Options used when retrieving objects of type PHAsset, PHCollection, PHAssetCollection, or PHCollectionList.

PHFetchResult

An ordered list of PHObject objects.

PHFetchResultChangeDetails

Differences between a fetch previously performed and what would be the results if the same fetch were performed now.

PHImageKeys

Constants indicating results of image loading. Used with RequestImageForAsset(PHAsset, CGSize, PHImageContentMode, PHImageRequestOptions, PHImageResultHandler), defines the keys and values passed to the PHImageResultHandler .

PHObject

Abstract class for elements within the Photos library; subclasses are individual PHAssets, composite PHCollections, or not-yet-created PHObjectPlaceholders.

PHObjectChangeDetails

Holds information between a fetched Photos object and the state of that asset or collection within the Photos library.

PHObjectPlaceholder

A read-only proxy for an PHAsset or PHCollectionList that has not yet been created, but will be created via a sequence of change requests.

PHPhotoLibrary

The entire set of data managed by the Photos app. This includes both locally stored assets and, if user-enabled, assets stored in iCloud.

Remarks

The Photos namespace, introduced in iOS 8, allows application developers to manipulate photos and videos managed by the Photos app, including iCloud photos.

Capabilities of the Photos namespace include:

  • Fetching assets and collections of assets.
  • Editing assets, including support for reverting changes.
  • Observing changes in assets.
  • Acces to Photos-provided data such as the Moments hierarchy, high-framerate video captures, whether photos were captured with panorama or burst mode, etc..
  • Loading thumbnails and caching assets.
