beginLoadingImageData(for:)

Starts an asynchronous fetch for image data in all locations

Declaration

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

Parameters

  • client:

    The object to be notified when the image finishes loading.

Return Value

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

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.
