如何设置状态栏为白色

在info中添加key：View controller-based status bar appearance value: NO
然后在General -> Deployment Info -> Status Bar Style 设置为：Light

给 UIButton 添加下划线(其他同理）

navView.addSubview(disconnectButton)
        let disStr = NSMutableAttributedString(string: NSLocalizedString("LSEBike_Disconnect", comment: "断开"))
        disStr.addAttribute(NSUnderlineStyleAttributeName, value: 1, range: NSMakeRange(0, disStr.length))
        disStr.addAttribute(NSForegroundColorAttributeName, value: UIColor.white, range: NSMakeRange(0, disStr.length))
        disconnectButton.setAttributedTitle(disStr, for: .normal)
        disconnectButton.titleLabel?.font = UIFont.systemFont(ofSize: 15)
        disconnectButton.addTarget(self, action: #selector(self.clickDisconnect), for: .touchUpInside)
        disconnectButton.snp.makeConstraints { (make) in
            make.width.equalTo(60)
            make.height.equalTo(44)
            make.left.equalTo(0)
            make.top.equalTo(20)
        }
