UITableView 的圆角 [英] Round upper corners for UITableView

问题描述

我正在尝试为 UITableView 圆角.但表视图没有显示.这里有什么问题?

I'm trying to round upper corners for UITableView. But Table view is not displaying. What is wrong here ?

//TableView 设置

// TableView setup

lazy var tableView: UITableView = {
        let tv = UITableView()
        tv.delegate = self
        tv.dataSource = self
        tv.separatorStyle = .none
        tv.backgroundColor = .white
        tv.layer.masksToBounds = true
        tv.roundUpperCorners(radius: 12)
        return tv
    }()

//圆上角.

 func roundUpperCorners(radius: CGFloat) {
        let maskPath = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: radius, height: radius))
        let maskLayer = CAShapeLayer()
        maskLayer.frame = self.bounds
        maskLayer.path = maskPath.cgPath
        self.layer.mask = maskLayer
    }

推荐答案

它正在工作.感谢 Fahri Azimov 提到在设置桌子的框架后尝试圆角".

It is working. Thanks to Fahri Azimov for mentioning "Try to round the corners after setting the table's frame".

我将这一行 tableView.roundUpperCorners(radius: 12) 移动到 viewDidLayoutSubviews 中.

I moved this line tableView.roundUpperCorners(radius: 12) into viewDidLayoutSubviews.

 override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        tableView.roundUpperCorners(radius: 12)
    }
