如何在Flutter游戏中禁用iOS 13+的三指点击/滑动手势？

你之前的操作无效，核心原因是：iOS的三指编辑手势会检查接收触摸事件的最上层UIResponder的editingInteractionConfiguration属性，而Flutter应用中实际处理触摸的是FlutterView，不是你重写的FlutterViewController。

下面是两种可行的解决方案：

方案一：子类化FlutterView并替换 #

创建自定义FlutterView子类，重写editingInteractionConfiguration属性，再让你的FlutterViewController使用该子类视图：

import Flutter
import UIKit

class DisableEditGestureFlutterView: FlutterView {
    @available(iOS 13.0, *)
    override var editingInteractionConfiguration: UIEditingInteractionConfiguration {
        .none
    }
}

class GameFlutterVC: FlutterViewController {
    override func loadView() {
        // 替换为自定义FlutterView
        let flutterView = DisableEditGestureFlutterView(frame: UIScreen.main.bounds)
        self.view = flutterView
    }

    override func viewWillAppear(_ animated: Bool) {
        print("This gets printed.");
        super.viewWillAppear(animated)
    }
}

方案二：全局方法交换（推荐） #

如果需要全应用禁用，用Method Swizzling直接修改FlutterView的属性实现，无需逐个修改视图控制器：

import Flutter
import UIKit

@UIApplicationMain
class AppDelegate: FlutterAppDelegate {
    override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // 全局禁用iOS 13+三指编辑手势
        if #available(iOS 13.0, *) {
            guard let originalMethod = class_getInstanceMethod(FlutterView.self, #selector(getter: UIResponder.editingInteractionConfiguration)),
                  let swizzledMethod = class_getInstanceMethod(AppDelegate.self, #selector(getter: AppDelegate.swizzledEditingConfig)) else {
                return super.application(application, didFinishLaunchingWithOptions: launchOptions)
            }
            method_exchangeImplementations(originalMethod, swizzledMethod)
        }
        
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    @available(iOS 13.0, *)
    @objc private var swizzledEditingConfig: UIEditingInteractionConfiguration {
        .none
    }
}

补充说明 #

• 两种方案都确保实际接收触摸的FlutterView返回.none，系统就不会触发三指编辑相关手势。
• 方案二更适合全局禁用场景，无需修改多个视图控制器。
