Loading more than one custom cell from Nib

This works perfect if I return just 1 row of cells. But if I put more than 1 I get the error message: "index 1 beyond bounds [0 .. 0]"

I have made a xib file that has one table cell with a unique design and I just want to use that over and over only changing some labels. Am I going about this the wrong way?

    - (void)viewDidLoad
    {
        [super viewDidLoad];

        // Uncomment the following line to preserve selection between presentations.
        // self.clearsSelectionOnViewWillAppear = NO;

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem;
    }

    - (void)didReceiveMemoryWarning
    {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }

    #pragma mark - Table view data source

    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
    {

        // Return the number of sections.
        return 1;
    }

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {

        // Return the number of rows in the section.
        return 2;
    }


    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *simpleTableIdentifier = @"Cell";

        SectionCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

        if (cell == nil)
        {


            NSArray * nib = [[NSBundle mainBundle] loadNibNamed:@"ButtonCell" owner:self options:nil];

cell = [[SectionCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];

            cell = (SectionCell *)[nib objectAtIndex:0];

        }


        cell.backgroundView.layer.masksToBounds = YES;
        cell.backgroundView.layer.cornerRadius = 20.0;

        cell.name.text=@"Cell Test";


        tableView.backgroundView = nil;
        tableView.backgroundColor = [UIColor clearColor];
        return cell;
    }

    /*
    // Override to support conditional editing of the table view.
    - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
    {
        // Return NO if you do not want the specified item to be editable.
        return YES;
    }
    */


    - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        return 78;
    }

Found the answer. I had to not use static for the table view and use dynamic prototype. The only downside is I couldn't use the custom xib cell and had to modify the default cell to look as close as possible to my static cell.

Change to this code snipped:

if (cell == nil)
    cell = [[[SectionCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier] autorelease];

and remove your NSBundle logic as it is no longer necessary since you are instantiating the cell object yourself.

Example:

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *simpleTableIdentifier = @"Cell";
        SectionCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
        if (cell == nil)
            cell = [[[SectionCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier ] autorelease];

        cell.backgroundView.layer.masksToBounds = YES;
        cell.backgroundView.layer.cornerRadius = 20.0;
        cell.name.text=@"Cell Test";
        tableView.backgroundView = nil;
        tableView.backgroundColor = [UIColor clearColor];
        return cell;
    }

Tip:

It isn't necessary to continuously set your tableview backgrounds the way you do. You can set it when your object is first loaded.

Instead of using :

cell = [nib objectAtIndex:indexPath.row];

use:

if (cell == nil) {
    NSArray * nib = [[NSBundle mainBundle] loadNibNamed:@"ButtonCell" owner:self options:nil];
    cell = (SectionCell *)[nib objectAtIndex:0];

}

Because your nib probably has only one object i.e your custom table view cell.

PS: Assuming you have a xib named "ButtonCell" having a single custom view with its custom class set to "SectionCell"
