# beginLoadingImageData(for:)

Starts an asynchronous fetch for image data in all locations

## Declaration

```swift
func beginLoadingImageData(for client: (any ABImageClient)!) -> Int
```

## Parameters

- `client`: The object to be notified when the image finishes loading.

## Return Value

Return Value A nonzero tag for tracking. This tag is used by the cancelLoadingImageData(forTag:) method to cancel a fetch operation.

## Discussion

Discussion The client object should conform to the ABImageClient protocol. A consumeImageData(_:forTag:) message is sent to client when the fetch is done. Use the cancelLoadingImageData(forTag:) method if you need to cancel an asynchronous fetch.
