This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@capacitor-community/app-icon) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Before Starting

This plugin only changes the main app icon on the device homescreen. The icon in springboard and in other areas of iOS will not change and continue to show the original.

Changing the app icon is only allowed when the app is in the foreground.

Installation

npm install @capacitor-community/app-icon
npx cap sync

Capacitor 2.x

For Capacitor 2.x projects, you will need to install a version less than 2.0.0. You can do that by specifying the version in your package.json or installing like this.

npm i @capacitor-community/app-icon@1.1.0

## Configuration

### Add Alternate Icons

The alternate icons need to be included within the app bundle and referenced in the iOS project `Info.plist` prior to using this plugin. It is not possible to switch to any icon on the fly without adding it to the iOS project first.

Add the alternate icons directly to your iOS project or in a subdirectory.

### Setup Info.plist

Add the `CFBundleIcons` key to `Info.plist` with `CFBundleAlternateIcons` dictionary. Each alternate icon needs to be specified.

<img src="https://github.com/capacitor-community/app-icon/blob/main/media/xcode_project.png" width="500px" />

Providing every resolution for each alternative is not required. By including the icon with the highest supported resolution, iOS will handle the other resolutions by scalling down the large one provided.

From Apple:
> When specifying icon filenames, it is best to omit any filename extensions. Omitting the filename extension lets the system automatically detect high-resolution (@2x) versions of your image files using the standard-resolution image filename. If you include filename extensions, you must specify all image files (including the high-resolution variants) explicitly. The system looks for the icon files in the main resources directory of the bundle.

```xml
<key>CFBundleIcons</key>
<dict>
  <key>CFBundleAlternateIcons</key>
  <dict>
    <!-- The names to reference in your code -->
    <key>ionic-icon</key>
    <dict>
      <key>UIPrerenderedIcon</key>
      <true/>
      <key>CFBundleIconFiles</key>
      <array>
        <!-- Filenames-->
        <string>ionic-icon</string>
      </array>
    </dict>
    <!-- ... additional alternates if any ... -->
  </dict>
</dict>

Supporting iPad

For iPad specific version of an icon, there is an additional key to add in Info.plist.

<key>CFBundleIcons~ipad</key>
<dict>
  <!-- same as above  -->
</dict>

Usage

import { AppIcon } from '@capacitor-community/app-icon';
