Comment définir le rayon de l'angle uniquement en mode d'affichage en bas à gauche, à droite et à gauche?
let rectShape = CAShapeLayer()
rectShape.backgroundColor = UIColor.redColor().CGColor
rectShape.bounds = messages.frame
rectShape.position = messages.center
rectShape.path = UIBezierPath(roundedRect: messages.bounds, byRoundingCorners: .BottomLeft | .TopRight, cornerRadii: CGSize(width: 20, height: 20)).CGPath
messages.layer.addSublayer(rectShape)
ce code crée deux rect. Je ne sais pas pourquoi.
Il vous suffit de masquer le calque comme indiqué ci-dessous:
Pour Swift 3 :
let rectShape = CAShapeLayer()
rectShape.bounds = self.myView.frame
rectShape.position = self.myView.center
rectShape.path = UIBezierPath(roundedRect: self.myView.bounds, byRoundingCorners: [.bottomLeft , .bottomRight , .topLeft], cornerRadii: CGSize(width: 20, height: 20)).cgPath
self.myView.layer.backgroundColor = UIColor.green.cgColor
//Here I'm masking the textView's layer with rectShape layer
self.myView.layer.mask = rectShape
Version basse:
let rectShape = CAShapeLayer()
rectShape.bounds = self.myView.frame
rectShape.position = self.myView.center
rectShape.path = UIBezierPath(roundedRect: self.myView.bounds, byRoundingCorners: .BottomLeft | .BottomRight | .TopLeft, cornerRadii: CGSize(width: 20, height: 20)).CGPath
self.myView.layer.backgroundColor = UIColor.greenColor().CGColor
//Here I'm masking the textView's layer with rectShape layer
self.myView.layer.mask = rectShape
(Swift 4/iOS 11) Dites simplement pour le fond:
yourView.clipsToBounds = true
yourView.layer.cornerRadius = 10
yourView.layer.maskedCorners = [.layerMaxXMaxYCorner, .layerMinXMaxYCorner]
pour Up:
yourView.clipsToBounds = true
yourView.layer.cornerRadius = 10
yourView.layer.maskedCorners = [.layerMaxXMinYCorner, .layerMinXMinYCorner]
dans ton cas:
yourView.layer.maskedCorners = [.layerMaxXMaxYCorner, .layerMinXMaxYCorner, .layerMinXMinYCorner]
J'espère que cette aide :)
Testé en xcode 8 et Swift 3
extension UIView {
func roundCorners(_ corners:UIRectCorner, radius: CGFloat) {
let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
let mask = CAShapeLayer()
mask.path = path.cgPath
self.layer.mask = mask
}
}
il utilise comme ça
YourView.roundCorners([.topLeft, .bottomLeft], radius: 10)
Une meilleure réponse pour iOS 11 et iOS 10 en bas serait:
if #available(iOS 11.0, *){
view.clipsToBounds = false
view.layer.cornerRadius = 10
view.layer.maskedCorners = [.layerMaxXMaxYCorner, .layerMinXMaxYCorner]
}else{
let rectShape = CAShapeLayer()
rectShape.bounds = view.frame
rectShape.position = view.center
rectShape.path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: [.bottomLeft , .bottomRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
view.layer.backgroundColor = UIColor.green.cgColor
view.layer.mask = rectShape
}
au cas où cela ne fonctionnerait pas sur iOS 10 et inférieur, essayez d’exécuter le code dans viewDidLayoutSubviews () de votre classe viewcontroller comme ceci
override func viewDidLayoutSubviews() {
if #available(iOS 11.0, *){
}else{
let rectShape = CAShapeLayer()
rectShape.bounds = view.frame
rectShape.position = view.center
rectShape.path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: [.bottomLeft , .bottomRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
view.layer.backgroundColor = UIColor.green.cgColor
view.layer.mask = rectShape
}
override func viewDidLoad() {
let topRight = UIView(frame: CGRect(x: 120, y: 200, width: 120, height: 120))
topRight.roundedTop()
topRight.backgroundColor = .red
self.view.center = topRight.center
self.view.addSubview(topRight)
super.viewDidLoad()
}

extension sur UIView Swift 4: Lien de référence
Voici une extension pour iOS 11+
import Foundation
import UIKit
extension UIView {
func roundCorners(_ corners: CACornerMask, radius: CGFloat, borderColor: UIColor, borderWidth: CGFloat) {
self.layer.maskedCorners = corners
self.layer.cornerRadius = radius
self.layer.borderWidth = borderWidth
self.layer.borderColor = borderColor.cgColor
}
}
Usage:-
self.yourView.roundCorners([.layerMaxXMaxYCorner, .layerMaxXMinYCorner], radius: 20.0, borderColor: UIColor.green, borderWidth: 1)
problème résolu travail en haut à droite et en bas à droite maintenant
Code testé dans les versions iOS 9, 10 et 11
extension UIView {
func roundCorners(_ corners:UIRectCorner,_ cormerMask:CACornerMask, radius: CGFloat) {
if #available(iOS 11.0, *){
self.clipsToBounds = false
self.layer.cornerRadius = radius
self.layer.maskedCorners = cormerMask
}else{
let rectShape = CAShapeLayer()
rectShape.bounds = self.frame
rectShape.position = self.center
rectShape.path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius)).cgPath
self.layer.mask = rectShape
}
}
}
