# Apple Pencil

## Overview

Apryse's iOS SDK has full support for the Apple Pencil. This guide describes the various settings and how to change them.

## Annotating without an annotation tool selected

When the user does not have an annotation tool selected (ie the active tool is the [pan tool](https://sdk.apryse.com/api/ios/Classes/PTPanTool.html)), the pencil can either draw an ink annotation (default behavior), or act as a finger touch. This behavior can be changed using the [`applePencilDrawsInk`](https://sdk.apryse.com/api/ios/Classes/PTToolsSettingsManager.html#/c:objc\(cs\)PTToolsSettingsManager\(py\)applePencilDrawsInk).

## Annotating with **only** the pencil

When the user has an Apple Pencil paired with the device, it is possible to restrict annotation creation to only pencil touches. This allows the user to conveniently scroll with a single finger. It is also useful in preventing a user's palm from inadvertently creating an annotation.

The `PTToolsSettingsManager`'s [`pencilInteractionMode`](https://sdk.apryse.com/api/ios/Classes/PTToolsSettingsManager.html#/c:objc\(cs\)PTToolsSettingsManager\(py\)pencilInteractionMode) controls how touches are interpreted when an Apple Pencil is paired:

| Mode                                     | Description                                                                |
| ---------------------------------------- | -------------------------------------------------------------------------- |
| `PTPencilInteractionModeFingerAndPencil` | Finger touches will annotate (default on iOS 13)                           |
| `PTPencilInteractionModePencilOnly`      | Finger touches will **not** annotate. Single finger can be used to scroll. |
| `PTPencilInteractionModeSystem`          | Follows the system setting (default on iOS 14+)                            |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/ios/annotation/apple-pencil.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
