如何为聊天气泡添加自定义菜单选项 - JsqMessage

Question

  

我正在使用JSQMessage进行聊天应用程序。在长按我能够   显示默认菜单选项（复制和删除）

  

现在的挑战是在菜单中添加另一个选项。任何帮助都将是   赞赏。

     

默认菜单选项的代码是

override func collectionView(_ collectionView: UICollectionView, shouldShowMenuForItemAt indexPath: IndexPath) -> Bool {
    super.collectionView(collectionView, shouldShowMenuForItemAt: indexPath)
    return true;
}

override func collectionView(_ collectionView: UICollectionView, canPerformAction action: Selector, forItemAt indexPath: IndexPath, withSender sender: Any?) -> Bool {

    let message = messageList[indexPath.item]
    switch action.description {
    case quickChatOptionDelete:
    // you can only delete your sent messages
    if message.senderId == strMemberID {
        return true
    } else {
        return false
    }
    case quickChatOptionCopy:
        return true
    case quickChatOptionUserList:
        return true
    default:
        return false
    }
}
    override func collectionView(_ collectionView: UICollectionView, performAction action: Selector, forItemAt indexPath: IndexPath, withSender sender: Any?) {

    let message = messageList[indexPath.item]

    switch action.description {
    case quickChatOptionDelete:
        if message.senderId == strMemberID {
            deleteMessage(messageId:message.messageId!)
        }
        break

    case quickChatOptionCopy: break
    case quickChatOptionUserList:
        print("list")
        break
    default: break
        // do nothing
    }
}

我相信您想要查看UIMenuController.shared.menuItems属性。您可以设置如下菜单项：

let items = [
        UIMenuItem(
            title: "Copy",
            action: copyTextAction),
        UIMenuItem(
            title: "First Name",
            action: firstName),
        UIMenuItem(
            title: "Last Name",
             action: lastName),
        UIMenuItem(
            title: "Email",
            action: email),
        UIMenuItem(
            title: "Home Phone",
            action: homePhone),
        UIMenuItem(
            title: "Mobile Phone",
            action: mobilePhone),
        UIMenuItem(
            title: "Street Address",
            action: streetAddress),
        UIMenuItem(
            title: "City",
            action: city),
        UIMenuItem(
            title: "State",
            action: state),
        UIMenuItem(
            title: "Zip",
            action: zip)
    ]
    UIMenuController.shared.menuItems = items
