Swift3 round two corners of UIView - ios

Question

I know this question already asked so many times and their solutions also available but nothing works for me.
I am using Swift3 and I want to round any two sides of UIView for this purpose I found the following solution
Create a rectangle with just two rounded corners in swift?
and following is my code snippet of the above solution
extension UIView {
/**
Rounds the given set of corners to the specified radius
- parameter corners: Corners to round
- parameter radius: Radius to round to
*/
func round(corners: UIRectCorner, radius: CGFloat) -> Void {
layer.addSublayer(_round(corners: corners, radius: radius))
}
/**
Rounds the given set of corners to the specified radius with a border
- parameter corners: Corners to round
- parameter radius: Radius to round to
- parameter borderColor: The border color
- parameter borderWidth: The border width
*/
func round(corners: UIRectCorner, radius: CGFloat, borderColor: UIColor, borderWidth: CGFloat) {
let mask = _round(corners: corners, radius: radius)
addBorder(mask: mask, borderColor: borderColor, borderWidth: borderWidth)
}
/**
Fully rounds an autolayout view (e.g. one with no known frame) with the given diameter and border
- parameter diameter: The view's diameter
- parameter borderColor: The border color
- parameter borderWidth: The border width
*/
func fullyRound(diameter: CGFloat, borderColor: UIColor, borderWidth: CGFloat) {
layer.masksToBounds = true
layer.cornerRadius = diameter / 2
layer.borderWidth = borderWidth
layer.borderColor = borderColor.cgColor;
}
}
private extension UIView {
func _round(corners: UIRectCorner, radius: CGFloat) -> CAShapeLayer {
let path = UIBezierPath(roundedRect: bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
let mask = CAShapeLayer()
mask.path = path.cgPath
self.layer.mask = mask
return mask
}
func addBorder(mask: CAShapeLayer, borderColor: UIColor, borderWidth: CGFloat) {
let borderLayer = CAShapeLayer()
borderLayer.path = mask.path
borderLayer.fillColor = UIColor.clear.cgColor
borderLayer.strokeColor = borderColor.cgColor
borderLayer.lineWidth = borderWidth
borderLayer.frame = bounds
layer.addSublayer(borderLayer)
}
}
This is the result I got. I don't know what I am doing wrong.
Can anyone please solve this?

Answer 1

Code tested and worked in Swift 3.
Use below extension to create roundCorners.
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
}
}
Usage: in viewDidLoad
yourViewName.roundCorners(corners: [.topRight, .bottomLeft], radius: 10)
Output:

First of all you will need to Make IBOutlet for that Textfield or Button which you
need to Be Rounded Corner
Go to The ViewDidLoad() Method
Write the name of IBOutLet
Example Code mybutton.layer.cornerRadius=10
Here is the Solution to Your Problem
