swift 4.1中的侧菜单

1.有两件事我需要帮助一看侧菜单的按钮你会看到它显示在按钮上的表视图控制器

如何删除菜单背景图像中的透明

注意，我是以编程方式完成的，没有故事板

类SideBarView:UIView、UITableViewDelegate、UITableViewDataSource{

var titleArr = [String]()

weak var delegate: SidebarViewDelegate?

override init(frame: CGRect) {
    super.init(frame: frame)

    self.backgroundColor = UIColor(patternImage: UIImage(named: "Rectangle 1473")!)



    //self.backgroundColor=UIColor(red: 54/255, green: 55/255, blue: 56/255, alpha: 1.0)
    self.clipsToBounds=true

    titleArr = ["Maddy Alexander", "Messages", "Contact", "Settings", "History", "Help", "Sign Out"]

    setupViews()


    myTableView.delegate=self
    myTableView.dataSource=self
    myTableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
    myTableView.tableFooterView=UIView()
    myTableView.separatorStyle = UITableViewCellSeparatorStyle.none
    myTableView.allowsSelection = true
    myTableView.bounces=false
    myTableView.showsVerticalScrollIndicator=false
    myTableView.backgroundColor = UIColor.clear
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return titleArr.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell=tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    cell.backgroundColor = .clear
    cell.selectionStyle = .none
    if indexPath.row == 0 {
        //cell.backgroundColor=UIColor(red: 77/255, green: 77/255, blue: 77/255, alpha: 1.0)
        let cellImg: UIImageView!
        cellImg = UIImageView(frame: CGRect(x: 15, y: 10, width: 80, height: 80))
        cellImg.layer.cornerRadius = 40
        cellImg.layer.masksToBounds=true
        cellImg.contentMode = .scaleAspectFill
        cellImg.layer.masksToBounds=true
        cellImg.image=#imageLiteral(resourceName: "user2")
        cell.addSubview(cellImg)

        let cellLbl = UILabel(frame: CGRect(x: 110, y: cell.frame.height/2-15, width: 250, height: 30))
        cell.addSubview(cellLbl)
        cellLbl.text = titleArr[indexPath.row]
        cellLbl.font=UIFont.systemFont(ofSize: 17)
        cellLbl.textColor=UIColor.white
    } else {
        cell.textLabel?.text=titleArr[indexPath.row]
        cell.textLabel?.textColor=UIColor.white
    }
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    self.delegate?.sidebarDidSelectRow(row: Row(row: indexPath.row))
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    if indexPath.row == 0 {
        return 100
    } else {
        return 60
    }
}

func setupViews() {
    self.addSubview(myTableView)
    myTableView.topAnchor.constraint(equalTo: topAnchor).isActive=true
    myTableView.leftAnchor.constraint(equalTo: leftAnchor).isActive=true
    myTableView.rightAnchor.constraint(equalTo: rightAnchor).isActive=true
    myTableView.bottomAnchor.constraint(equalTo: bottomAnchor).isActive=true
}

let myTableView: UITableView = {
    let table=UITableView()
    table.translatesAutoresizingMaskIntoConstraints=false
    return table
}()

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

}

我建议你试试，它能帮你处理很多事情，所以你不必担心。

至于透明度，你可以使用view.alpha=0.5之类的工具。好的，谢谢你的帮助，我回来后会试试的
