The answer is
We can create method for it. Simply use it.
public func createBorderForView(color: UIColor, radius: CGFloat, width: CGFloat = 0.7) {
self.layer.borderWidth = width
self.layer.cornerRadius = radius
self.layer.shouldRasterize = false
self.layer.rasterizationScale = 2
self.clipsToBounds = true
self.layer.masksToBounds = true
let cgColor: CGColor = color.cgColor
self.layer.borderColor = cgColor
}
Swift 5*
I, always use view extension to make view corners round, set border color and width and it has been the most convenient way for me. just copy and paste this code and controlle these properties in attribute inspector.
extension UIView {
@IBInspectable
var cornerRadius: CGFloat {
get {
return layer.cornerRadius
}
set {
layer.cornerRadius = newValue
}
}
@IBInspectable
var borderWidth: CGFloat {
get {
return layer.borderWidth
}
set {
layer.borderWidth = newValue
}
}
@IBInspectable
var borderColor: UIColor? {
get {
if let color = layer.borderColor {
return UIColor(cgColor: color)
}
return nil
}
set {
if let color = newValue {
layer.borderColor = color.cgColor
} else {
layer.borderColor = nil
}
}
}
}
Use @IBDesignable and @IBInspectable to do the same.
They are re-useable, easily modifiable from the Interface Builder and the changes are reflected immediately in the Storyboard
Conform the objects in the storyboard to the particular class
Code Snippet:
@IBDesignable
class CustomView: UIView{
@IBInspectable var borderWidth: CGFloat = 0.0{
didSet{
self.layer.borderWidth = borderWidth
}
}
@IBInspectable var borderColor: UIColor = UIColor.clear {
didSet {
self.layer.borderColor = borderColor.cgColor
}
}
override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
}
}
Allows easy modification from Interface Builder:
In Swift 4 you can set the border color and width to UIControls using below code.
let yourColor : UIColor = UIColor( red: 0.7, green: 0.3, blue:0.1, alpha: 1.0 )
yourControl.layer.masksToBounds = true
yourControl.layer.borderColor = yourColor.CGColor
yourControl.layer.borderWidth = 1.0
< Swift 4, You can set UIView's border width and border color using the below code.
yourView.layer.borderWidth = 1
yourView.layer.borderColor = UIColor.red.cgColor
Swift 5.2, UIView+Extension
extension UIView {
public func addViewBorder(borderColor:CGColor,borderWith:CGFloat,borderCornerRadius:CGFloat){
self.layer.borderWidth = borderWith
self.layer.borderColor = borderColor
self.layer.cornerRadius = borderCornerRadius
}
}
You used this extension;
yourView.addViewBorder(borderColor: #colorLiteral(red: 0.6, green: 0.6, blue: 0.6, alpha: 1), borderWith: 1.0, borderCornerRadius: 20)
swift 3
func borderColor(){
self.viewMenuItems.layer.cornerRadius = 13
self.viewMenuItems.layer.borderWidth = 1
self.viewMenuItems.layer.borderColor = UIColor.white.cgColor
}
Write the code in your viewDidLoad()
self.view.layer.borderColor = anyColor().CGColor
And you can set Color with RGB
func anyColor() -> UIColor {
return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 1.0)
}
Learn something about CALayer in UIKit
You can write an extension to use it with all the UIViews eg. UIButton, UILabel, UIImageView etc. You can customise my following method as per your requirement, but I think it will work well for you.
extension UIView{
func setBorder(radius:CGFloat, color:UIColor = UIColor.clearColor()) -> UIView{
var roundView:UIView = self
roundView.layer.cornerRadius = CGFloat(radius)
roundView.layer.borderWidth = 1
roundView.layer.borderColor = color.CGColor
roundView.clipsToBounds = true
return roundView
}
}
Usage:
btnLogin.setBorder(7, color: UIColor.lightGrayColor())
imgViewUserPick.setBorder(10)
Swift 3.0
groundTrump.layer.borderColor = UIColor.red.cgColor
swift 3.0
self.uiTextView.layer.borderWidth = 0.5
self.txtItemShortDes.layer.borderColor = UIColor(red:205.0/255.0, green:205.0/255.0, blue:205.0/255.0, alpha: 1.0).cgColor
