UI Components​

  • linkPreveiw: An LMFeedLinkPreview used for displaying the link preview within the cell.

Data Variables​

  • delegate: A weak reference to an instance of LMFeedLinkProtocol to handle link preview tap events.
  • postURL: Optionally stores the URL string associated with the link preview in the post.

Methods​

  • configure(): Configures the cell with the provided data and sets up the delegate for cell interactions.
