Answer 1

你可以尝试下面给出的每个按钮：

let tabBar1Path = UIBezierPath()

let tabBar1Layer = CAShapeLayer()

tabBar1Path.move(to: CGPoint(x: 0, y: 0))

tabBar1Path.addLine(to: CGPoint(x: self.view!.frame.size.width * 0.25, y: 0))

tabBar1Path.addLine(to: CGPoint(x: self.view!.frame.size.width * 0.2, y: tabBarHeight))

tabBar1Path.addLine(to: CGPoint(x: 0, y: tabBarHeight))

tabBar1Path.addLine(to: CGPoint(x: 0, y: 0))

tabBar1Layer.path = trianglePath.cgPath

tabBar1Layer.fillColor = UIColor.black.cgColor

tabBarButton1.layer.addSublayer(triangleLayer)
