# VoiceOver
|
|
|
|
VoiceOver is an Accessibility feature available on Apple platforms. It provides
|
|
an interface between your app and your blind or low-vision users. In short, it's
|
|
a screen reader.
|
|
|
|
## Overview
|
|
|
|
[Activating VoiceOver](#Activate-VoiceOver) fundamentally changes the touch
|
|
interface of an iOS device, so when you activate it, you need to know these
|
|
basic commands to navigate:
|
|
|
|
- VoiceOver focuses an item on the screen and speaks it to the user.
|
|
- To navigate between items, you can either flick left/right to go to the
|
|
previous/next item, or you can drag your finger around the screen.
|
|
- Double tapping anywhere on the screen activates the item (no need to double
|
|
tap exactly on the item on the screen).
|
|
- Items have a label (describing the item) and can have among others:
|
|
- traits (describing the item: a header, a button, selection state, etc.);
|
|
- a hint (describing how to interact with the item).
|
|

|
The following video is a great summary. The content is succinct, high quality
|
|
and up-to-date, even though the video quality is low and the demo is on an
|
|
iPhone 3GS.

## Activate VoiceOver
|
|
|
|
Go to `Settings > General > Accessibility > VoiceOver` and toggle the top
|
|
switch.
|
|
|
|
Alternatively, if you are activating/deactivating VoiceOver often, I'd advise
|
|
to set it as the Accessibility Shortcut. When enabled, a triple tap on the Home
|
|
button will toggle VoiceOver ON and OFF from anywhere.
|
|
```
|
|
Settings > General > Accessibility > Accessibility Shortcut
|
|
```
