如何对专辑进行排序与​​Photos.app相同

Question

I want to sort albums the same way as Photos.app. I tried every possible PHFetchOptions for PHAssetCollection.fetchAssetCollections(with type: subtype:options:) :

• nil
• default without specifying sortDescriptors
• sortDescriptors with localizedTitle , title , startDate , endDate, estimatedAssetCount`

But none gives the same order as Photos.app.

Answer 1

// get Photos timeline
guard let timelineFetchResult = PHCollectionList.fetchMomentLists(with: .momentListCluster, options: nil).firstObject else { return }

// get Moments seperated by photos' creation date
let momentsFetchResult = PHAssetCollection.fetchMoments(inMomentList: timelineFetchResult, options: nil)

// get photos from every Moment
for index in 0 ..< momentsFetchResult.count {
    let moment = momentsFetchResult[index]
    let assetsFetchResult = PHAsset.fetchAssets(in: moment, options: nil)
    // ...
}
