Get an error when trying to get all the photos from PHAssetCollection.fetchAssetCollections

问题

I want to get all the photos of my custom album. but instead what I get is the below error.

My Code

let collections:PHFetchResult = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: fetchOptions)

Error i get

"Error returned from daemon: Error Domain=com.apple.accounts Code=7 "(null)""

Any ideas on how to fix this?

回答1:

Based on the comments, I'm not entirely sure what the issue is but I hope this code could provide some assistance. Using .album rather than .smartAlbum could also be part of the issue.

private var fetchResult: PHFetchResult<PHAsset>!

func fetchOptions(_ predicate: NSPredicate?) -> PHFetchOptions {
            let options = PHFetchOptions()
            options.sortDescriptors = [ NSSortDescriptor(key: "creationDate", ascending: false) ]
        options.predicate = predicate
        return options
    }
}

    if let userLibraryCollection = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .smartAlbumUserLibrary, options: nil).firstObject {
        self.fetchResult = PHAsset.fetchAssets(in: userLibraryCollection, options: fetchOptions(NSPredicate(format: "mediaType = \(PHAssetMediaType.image.rawValue)")))
    } else {
        self.fetchResult = PHAsset.fetchAssets(with: .image, options: fetchOptions(nil))
    }
