如何在曲线的左上角添加uiview。
我已经做了类似的事情
class curvedView: UIView {
override func draw(_ rect: CGRect) {
let color = UIColor.blue
let y:CGFloat = 0
let myBezier = UIBezierPath()
myBezier.move(to: CGPoint(x: 0, y: y))
myBezier.addQuadCurve(to: CGPoint(x: rect.width, y: y), controlPoint: CGPoint(x: rect.width / 2, y: rect.height * 2))
myBezier.addLine(to: CGPoint(x: rect.width, y: rect.height))
myBezier.addLine(to: CGPoint(x: 0, y: rect.height))
myBezier.close()
color.setFill()
myBezier.fill()
}
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = UIColor.clear
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.backgroundColor = UIColor.clear
}
}
但这会创建U形曲线,但我希望曲线从x位置180到Y位置250。
任何帮助都会非常感激。

您可以尝试这些代码,它将为您提供帮助
let path = UIBezierPath(roundedRect:viewToRound.bounds, byRoundingCorners:[.TopRight, .BottomLeft], cornerRadii: CGSizeMake(20, 20))
let maskLayer = CAShapeLayer()
maskLayer.path = path.CGPath
viewToRound.layer.mask = maskLayer
