView;
}

-(UIView *)headerView;
-(IBAction)addNewItem:(id)sender;
-(IBAction)toggleEditingMode:(id)sender;

@end

ItemsViewController.m

#import "ItemsViewController.h"
#import "BNRItemStore.h"
#import "BNRItem.h"

@implementation ItemsViewController // Incomplete implementation

-(id)init
{
  // Call the superclass's designated initializer
  self = [super initWithStyle:UITableViewStyleGrouped];
  if (self) {
    for(int i = 0; i < 5; i++) {
      [[BNRItemStore sharedStore]createItem];
    }

  }
  return self;
}

-(id)initWithStyle:(UITableViewStyle)style
{
  return [self init];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
  return [[[BNRItemStore sharedStore]allItems]count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{


  // Check for a reusable cell first, use that if it exists
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"];

  // If there is no reusable cell of this type, create a new one
  if (!cell) {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"];
  } 

  // Set the text on the cell with the description of the item
  // that is at the nth index of items, where n = row this cell
  // will appear in on the tableview
  BNRItem *p = [[[BNRItemStore sharedStore]allItems]objectAtIndex:[indexPath row]];

  [[cell textLabel]setText:[p description]];

  return cell;
}

-(UIView *)headerView
{
  // If we haven't loaded the headerView yet
  if (!headerView) {
    //Load HeaderView.xib
    [[NSBundle mainBundle]loadNibNamed:@"HeaderView" owner:self options:nil];
  }
  return headerView;
}

-(UIView *)tableView:(UITableView *)tv viewForHeaderInSection:(NSInteger)sec
{
  return [self headerView];
}

-(CGFloat)tableView:(UITableView *)tv heightForHeaderInSection:(NSInteger)sec
{
  // The height of the header view should be determined from the height of the 
  // view in the XIB file
  return [[self headerView]bounds].size.height;
}



@end

One or both of the following things is not set up correctly. First, the File's Owner object in HeaderView.xib needs to have its class set to ItemsViewController. After that, the headerView outlet needs to be connected from File's Owner to the top-level view in the xib.
