iPhone Background Image for Table Cell

How can I make the background of the accessory clear? I've managed to set the rest of the elements to [UIColor clearcolor] but it doesn't work for the accessory...

Here's what my progress looks like:

    [self.accessoryView setOpaque: NO];

    self.accessoryView.backgroundColor = [UIColor clearColor];

    self.backgroundColor = [UIColor clea开发者_运维问答rColor];

    self.contentView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Icon.png"]];

    self.accessoryView.backgroundColor = [UIColor clearColor];

Thanks for any help you guys can offer!

have you tried

cell.accessoryView.backgroundColor = [UIColor clearColor];
