+
+Sometimes it's useful to know whether or not the device has a screen reader that is currently active. The
+`AccessibilityInfo` API is designed for this purpose. You can use it to query the current state of the
+screen reader as well as to register to be notified when the state of the screen reader changes.
+
+Here's a small example illustrating how to use `AccessibilityInfo`:
+
+```javascript
+class ScreenReaderStatusExample extends React.Component {
+  state = {
+    screenReaderEnabled: false,
+  }
+
+  componentDidMount() {
+    AccessibilityInfo.addEventListener(
+      'change',
+      this._handleScreenReaderToggled
+    );
+    AccessibilityInfo.fetch().done((isEnabled) => {
+      this.setState({
+        screenReaderEnabled: isEnabled
+      });
+    });
+  }
+
+  componentWillUnmount() {
+    AccessibilityInfo.removeEventListener(
+      'change',
+      this._handleScreenReaderToggled
+    );
+  }
+
+  _handleScreenReaderToggled = (isEnabled) => {
+    this.setState({
+      screenReaderEnabled: isEnabled,
+    });
+  }
+
+  render() {
+    return (
+      <View>
+        <Text>
+          The screen reader is {this.state.screenReaderEnabled ? 'enabled' : 'disabled'}.
+        </Text>
+      </View>
+    );
+  }
+}
+```

+## Methods
+
+### `fetch()`
+
+```javascript
+static fetch()
+```
+
+
+Query whether a screen reader is currently enabled. Returns a promise which
+resolves to a boolean. The result is `true` when a screen reader is enabled
+and `false` otherwise.
+

+
+
+---
+
+### `addEventListener()`
+
+```javascript
+static addEventListener(eventName, handler)
+```
+
+
+Add an event handler. Supported events:
+
+- `change`: Fires when the state of the screen reader changes. The argument
+  to the event handler is a boolean. The boolean is `true` when a screen
+  reader is enabled and `false` otherwise.
+- `announcementFinished`: iOS-only event. Fires when the screen reader has
+  finished making an announcement. The argument to the event handler is a dictionary
+  with these keys:
+    - `announcement`: The string announced by the screen reader.
+    - `success`: A boolean indicating whether the announcement was successfully made.
+
+
+
+
+---
+
+### `setAccessibilityFocus()`
+
+```javascript
+static setAccessibilityFocus(reactTag)
+```
+
+
+iOS-Only. Set accessibility focus to a react component.
+
+

+
+---
+
+### `announceForAccessibility()`
+
+```javascript

+```
+
+
+iOS-Only. Post a string to be announced by the screen reader.

+## Methods
+
+### `showActionSheetWithOptions()`
+
+```javascript
+static showActionSheetWithOptions(options, callback)
+```
+
+
+Display an iOS action sheet. The `options` object must contain one or more
+of:
+
+- `options` (array of strings) - a list of button titles (required)
+- `cancelButtonIndex` (int) - index of cancel button in `options`
+- `destructiveButtonIndex` (int) - index of destructive button in `options`
+- `title` (string) - a title to show above the action sheet
+- `message` (string) - a message to show below the title
+
+The 'callback' function takes one parameter, the zero-based index
+of the selected item.
+
+Minimal example:
+
+```
+ActionSheetIOS.showActionSheetWithOptions({
+  options: ['Remove', 'Cancel'],
+  destructiveButtonIndex: 1,
+  cancelButtonIndex: 0,
+},
+(buttonIndex) => {
+  if (buttonIndex === 1) { // destructive action }
+});
+```
+
+
+
+
+
+---
+
+### `showShareActionSheetWithOptions()`
+
+```javascript
+static showShareActionSheetWithOptions(options, failureCallback, successCallback)
+```
+
+
+Display the iOS share sheet. The `options` object should contain
+one or both of `message` and `url` and can additionally have
+a `subject` or `excludedActivityTypes`:
+
+- `url` (string) - a URL to share
+- `message` (string) - a message to share
+- `subject` (string) - a subject for the message
+- `excludedActivityTypes` (array) - the activities to exclude from the ActionSheet
+
+NOTE: if `url` points to a local file, or is a base64-encoded
+uri, the file it points to will be loaded and shared directly.
+In this way, you can share images, videos, PDF files, etc.
+
+The 'failureCallback' function takes one parameter, an error object.
+The only property defined on this object is an optional `stack` property
+of type `string`.
+
+The 'successCallback' function takes two parameters:
+
+- a boolean value signifying success or failure
+- a string that, in the case of success, indicates the method of sharing
+
+
