QLThumbnailRequestCopyURL(_:)

Returns the URL of the document for which the thumbnail request is requested.

Declaration

func QLThumbnailRequestCopyURL(_ thumbnail: QLThumbnailRequest!) -> Unmanaged<CFURL>!

Parameters

  • thumbnail:

    The thumbnail request object.

Return Value

The URL identifying the document for which the thumbnail is requested. You should explicitly release the CFURL object when it is no longer needed.

Discussion

Thread-safety: This function should be called in the same thread as the thumbnail request is made in; generally, this is the same thread in which the GenerateThumbnailForURL callback was invoked.
