Objective C Cell Accessory view

Question

When I try to set the accessory view of a table view cell to a custom type image and run it in the simulator, I see that multiple cells have the accessory view image instead of the one that is currently selected. But when I set the accessory view to "cell.accessoryType = UITableViewCellAccessoryCheckmark;", I don't have this problem. Here is the code.

id item = [_items objectAtIndex:row];

if ([_currentVale isKindOfClass:[NSString class]])
{
    if ([item isEqualToString:_currentVale])
    {

        UIImageView *checkmark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checkmark-outline.png"]];
        checkmark.frame = CGRectMake(0, 0, 20, 20);
        cell.accessoryView = checkmark;
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
}
else if ([_currentVale isKindOfClass:[NSNumber class]])
{
    if ([item isEqualToNumber:_currentVale])
    {
        cell.accessoryType = UITableViewCellAccessoryNone;

    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;


    }
}

Two images of what I'm talking about. Only one value should be chosen in the picker but there is two showing the checkmark

The cells are being reused. You need to set the accessory view also to nil inside the else.

else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
        cell.accessoryView = nil;
    }
