我如何在 MessageKit 中設置 messageViewController 的偏移量？

Question

我的 Messagekit 的messageViewController正在顯示這樣的消息，我如何設置消息的偏移量以顯示在導航欄下方？

我的 messageViewController 布局代碼

 func configureView(){

    scrollsToBottomOnKeyboardBeginsEditing = true // default false
    maintainPositionOnKeyboardFrameChanged = true // default false

let layout = messagesCollectionView.collectionViewLayout as? MessagesCollectionViewFlowLayout
layout?.sectionInset = UIEdgeInsets(top: 1, left: 8, bottom: 1, right: 8)

// Hide the outgoing avatar and adjust the label alignment to line up with the messages
layout?.setMessageOutgoingAvatarSize(.zero)
layout?.setMessageOutgoingMessageTopLabelAlignment(LabelAlignment(textAlignment: .right, textInsets: UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 8)))
layout?.setMessageOutgoingMessageBottomLabelAlignment(LabelAlignment(textAlignment: .right, textInsets: UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 8)))

// Set outgoing avatar to overlap with the message bubble
layout?.setMessageIncomingMessageTopLabelAlignment(LabelAlignment(textAlignment: .left, textInsets: UIEdgeInsets(top: 0, left: 18, bottom: outgoingAvatarOverlap, right: 0)))
layout?.setMessageIncomingAvatarSize(CGSize(width: 30, height: 30))
layout?.setMessageIncomingMessagePadding(UIEdgeInsets(top: -outgoingAvatarOverlap, left: -18, bottom: outgoingAvatarOverlap, right: 18))

layout?.setMessageIncomingAccessoryViewSize(CGSize(width: 30, height: 30))
layout?.setMessageIncomingAccessoryViewPadding(HorizontalEdgeInsets(left: 8, right: 0))
layout?.setMessageIncomingAccessoryViewPosition(.messageBottom)
layout?.setMessageOutgoingAccessoryViewSize(CGSize(width: 30, height: 30))
layout?.setMessageOutgoingAccessoryViewPadding(HorizontalEdgeInsets(left: 0, right: 8))

messagesCollectionView.messagesLayoutDelegate = self
messagesCollectionView.messagesDisplayDelegate = self
}

如果我隱藏導航欄，它會像這樣顯示

Answer 1

你在使用IQKeyboardManager嗎？

如果是這樣，那么您只需在AppDelegate didFinishLaunchingWithOptions中添加以下內容即可解決此問題：

IQKeyboardManager.shared.disabledDistanceHandlingClasses.append(YourChatVC.self)

Answer 2

將內容插入填充添加到 messagesCollectionView

override func viewDidLoad() {
    super.viewDidLoad()

   self.messagesCollectionView.contentInset = UIEdgeInsets(top: 70, left: 0, bottom: 70, right: 0)
}

Answer 3

您需要在 viewDidLayoutSubviews 中更改 messagesCollectionView contentSize
