我使用此代码
创建了UIBezierPath
的以下图片
//// Bezier Drawing
let bezierPath = UIBezierPath()
bezierPath.move(to: CGPoint(x: 360, y: 0))
bezierPath.addCurve(to: CGPoint(x: 360, y: 75), controlPoint1: CGPoint(x: 359.53, y: 30.5), controlPoint2: CGPoint(x: 359.91, y: 55.45))
bezierPath.addCurve(to: CGPoint(x: 360, y: 153.78), controlPoint1: CGPoint(x: 360.35, y: 153.21), controlPoint2: CGPoint(x: 360, y: 153.78))
bezierPath.addCurve(to: CGPoint(x: 180, y: 153.78), controlPoint1: CGPoint(x: 360, y: 153.78), controlPoint2: CGPoint(x: 271.2, y: 212.77))
bezierPath.addCurve(to: CGPoint(x: 0, y: 153.78), controlPoint1: CGPoint(x: 88.8, y: 94.8), controlPoint2: CGPoint(x: 0, y: 153.78))
bezierPath.addLine(to: CGPoint(x: 0, y: 0))
bezierPath.addLine(to: CGPoint(x: 360, y: 0))
UIColor.green.setFill()
bezierPath.fill()
现在我想使用Slider将角半径赋予此跟随图像的TopLeft
和TopRight
。
我试过以下代码,但它对我不起作用。
var cornerPath = path
cornerPath = UIBezierPath(roundedRect:self.imgTop.bounds,
byRoundingCorners:[.topLeft, .topRight],
cornerRadii: CGSize(width: CGFloat(cornerRadius),
height: CGFloat(cornerRadius)))
path.lineWidth = 1.0
let maskLayer = CAShapeLayer()
maskLayer.path = cornerPath.cgPath
self.imgTop.layer.mask = maskLayer
let maskLayerTop = CAShapeLayer()
maskLayerTop.fillColor = UIColor.white.cgColor
maskLayerTop.backgroundColor = UIColor.clear.cgColor
maskLayerTop.path = pathTop?.cgPath
maskLayerTop.cornerRadius = CGFloat(cornerRadius)
//maskLayerTop.masksToBounds = true
maskLayerTop.shadowRadius = CGFloat(cornerRadius)
maskLayerTop.fillColor = UIColor.green.cgColor
maskLayerTop.shadowColor = UIColor.blue.cgColor
imgTop.layer.mask = maskLayerTop
我还尝试将角半径应用于图像视图,但它不起作用。我希望角半径如下图所示。
请帮忙!
注意:我已创建一条路径来创建以下图片
答案 0 :(得分:3)
var = cornerRadiudSize = CGSize(width: 50.0, height: 50.0) //this is your global variable that you can change based on the slider and then draw
let p = UIBezierPath(roundedRect: rect, byRoundingCorners: .allCorners, cornerRadii: cornerRadiudSize)
p.addClip()
PS:代替所有角落设置你想要的角落
