ios - 将 subview 添加到 collectionview 单元格 jsqmessagesviewcontroller

Question

我正在尝试向我的 collectionView (JSQMessagesViewController) 的每个单元格(消息)添加一个 subview 以显示我的消息时间，如下所示:

这是我的代码:

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = super.collectionView(collectionView, cellForItemAt: indexPath) as! JSQMessagesCollectionViewCell

        let message = messages[indexPath.item]

        let timeLabel = UILabel()
        timeLabel.frame = cell.textView.frame
        timeLabel.text = "abc"
        timeLabel.textColor = .blue

        cell.addSubview(timeLabel)

        if message.senderId == senderId { // 1
            cell.textView?.textColor = UIColor.black // 3
            cell.avatarImageView.image = self.avatars.0.image
            cell.avatarImageView.layer.cornerRadius = cell.avatarImageView.frame.size.height / 2
            cell.avatarImageView.clipsToBounds = true
        } else {

            cell.textView?.textColor = UIColor.black // 2
            cell.avatarImageView.image = self.avatars.1.image
            cell.avatarImageView.layer.cornerRadius = cell.avatarImageView.frame.size.height / 2
            cell.avatarImageView.clipsToBounds = true

        }

        return cell
    }

但它给我添加了 2 个标签:

为什么有两个标签？以及如何将此标签特别添加到消息的右下角？提前致谢!

检查 JSQMessagesCollectionViewCellIncoming.nib 和 JSQMessagesCollectionViewCellIncoming.nib 并根据您的需要调整 Cell 底部标签 使其看起来像您的设计。调整自动布局约束并完成。
