How to set the custom border color of UIView programmatically?

Question

I am trying to set the custom border color of UIView programmatically in Swift.

Answer 1

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:

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

swift 3

func borderColor(){

    self.viewMenuItems.layer.cornerRadius = 13
    self.viewMenuItems.layer.borderWidth = 1
    self.viewMenuItems.layer.borderColor = UIColor.white.cgColor
}

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)
