我的picker view預設被選擇的那個row會是灰色的

我想把它變成白色（無特殊樣式）
試著修改了viewForRow:forComponent也沒有用
let specificView = UIView.init()
specificView.frame = CGRect.init(x: 0, y: 0, width: 130, height: 45)
specificView.backgroundColor = UIColor.white
let specificLable = UILabel.init(frame: CGRect.init(x: 0, y: 0,
width: 130, height: 45))
specificLable.textAlignment = .center
specificLable.text = "aaaa"
specificLable.textColor = UIColor.black
specificView.addSubview(specificLable)
return specificView
請問要怎樣才能把那灰色的背景顏色拿掉?
