我试图将 subview 屏蔽到 super View ,但 ImageView 没有屏蔽到 super View
应该如何
代码
class TicketView: UIView {
var img = UIImage(named: "social-event.jpg")
var imageView = UIImageView()
override func draw(_ rect: CGRect) {
let path = UIBezierPath(rect: rect)
let width:CGFloat = 11
let height:CGFloat = 11
let roundLeft = UIBezierPath(roundedRect: CGRect(x: -(width/2), y: -(height/2), width: width, height: height), cornerRadius: (height/2))
let roundLeftBotton = UIBezierPath(roundedRect: CGRect(x: -(width/2), y: (rect.height)-(height/2), width: width, height: height), cornerRadius: (height/2))
let roundRight = UIBezierPath(roundedRect: CGRect(x: (rect.width)-(width/2), y: -(height/2), width: width, height: height), cornerRadius: (height/2))
let roundRightBottom = UIBezierPath(roundedRect: CGRect(x: (rect.width)-(width/2), y: (rect.height)-(height/2), width: width, height: height), cornerRadius: (height/2))
let roundRightMiddle = UIBezierPath(roundedRect: CGRect(x: (rect.width*0.7)-(width/2), y: -(height/2), width: width, height: height), cornerRadius: (height/2))
let roundRightMiddleBottom = UIBezierPath(roundedRect: CGRect(x: (rect.width*0.7)-(width/2), y:
(rect.height)-(height/2), width: width, height: height), cornerRadius: (height/2))
path.append(roundLeft.reversing())
path.append(roundLeftBotton.reversing())
path.append(roundRight.reversing())
path.append(roundRightBottom.reversing())
path.append(roundRightMiddle.reversing())
path.append(roundRightMiddleBottom.reversing())
UIColor.green.setFill()
path.fill()
imageView.frame = CGRect(x: 0, y: 0, width: (rect.width * 0.7), height: rect.height)
imageView.backgroundColor = UIColor.black
self.addSubview(imageView)
}
}
到目前为止我尝试过的
1) mask 层
2)剪切图像
最佳答案
制作具有像您的角落一样的图层的新图像,并将其作为蒙版放在您的 View 上。
