Yes, you can open a remote PDF without downloading the entire file first by using the PDFHttpStream class instead of downloading the file to disk manually.

  1. Instantiate PDFHttpStream.
  2. Call the open: method, passing the remote URL string and a local path for the cache file.

The SDK handles the HTTP requests and caching internally, allowing the UI to display content as soon as the initial bytes are received.

Caveat: The cache file path you provide must be writable. Using NSTemporaryDirectory() is the standard approach, but ensure the file name is unique if you are opening multiple documents simultaneously to avoid conflicts.
