Question

I used willDisplayCell delegate method to show a custom background image to a UITableViewCell.

- (void)tableView:(UITableView *)tableView 
           willDisplayCell:(UITableViewCell *)cell 
           forRowAtIndexPath:(NSIndexPath *)indexPath {

    static UIImage* bgImage = nil;
    if (bgImage == nil) {
        bgImage = [UIImage imageNamed:@"myImage.png"];
    }
    cell.backgroundView = [[UIImageView alloc] initWithImage:bgImage];
}

When I run the app in the simulator, the background only for the cells that are drawn are changed, is there a way to change all cells’ background?

I have worked this code.It’s working good .you can try this code.

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"Cell"] autorelease];



        UIImageView *cellBackView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 100)];
        cellBackView.backgroundColor=[UIColor clearColor];


            cellBackView.image = [UIImage imageNamed:@"list.png"];



        cell.backgroundView = cellBackView;
        cell.selectionStyle=UITableViewCellSelectionStyleNone;




    return cell;



}
