Check given PHAsset is iCloud asset?

Question

I'm trying to get PhAsset object. I want to segregate iCloud assets. Here is my code,

PHFetchResult *cloudAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:nil];

[cloudAlbums enumerateObjectsUsingBlock:^(PHAssetCollection *collection, NSUInteger idx, BOOL *stop){
    if(collection != nil){

        PHFetchResult *result = [PHAsset fetchAssetsInAssetCollection:collection options:fetchOptions];
        [result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop)
         {
            // check asset is iCloud asset 

         }];
    }

}];

Please tell me how to find the PHAsset is iCloud asset?

Answer 1

It's a bit kind of hack, where I had to dig out the resource array and debug to find out my required information. But it works. Although this is an undocumented code and I'm not sure whether apple will reject the app because of this or not. Give it a try and see what happens!

// asset is a PHAsset object for which you want to get the information    
NSArray *resourceArray = [PHAssetResource assetResourcesForAsset:asset];
BOOL bIsLocallayAvailable = [[resourceArray.firstObject valueForKey:@"locallyAvailable"] boolValue]; // If this returns NO, then the asset is in iCloud and not saved locally yet

You can also get some other useful information from asset resource, such as - original filename, file size, file url, etc.
