向JSQMessagesViewControllerCell添加自定义菜单选项

import JSQMessagesViewController

extension JSQMessagesViewControllerCell {
    // 添加自定义菜单选项
    func addCustomMenuOptions() {
        let customAction = UIAction(title: "自定义操作", image: nil) { action in
            // 执行自定义操作
            self.customActionHandler()
        }
        
        let menu = UIMenu(title: "", children: [customAction])
        UIMenuController.shared.menuItems = [menu]
    }
    
    // 自定义操作的处理方法
    func customActionHandler() {
        // 执行自定义操作
        print("执行自定义操作")
    }
}

// 在需要显示菜单的地方注册自定义菜单选项
class MyViewController: JSQMessagesViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 注册自定义菜单选项
        registerForPreviewing(with: self, sourceView: collectionView)
    }
}

// 实现菜单选项的回调方法
extension MyViewController: UIViewControllerPreviewingDelegate {
    func previewingContext(_ previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
        return nil
    }
    
    func previewingContext(_ previewingContext: UIViewControllerPreviewing, commit viewControllerToCommit: UIViewController) {
        // 处理菜单选项的选择
        if let cell = previewingContext.sourceView as? JSQMessagesViewControllerCell {
            cell.customActionHandler()
        }
    }
}
