ios - Dose Flutter 同时支持scenedelegate 和sirishortcut 吗？

问题描述

我正在尝试制作一个应用程序以在颤动中使用 siri 快捷方式。但它不起作用。我想要做的是尝试从颤动中显示 iOS 屏幕以使用 MethodChannle 和 ivokeMethod。什么时候可以移动我也注册了siri快捷方式。

在 AppDelegate 中实现 MethodChannel&invokeMethod 的代码。有用。

当我在项目中添加到 SceneDelegate 时，它​​崩溃并显示这些错误

错误是

[VERBOSE-2:ui_dart_state.cc(186)] Unhandled Exception: MissingPluginException(No implementation found for method sample/aaa on channel sample/aaa)

#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:156:7)

#1      _MyHomePageState._launchNativeScreen (package:flutter_to_ojt/main.dart:36:5)

为什么我添加到 SceneDelegate 是在其中实现 siri 快捷方式代码。我认为这是由 SceneDelegate 引起的，因为当我仅构建 AppDelegate 应用程序时，它可以工作。

让我写下我的代码

·扑

'''class _MyHomePageState extends State<MyHomePage> {
MethodChannel _channel = const MethodChannel('sample/aaa');


Future _launchNativeScreen() async {
await _channel.invokeMethod('sample/aaa');} //MethodChannle to Xcode

enter code here
@override Widget build(BuildContext context) {

var listItem = ["one", "Two", "three"];
return Scaffold(
  appBar: AppBar(
   
    title: Text(widget.title),
  ),
  body: ListView.builder(itemBuilder: (BuildContext cotext, int index) {
    return Container(
      decoration: BoxDecoration (
        border: Border (
          bottom: BorderSide(color: Colors.black38),
        ),
      ),
      child: ListTile(
        leading: const Icon(Icons.arrow_forward_ios_sharp),
        title: Text('$index'),
        subtitle: Text('&listItem'),
        onTap: () { _launchNativeScreen();
          print('ここまできてる');  },
      ));},
      itemCount: listItem.length,
  ), 
);}}

・AppDelegate 中的 Xcode

'''
@interface AppDelegate()
@property (nonatomic, strong) UINavigationController *navigationController;
@end

@implementation AppDelegate
FlutterResult _flutterResult;

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
printf("AppDelegate");

[GeneratedPluginRegistrant registerWithRegistry:self];
[self setiOSChannel]; //connect to flutter
Override point for customization after application launch.

return [super application:application didFinishLaunchingWithOptions:launchOptions];}

- (void) setiOSChannel {
printf("setiOSChannel");

FlutterViewController * flutterController =(FlutterViewController*)self.window.rootViewController;

//setup navigation
self.navigationController = [[UINavigationController alloc] initWithRootViewController:flutterController];
self.window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];
self.window.rootViewController = self.navigationController;
[self.navigationController setNavigationBarHidden:YES animated:YES];
[self.window makeKeyWindow];

FlutterMethodChannel * methodChannle = [FlutterMethodChannel methodChannelWithName:@"sample/aaa" binaryMessenger:flutterController.binaryMessenger];

 [methodChannle setMethodCallHandler:^(FlutterMethodCall * call, FlutterResult result) {
   if ([call.method isEqual: @"sample/aaa"] ) {
        printf("sample/aaa");
        //push遷移ボタンコード
        UIStoryboard* storyboard = [UIStoryboard storyboardWithName: @"Main" bundle: nil];
        UIViewController* vc = [storyboard instantiateViewControllerWithIdentifier:@"MeasureViewController"];

        [self.navigationController pushViewController:vc animated:YES];
      printf("push遷移");


    }
}];}
'''

・SceneDelegate 中的 Xcode

'''enter code here
@interface SceneDelegate () @end
@implementation SceneDelegate
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions  API_AVAILABLE(ios(13.0)){

printf("willConnectToSession");
NSUserActivity * act = [connectionOptions.userActivities.allObjects firstObject];

if (act != nil){
    _sirishortcut = YES;
      [self scene:(UIScene *)scene continueUserActivity:(NSUserActivity *)act];
}

- (void)sceneDidDisconnect:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneDidBecomeActive:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneWillResignActive:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneWillEnterForeground:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneDidEnterBackground:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneDidEnterBackground:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}

- (void)sceneDidEnterBackground:(UIScene *)scene  API_AVAILABLE(ios(13.0)){
}
enter code here
- (void)scene:(UIScene *)scene continueUserActivity:(NSUserActivity *)userActivity  API_AVAILABLE(ios(13.0)){

//storyboard取得
UIStoryboard* storyboard = [UIStoryboard storyboardWithName: @"Main" bundle: nil];

//storyboardID指定
UIViewController* vc = [storyboard instantiateViewControllerWithIdentifier:@"MeasureViewController"];

//画面遷移のアニメーションを設定
vc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

//UINavigationControllerに向けてモーダル遷移
//[[self window presentViewController:nc animated:YES completion:nil];

//モーダル遷移
 [self.window.rootViewController presentViewController:vc animated:YES completion: nil];}'''
