DesignableButton

November 11, 2023

Features

One centralised class to define you main button styles so they can be reused
Different styles for different button states: Normal/Selected/Disabled
The centralised styles can be set in IB (no more IBOutlets needed for programatical styling)
View the style in IB in realtime. Even changing button to selected state will update IB
Individual buttons can override their centralised styles in IB
Rounded corners and borders are easy with DesignableButton
Buttons with an image above text are easy with DesignableButton

How to install

Add this to your CocoaPods Podfile. Note the IH prefix


                                              
                                                pod ‘IHDesignableButton’

How to use

Create an DesignableButton+Styles.swift extension file in your project


                                              
                                                import UIKit

import IHDesignableButton // if DesignableButton is in CocoaPod

extension DesignableButton {
override open func prepareForInterfaceBuilder() {

super.prepareForInterfaceBuilder()
DesignableButton.setDesignableStyles(isInterfaceBuilder: true)

}
static func setDesignableStyles(isInterfaceBuilder: Bool = false) {
// example style

DesignableButton.setStyle(style: { (designableButton: DesignableButton) -> Void in

if designableButton.isHighlighted || designableButton.isSelected {

// replace this with your style for selected/highlighted states

designableButton.setTitleColor(designableButton.customTextColor ?? UIColor.white, for: UIControlState())

designableButton.backgroundColor = designableButton.selectedColor ?? UIColor.red

designableButton.layer.borderColor = designableButton.selectedColor?.cgColor ?? UIColor.red.cgColor

designableButton.layer.borderWidth = designableButton.borderWidth ?? 0

} else if designableButton.isEnabled {

// replace this with your style for the normal state

designableButton.setTitleColor(designableButton.customTextColor ?? UIColor.white, for: UIControlState())

designableButton.backgroundColor = designableButton.defaultColor ?? UIColor.blue

designableButton.layer.borderColor = designableButton.defaultColor?.cgColor ?? UIColor.blue.cgColor

designableButton.layer.borderWidth = designableButton.borderWidth ?? 0

}

else {

// replace this with your style for the disabled state

designableButton.setTitleColor(designableButton.customTextColor ?? UIColor.lightGray, for: UIControlState())

designableButton.backgroundColor = designableButton.disabledColor ?? UIColor.lightGray()

designableButton.layer.borderColor = designableButton.borderColor?.cgColor ?? UIColor.gray.cgColor

designableButton.layer.borderWidth = designableButton.borderWidth ?? 1

}
// replace this with your style for all states

designableButton.layer.cornerRadius = designableButton.cornerRadius ?? 12
designableButton.setTitle(designableButton.titleLabel?.text, for: .normal)
}, for: “primary”) // this is the name/key of your style

}

}

In the setDesignableStyles() method you can call DesignableButton.setStyle() to create a new style. Most projects will only need a few button styles

In you AppDelegate’s application(_ , didFinishLaunchingWithOptions() call DesignableButton.setDesignableStyles()

Now in Interface Builder, drag a UIButton onto a view

Change the class to DesignableButton and the module to IHDesignableButton

Change the button type from System to Custom

Set the Button Style to “primary” or any other button style you’re created
