I have looked around to find a solution for setting the background color of the accessoryView to the same background color as the cell´s contentView.
cell.co
For all lines with the same color
cell.backgroundColor = [UIColor colorWithRed:6.0/255.0 green:122.0/255.0 blue:145.0/255.0 alpha:1.0f];
For 2 colors
cell.backgroundColor = [UIColor colorWithRed:6.0/255.0 green:122.0/255.0 blue:145.0/255.0 alpha:1.0f];
if ((cell.backgroundColor = (indexPath.row % 2 == 0 ? [UIColor colorWithRed:6.0/255.0 green:122.0/255.0 blue:145.0/255.0 alpha:1.0f] : [UIColor colorWithRed:2.0/255.0 green:68.0/255.0 blue:80.0/255.0 alpha:1.0f]))){
cell.textLabel.textColor = [UIColor whiteColor];
}
