JSQ mesage-Swift 3“；按发送按钮“；

我正在尝试使用JSQ消息进行简单的聊天。
每当我使用“发送”按钮时，应用程序就会崩溃。
它在终端中运行良好，但在我希望它显示在视图中后，我不断收到以下消息：

由于未捕获异常“NSInternalInconsistencyException”而终止应用程序，原因：“错误！子类中未实现必需的方法。需要实现-[JSQMessagesViewController按Send按钮：withMessageText:senderId:senderDisplayName:date:]

这是我的控制器：

使用：Swift 3.0和JSQMessagesViewController 7.3.4

override func didPressSend(_ button: UIButton!, withMessageText text: String!, senderId: String!, senderDisplayName: String!, date: Date!) {
        let message = JSQMessage(senderId: senderId, senderDisplayName: senderDisplayName, date: date, text: text)
        //ex: self.messages.append(message!)
        self.finishSendingMessage()
    }

// MARK: - JSQMessage
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    code
}

override func collectionView(_ collectionView: JSQMessagesCollectionView!, avatarImageDataForItemAt indexPath: IndexPath!) -> JSQMessageAvatarImageDataSource! {
    code
}

override func collectionView(_ collectionView: JSQMessagesCollectionView!, messageBubbleImageDataForItemAt indexPath: IndexPath!) -> JSQMessageBubbleImageDataSource! {
    code
}

override func collectionView(_ collectionView: JSQMessagesCollectionView!, messageDataForItemAt indexPath: IndexPath!) -> JSQMessageData! {
    code
}

override func didPressSend(_ button: UIButton!, withMessageText text: String!, senderId: String!, senderDisplayName: String!, date: Date!) {

谢谢。成功了。现在我只需要弄清楚，如何在BubbleImage中显示消息。有什么想法吗

删除“覆盖”字时，Xcode错误消失

但是，这会带来问题

必须重写每个方法。 请小心如？还有!

摆脱

键入函数参数后，它们不可为null。至少在最新的JSQMessagesViewController版本中是这样。我试过了，但对您没有帮助⌘-单击
JSQMessagesViewController
并检查那里如何定义
didPressSendButton
？我在更新到Swift 3之前工作过。这可能是原因吗？摆脱
