Is it possible to set UIView border properties from interface builder?

Actually you can set some properties of a view's layer through interface builder. I know that I can set a layer's borderWidth and cornerRadius through xcode. borderColor doesn't work, probably because the layer wants a CGColor instead of a UIColor.

You might have to use Strings instead of numbers, but it works!

layer.cornerRadiuslayer.borderWidthlayer.borderColor

Update: layer.masksToBounds = true

Update: select appropriate Type for Keypath:

Rich86Man's answer is correct, but you can use categories to proxy properties such as layer.borderColor. (From the ConventionalC CocoaPod)

CALayer+XibConfiguration.h:

#import <QuartzCore/QuartzCore.h>#import <UIKit/UIKit.h>@interface CALayer(XibConfiguration)// This assigns a CGColor to borderColor.@property(nonatomic, assign) UIColor* borderUIColor;@end

CALayer+XibConfiguration.m:

#import "CALayer+XibConfiguration.h"@implementation CALayer(XibConfiguration)-(void)setBorderUIColor:(UIColor*)color{    self.borderColor = color.CGColor;}-(UIColor*)borderUIColor{    return [UIColor colorWithCGColor:self.borderColor];}@end

layer.borderUIColor

The result will be apparent during runtime, not in Xcode.

Edit: You also need to set layer.borderWidth to at least 1 to see the border with the chosen color.

In Swift 2.0:

extension CALayer {    var borderUIColor: UIColor {        set {            self.borderColor = newValue.CGColor        }        get {            return UIColor(CGColor: self.borderColor!)        }    }}

In Swift 3.0:

extension CALayer {    var borderUIColor: UIColor {        set {            self.borderColor = newValue.cgColor        }        get {            return UIColor(cgColor: self.borderColor!)        }    }}

Similar answer to iHulk's one, but in Swift

Add a file named UIView.swift in your project (or just paste this in any file) :

import UIKit@IBDesignable extension UIView {    @IBInspectable var borderColor: UIColor? {        set {            layer.borderColor = newValue?.cgColor        }        get {            guard let color = layer.borderColor else {                return nil            }            return UIColor(cgColor: color)        }    }    @IBInspectable var borderWidth: CGFloat {        set {            layer.borderWidth = newValue        }        get {            return layer.borderWidth        }    }    @IBInspectable var cornerRadius: CGFloat {        set {            layer.cornerRadius = newValue            clipsToBounds = newValue > 0        }        get {            return layer.cornerRadius        }    }}

Then this will be available in Interface Builder for every button, imageView, label, etc. in the Utilities Panel > Attributes Inspector :

Note: the border will only appear at runtime.
