# isNetworkAccessAllowed

A Boolean value that specifies whether Photos can download the requested asset resource data from iCloud.

```
var isNetworkAccessAllowed: Bool { get set }
```

## Discussion

If `true`, and the requested resource data is not stored on the local device, Photos downloads that data from iCloud. To be notified of the download’s progress, use the [`progressHandler`](/documentation/Photos/PHAssetResourceRequestOptions/progressHandler) property to provide a block that Photos calls periodically while downloading the resource data. If `false` (the default), and the resource data is not on the local device, Photos calls the `completionHandler` block you provided in your request, with an `NSError` object indicating that the resource requires network access.
