# NSTextAttachmentViewProvider

A container object that associates a text attachment at a particular document location with a view object.

## Declaration

```swift
class NSTextAttachmentViewProvider
```

## Overview

Overview Use NSTextAttachmentViewProvider when you need to represent document locations in terms of an NSTextLocation or an NSTextRange or you want to support view-based text attachments. The view provider controls the view placement and layout without requiring view classes to be aware of the text attachment coordination using a NSTextLayoutManager in macOS 12 or iOS 15 and later.

## Topics

### Initializing a text attachment view

- [init(textAttachment:parentView:textLayoutManager:location:)](uikit/nstextattachmentviewprovider/init(textattachment:parentview:textlayoutmanager:location:).md)

### Defining the contents

- [textAttachment](uikit/nstextattachmentviewprovider/textattachment.md)
- [textLayoutManager](uikit/nstextattachmentviewprovider/textlayoutmanager.md)
- [tracksTextAttachmentViewBounds](uikit/nstextattachmentviewprovider/trackstextattachmentviewbounds.md)
- [view](uikit/nstextattachmentviewprovider/view.md)

### Defining a custom view hierarchy

- [loadView()](uikit/nstextattachmentviewprovider/loadview().md)

### Determining the Attachment’s Bounds

- [attachmentBounds(for:location:textContainer:proposedLineFragment:position:)](uikit/nstextattachmentviewprovider/attachmentbounds(for:location:textcontainer:proposedlinefragment:position:).md)
