Filter assets stored on the local device

Problem:

I am trying to fetch only the PHAssets that are stored locally and not in iCloud

Issue:

I am looking to filter them out either in the following api calls:

1. [PHAssetCollection fetchAssetCollectionsWithType:type subtype:subtype options:fetchOption]
2. [PHAsset fetchAssetsInAssetCollection:group options:options];

What I tried and didn’t work:

I tried setting PHAssetSourceTypeUserLibrary in the PHFetchOptions

PHFetchOptions *fetchOption = [PHFetchOptions new];

fetchOption.includeAssetSourceTypes = PHAssetSourceTypeUserLibrary;

PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithType:type subtype:subtype options:fetchOption];

What works but is slow:

I used networkAccessAllowed = NO

in the PHImageRequestOptions when calling
[[PHImageManager defaultManager] requestImageDataForAsset: self options: imageRequestOptions resultHandler:^(NSData *imageData, NSString *dataUTI, UIImageOrientation orientation, NSDictionary *info)

then in the resultHandler I check if there is imageData or PHImageResultIsInCloudKey in the info dictionary.

That works but that’s an expensive operation, especially for a high number of assets in the iCloud (e.g. 10k)

Back to my question, is there a way to filter out the assets using either:

1. [PHAssetCollection fetchAssetCollectionsWithType:type subtype:subtype options:fetchOption]
   OR
2. [PHAsset fetchAssetsInAssetCollection:group options:options];

Thanks in advance,
Alex
