# 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](https://cocoapods.org). To install
it, simply add the following line to your Podfile:
```ruby
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.
```swift
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.
```swift
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`.
```swift
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`.
```swift
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.
```swift
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)
```
