绕过UIButton的左边界

要围绕UIButton的左下角,我抓了code from this answer并修改了一行:borderLayer.strokeColor = GenerateShape.UIColorFromHex(0x989898, alpha: (1.0-0.3)).CGColor b / c它不起作用。

但是,UIButton的左边框未四舍五入。如何解决?

enter image description here

代码

    button.frame = CGRect(x: 0, y: 0, width: 0.5*popUpView.frame.width, height: 0.25*popUpView.frame.height)
    button.layer.borderWidth = 3
    button.roundBtnCorners(roundedCorners, radius: cornerRadius)

extension UIButton{
    // Round specified corners of button
    func roundBtnCorners(_ corners:UIRectCorner, radius: CGFloat)
    {
        let borderLayer = CAShapeLayer()
        borderLayer.frame = self.layer.bounds
        borderLayer.strokeColor = UIColor(red: 168/266, green: 20/255, blue: 20/255, alpha: 0.7).cgColor
        borderLayer.fillColor = UIColor.clear.cgColor
        borderLayer.lineWidth = 1.0
        let path = UIBezierPath(roundedRect: self.bounds,
                                byRoundingCorners: corners,
                                cornerRadii: CGSize(width: radius, height: radius))
        borderLayer.path = path.cgPath
        self.layer.addSublayer(borderLayer);
    }
}

坚持:

self.layer.addSublayer(borderLayer)

尝试:

self.layer.mask = borderLayer

我看不出你是如何为roundBtnCorners创建参数的,但是下面是我在代码中更改的行并且它有效。我会检查以确保您传递的是正确的参数。

    button.roundBtnCorners(.bottomLeft , radius: 10)

解决了!这是因为我的button.layer.borderWidth = 3正在绘制一个非常厚的矩形,所以我看不到roundBtnCorners

绘制的边框

我删除了以下一行:

button.layer.borderWidth = 3

结果:
