我遇到了一个问题。在 iOS 13 之前，AssetCollection 中有 15 个 smartAlbum 类型的相册，但在 iOS 13 中code>，数字变成了14。 相机胶卷从其中消失了。
这里是获取相册的代码:
func loadAlbums() {
var albums:[AlbumModel] = [AlbumModel]()
let options = PHFetchOptions()
let userAlbums = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .any, options: options)
userAlbums.enumerateObjects { [weak self] (object: AnyObject!, count: Int, stop: UnsafeMutablePointer) in
if object is PHAssetCollection {
let obj: PHAssetCollection = object as! PHAssetCollection
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
fetchOptions.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.image.rawValue)
if let arrayAllowedTypes = self?.arrayAllowedSubtypesRawValues, arrayAllowedTypes.contains(obj.assetCollectionSubtype.rawValue) {
let photos = PHAsset.fetchAssets(in: obj, options: fetchOptions)
let newAlbum = AlbumModel(name: obj.localizedTitle ?? String.empty, count: photos.count, collection:obj, firstAsset: photos.firstObject)
albums.append(newAlbum)
}
}
}
allowedAlbums = albums
selectedAlbum = albums.first(where: { (album) -> Bool in
album.collection.assetCollectionSubtype.rawValue == 209 // Camera roll
})
}
和结果iOS 13:

我的问题是:相机胶卷(所有照片)相册现在位于哪里？我怎样才能得到它？
最佳答案
是的，苹果似乎在 iOS 13 中删除了相机胶卷相册:https://appletoolbox.com/heres-everything-new-in-photos-and-camera-in-ios-13/
iOS 13 中的相机胶卷(所有照片)位置已更改。它已从“相册”选项卡中删除
您的209魔数(Magic Number)表示PHAssetCollectionSubtypeSmartAlbumUserLibrary。
您可以使用PHAssetCollectionSubtypeSmartAlbumRecentlyAdded子类型来获取“最近”相册，并默认选择“最近”。
