直接使用代理方法attributedTitleForRow即可实现，不需要使用 func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView 方法

        case 1: // 月
            let str = "\(1 + row)月"
            return self.attributedStr(from: str)
        case 2: // 日
            let str = "\(1 + row)日"
            return self.attributedStr(from: str)
        case 3: // 时
            let str = "\(row)时"
            return self.attributedStr(from: str)
        case 4: // 分
            let str = "\(row)分"
            return self.attributedStr(from
