How to set up and use action extensions on iPhone and iPad

Action extensions, part of extensibility, let apps share their functionality with other apps installed on your iPhone or iPad. For example, you can use a 1Password action extension to log in to your Twitter account from inside Tweetbot. You can use a Bing action extension to translate a web page inside Safari. You can use a PDF Expert extension to turn an article into a document. You can even use an app like Workflow to create your own, custom action extensions. All you have to do is turn them on, set them up the way you like, and then put them to use!

Action extensions will show up in Share sheet of any app that supports them. However, the Share sheet will only show action extensions that support the app's content type. For example, 1Password and Things will show up in Safari but not in the Photos app. Since most action extensions are available in Safari, that's the best place to enable, disable, or reorder them.

How to enable action extensions on iPhone and iPad

  1. Launch Safari on your iPhone or iPad.
  2. Navigate to any web page and tap on the Share button in the bottom navigation.
  3. Scroll all the way through the bottom row of icons.

  1. Tap on the More button.
  2. Toggle On any action extensions you have that you'd like to use. When the switch is green that means the extension is on.
  3. Tap Done to finish.
