Discussion
When you use the request(withResourceFileURLs:placeholderImage:targetSize:contentMode:resultHandler:) method to asynchronously load a Live Photo from resource files, the method returns a numeric identifier for the request. To cancel the request before it completes, provide the identifier when calling the cancelRequest(withRequestID:) method.
