ImageAlertAction

ImageAlertAction is a UIAlertAction extension that adds support for an image in the action's button.

Example

To run the example project, clone the repository, and run pod install from the Example directory first.

Installation

ImageAlertAction is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ImageAlertAction'

Usage

Adding an image to a UIAlertAction

Create a UIAlertAction like you'd do normally, and pass an image to the image parameter. This will add the image on the left of the action's button.

let settings = UIAlertAction(
  title: "Settings",
  image: #imageLiteral(resourceName: "settings"),
  style: .default
)

Keeping the UIImage's original color

By default, the image provided will be treated as a template, and will be recolored based on the action's style. If you want to draw the original image, you can pass an image with an explicit rendering mode.

let settingsImage = #imageLiteral(resourceName: "settings").withRenderingMode(.alwaysOriginal) 
let settings = UIAlertAction(
  title: "Settings",
  image: settingsImage,
  style: .default
)

Accessing the added UIImage

As with the title and style, you can access the image set on the UIAlertAction.

let settings = UIAlertAction(
  title: "Settings",
  image: #imageLiteral(resourceName: "settings"),
  style: .default
)
settings.image // returns an optional UIImage

Adding a checkmark

You can also show a check mark on actions via isChecked.

let settings = UIAlertAction(
  title: "Settings",
  image: #imageLiteral(resourceName: "settings"),
  isChecked: true
  style: .default
)
settings.isChecked // returns a Bool

Presenting the UIAlertController

To present a UIAlertController containing the UIAlertAction, nothing changes.

let alertController = UIAlertController(
  title: "Title",
  message: "Message",
  preferredStyle: .actionSheet
)

let settings = UIAlertAction(
  title: "Settings",
  image: #imageLiteral(resourceName: "settings"),
  style: .default
)
alertController.addAction(settings)

present(alertController, animated: true)
