Class

PHLivePhotoView

A view that displays a Live Photo—a picture that also includes motion and sound from the moments just before and after its capture.

Declaration

iOS, tvOS
@interface PHLivePhotoView : UIView
macOS
@interface PHLivePhotoView : NSView

Overview

Use a Live Photo view to display the photo and control playback of its motion and sound content. In iOS and tvOS, you can obtain Live Photo objects from the Photos library, using the UIImagePickerController or PHAsset and PHImageManager classes, or by creating one from asset resources exported from a Photos library. In macOS, Live Photo objects are available only when editing Live Photo content in a photo editing extension that runs in the Photos app—see the PHContentEditingInput class to access Live Photo content in an editing session.

By default, a Live Photo view uses its own gesture recognizer to allow the user to play the motion and sound content of a Live Photo with the same interactions and visual effects seen in the Photos app. To customize this gesture recognizer—for example, to install it on a different view for proper event handling in your app’s view hierarchy—use the playbackGestureRecognizer property.

To animate the view briefly to hint that a picture is a Live Photo, use the startPlaybackWithStyle: method with the PHLivePhotoViewPlaybackStyleHint option.

Responding to Playback Events

PHLivePhotoViewDelegate

The PHLivePhotoViewDelegate protocol describes messages sent by a PHLivePhotoView instance in response to playback events when playing the motion and sound content associated with a Live Photo. To receive these messages, implement the methods in this protocol in one of your controller objects and assign that object to the delegate property of a Live Photo view.
