问题描述
我得到的错误如下。
Thread 1: "Unsupported object <CP@R_490_4045@ionTemplate: 0x6000012de010> <identifier: 3444D3F1-ECFF-4953-B543-459286E11371,userInfo: (null),tabTitle: (null),tabImage: (null),showsTabBadge: 0> passed to setRoottemplate:animated:completion:. Allowed classes: {(\n CPTabBarTemplate,\n CPListTemplate,\n CPGridTemplate,\n CPAlertTemplate,\n CPVoiceControlTemplate,\n CPNowPlayingTemplate\n)}"
我所做的只是显示一个简单的基本文本。 - 我正在关注https://adapptor.com.au/blog/enhance-existing-apps-with-carplay
任何建议都会有所帮助。

解决方法
您在项目中定义了哪些权利？模板的可用性取决于定义的应用权利。
使用不受支持的模板 (CPInformationTemplate) 会导致您的错误。
例如来自documentation：
您不能在带有音频的应用中使用 CPInformationTemplate 权利。
