On Copy Action

[confusionhill]

Hello, I wanted to know if there's a delegate to detect on copy ? i wanted to debug to check why the image isn't copied

Thanks

no, you must handle by your self

yes. there are three handler functions inside MessagesViewController

open func collectionView(_: UICollectionView, shouldShowMenuForItemAt indexPath: IndexPath) -> Bool {
   guard let messagesDataSource = messagesCollectionView.messagesDataSource else { return false }

   if isSectionReservedForTypingIndicator(indexPath.section) {
     return false
   }

   let message = messagesDataSource.messageForItem(at: indexPath, in: messagesCollectionView)

   switch message.kind {
   case .text, .attributedText, .emoji, .photo:
     selectedIndexPathForMenu = indexPath
     return true
   default:
     return false
   }
 }

 open func collectionView(
   _: UICollectionView,
   canPerformAction action: Selector,
   forItemAt indexPath: IndexPath,
   withSender _: Any?)
   -> Bool
 {
   if isSectionReservedForTypingIndicator(indexPath.section) {
     return false
   }
   return (action == NSSelectorFromString("copy:"))
 }

 open func collectionView(_: UICollectionView, performAction _: Selector, forItemAt indexPath: IndexPath, withSender _: Any?) {
   guard let messagesDataSource = messagesCollectionView.messagesDataSource else {
     fatalError(MessageKitError.nilMessagesDataSource)
   }
   let pasteBoard = UIPasteboard.general
   let message = messagesDataSource.messageForItem(at: indexPath, in: messagesCollectionView)

   switch message.kind {
   case .text(let text), .emoji(let text):
     pasteBoard.string = text
   case .attributedText(let attributedText):
     pasteBoard.string = attributedText.string
   case .photo(let mediaItem):
     pasteBoard.image = mediaItem.image ?? mediaItem.placeholderImage
   default:
     break
   }
 }
