【问题描述】：

我是 ios 开发的新手。有任务通过 CarPlay 扩展我们的 iOS 应用程序。我创建了“CarPlaySceneDelegate”类作为 Car Play 的入口点。代码如下：

class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate 
    var interfaceController: CPInterfaceController?
    
    func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene,
                                  didConnect interfaceController: CPInterfaceController) 
        self.interfaceController = interfaceController
        ...
        interfaceController.setRootTemplate(tabBarTemplate, animated: true)
        
          

    private func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene,
          didDisconnect interfaceController: CPInterfaceController) 
          self.interfaceController = nil
    

我在 Info.plist 中添加了这个配置：

<key>UIApplicationSceneManifest</key>
    <dict>
        <key>UIApplicationSupportsMultipleScenes</key>
        <true/>
        <key>UISceneConfigurations</key>
        <dict>
            <key>UIWindowSceneSessionRoleApplication</key>
            <array>
                <dict>
                    <key>Configuration Name</key>
                    <string>Default configuration</string>
                    <key>Delegate Class Name</key>
                    <string>$(PRODUCT_MODULE_NAME).SceneDelegate</string>
                    <key>Storyboard Name</key>
                    <string>Main</string>
                </dict>
            </array>
            <key>CPTemplateApplicationSceneSessionRoleApplication</key>
            <array>
                <dict>
                    <key>UISceneClassName</key>
                    <string>CPTemplateApplicationScene</string>
                    <key>UISceneConfigurationName</key>
                    <string>BlueGate-Car</string>
                    <key>UISceneDelegateClassName</key>
                    <string>$(PRODUCT_MODULE_NAME).CarPlaySceneDelegate</string>
                </dict>
            </array>
        </dict>
    </dict>

在模拟器上启动时，CarPlay 根据 CarPlaySceneDelegate 类启动良好。但是在 iPhone Simulator 上它根本没有启动。应用加载和屏幕变黑。

在控制台中：

我的环境 Xcode 12.5.1

我做错了什么还是有什么其他方法可以通过 Xcode/swift 实现 CarPlay 部分功能，同时将移动应用程序保留在 iOS 上？

感谢任何 cmets 或帮助。

【问题讨论】：

如果我从 Info.plist 中删除 UIWindowSceneSessionRoleApplication 没有任何变化

问题出在哪里还不是很清楚。 “在模拟器上启动 CarPlay 启动良好”/“在 iPhone 模拟器上它没有启动”：您的意思是您的 CarPlay 应用程序在通过 I/O-External Displays-CarPlay 启动 CarPlay 模拟器时启动......但是您的 iOS 应用程序没有启动自从你做出改变后就不再了吗？

【参考方案1】：

你的应用场景在plist中的key好像不对。尝试使用UISceneConfigurationName 代替Configuration Name、UISceneDelegateClassName 代替Delegate Class Name 和UILaunchStoryboardName 代替Storyboard Name。
