Swift Set UIbutton Setbordercolor in Storyboard

Swift set UIButton setBorderColor in Storyboard

Here's my UIButton subclass:

@IBDesignable
public class Button: UIButton {
    @IBInspectable public var borderColor:UIColor? {
        didSet {
            layer.borderColor = borderColor?.cgColor
        }
    }
    @IBInspectable public var borderWidth:CGFloat = 0 {
        didSet {
        layer.borderWidth = borderWidth
        }
    }
    @IBInspectable public var cornerRadius:CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }
}

EDIT:

I created a simple project and added the above IBDesignable subclass. Below are three screen shots of the result. Note that in the Identity inspector I've set the Class to be Button, not UIButton and that it reports that the Designables are "Up to date". Note that in the Attributes inspector these appear as properties at the very top.

Change UIButton BorderColor in Storyboard

For Swift:

Swift 3:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(cgColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.cgColor
        }
    }
}

Swift 2.2:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(CGColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.CGColor
        }
    }
}

Set a border for UIButton in Storyboard

You can use key path.

For example the corner radius (layer.cornerRadius) as describe on the image.
You will not be able to see the effects on storyboard, cause this parameters are evaluated at runtime. Now you can use a swift category in UIView (code bellow the picture) in with @IBInspectable to show the result at the storyboard (If you are using the category, use only cornerRadius and not layer.cornerRadius as a key path.

extension UIView {
    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }
}

Here is category from Peter DeWeese answer that allow use keypath layer.borderUIColor to set the border color.

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

How to create border in UIButton?

You can set the border properties on the CALayer by accessing the layer property of the button.

First, add Quartz

#import <QuartzCore/QuartzCore.h>

Set properties:

myButton.layer.borderWidth = 2.0f;
myButton.layer.borderColor = [UIColor greenColor].CGColor;

See:

https://developer.apple.com/documentation/quartzcore/calayer#//apple_ref/occ/cl/CALayer

The CALayer in the link above allows you to set other properties like corner radius, maskToBounds etc...

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.cornerRadius
layer.borderWidth
layer.borderColor

Update:
layer.masksToBounds = true

Update:
select appropriate Type for Keypath:

How to set the custom border color of UIView programmatically?

If you Use Swift 2.0+

self.yourView.layer.borderWidth = 1
self.yourView.layer.borderColor = UIColor(red:222/255, green:225/255, blue:227/255, alpha: 1).cgColor

How to add only a TOP border on a UIButton?

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, btn.frame.size.width, 1)];
lineView.backgroundColor = [UIColor redColor];
[btn addSubview:lineView];

you can do the same for each border. Adding multiple UIViews you can add bottom and left or top and right or any border you want.

i.e. bottom & left:

UIView *bottomBorder = [[UIView alloc] initWithFrame:CGRectMake(0, btn.frame.size.height - 1.0f, btn.frame.size.width, 1)];
bottomBorder.backgroundColor = [UIColor redColor];

UIView *leftBorder = [[UIView alloc] initWithFrame:CGRectMake(1, 0, 1, btn.frame.size.height)];
leftBorder.backgroundColor = [UIColor redColor];

[btn addSubview:bottomBorder];
[btn addSubview:leftBorder];

if you don't use ARC, remember to release UIViews after adding subviews (or use autorelease).
