Functionality​

Protocols​

LMFeedPostDocumentCellProtocol​

Conforms to LMPostWidgetTableViewCellProtocol. It includes functions for handling interactions within the document cell:

  • didTapShowMoreDocuments(for indexPath: IndexPath): Invoked when the user taps the "See More" button to view additional documents.
  • didTapDocument(with url: URL): Called when a document preview is tapped.

UI Components​

  • documentContainerStack: An LMFeedStackView used to vertically stack document preview views.
  • seeMoreDocumentsButton: An LMFeedButton for showing more documents if they exceed the predefined limit.

Data Variables​

  • delegate: A weak reference to an instance conforming to LMFeedPostDocumentCellProtocol for handling user interactions.
  • indexPath: Optionally stores the IndexPath of the cell within the tableView, useful for delegate callbacks.

Methods​

  • configure(): Configures the cell with the data and sets the delegate. It prepares the document previews and sets the post Text accordingly.

Action Handlers​

  • didTapSeeMoreDocuments(): The selector method for the "See More" button's tap action. It checks if the indexPath is set and notifies the delegate to handle the event.
