Answer 1

Either in your tableView:cellForRowAtIndexPath: set the imageView‘s image to nil before conditionally checking to set the new image or implement prepareForReuse on your cell subclass and set all of the cell’s views values to nil.

This will ensure that reused cells are ‘clean’ before they’re brought on screen.

Alternatively you could edit your switch to look like:

switch (indexPath.row) {
    case 0:
        cell.imageView.image = [UIImage imageNamed:@"new.png"];
        break;

    case 1:
        cell.imageView.image = [UIImage imageNamed:@"new.png"];
        break;
    default:
        cell.imageView.image = nil;
        break;
}
