问题描述
我想让底部圆形查看在此处输入图片描述
推荐答案
我认为这非常接近您想要的:
I think this is really close to what you want:
rectView 是您的初始视图;您可以使用quad曲线高度的+50来调整曲线
The rectView is your initial view;You can play with the + 50 of quad curve height to adjust the curve
let rectView = UIView(frame: CGRect(x: 50, y: 100, width: 200, height: 200))
rectView.backgroundColor = .red
view.addSubview(rectView)
let arcBezierPath = UIBezierPath()
arcBezierPath.move(to: CGPoint(x: 0, y: rectView.frame.height))
arcBezierPath.addQuadCurve(to: CGPoint(x: rectView.frame.width, y: rectView.frame.height), controlPoint: CGPoint(x: rectView.frame.width / 2 , y: rectView.frame.height + 50 ))
arcBezierPath.close()
let shapeLayer = CAShapeLayer()
shapeLayer.path = arcBezierPath.cgPath
shapeLayer.fillColor = UIColor.red.cgColor
rectView.layer.insertSublayer(shapeLayer, at: 0)
rectView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
rectView.layer.cornerRadius = 10
rectView.layer.shadowRadius = 3
rectView.layer.shadowColor = UIColor.black.cgColor
rectView.layer.shadowOffset = CGSize(width: 0, height: 0)
rectView.layer.shadowOpacity = 0.25
也许,更好:您可以创建您的视图:
Maybe, even better: You can create your view:
let rectView = UIView(frame: CGRect(x: 50, y: 100, width: 200, height: 200))
view.addSubview(rectView)
扩展 UIView
extension UIView {
func addBottomArc(ofHeight height: CGFloat, topCornerRadius: CGFloat) {
let arcBezierPath = UIBezierPath()
arcBezierPath.move(to: CGPoint(x: 0, y: frame.height))
arcBezierPath.addQuadCurve(to: CGPoint(x: frame.width, y: frame.height), controlPoint: CGPoint(x: frame.width / 2 , y: frame.height + height ))
arcBezierPath.close()
let shapeLayer = CAShapeLayer()
shapeLayer.path = arcBezierPath.cgPath
shapeLayer.fillColor = UIColor.red.cgColor
layer.insertSublayer(shapeLayer, at: 0)
layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
layer.cornerRadius = topCornerRadius
}
}
所以你可以像这样设置高度和圆角半径:
So you can set the height and the corner radius like this:
rectView.addBottomArc(ofHeight: 50, topCornerRadius: 15)
然后将您需要的阴影添加到您的视图中:
and than add the shadow you need to your view:
rectView.layer.shadowRadius = 3
rectView.layer.shadowColor = UIColor.black.cgColor
rectView.layer.shadowOffset = CGSize(width: 0, height: 0)
rectView.layer.shadowOpacity = 0.25
