就图标而言，Capacitor是所有构建目标中最复杂的目标之一，因为不仅需要将图标放置在特定的文件夹中，而且还需要在两个平台（Android，iOS）的配置文件中注册图标 。
如果您发现一个新的或丢失的文件，请打开问题。
Icon Genie CLI
TIP
我们强烈建议您使用Icon Genie CLI，因为它使用一个源图标并自动克隆、缩放、缩小图标并将其放置在适当的目录中。当需要时，它还会告诉您需要向/src/index.template.html文件添加哪些标记。
使用Icon Genie CLI快速启动必要的图像。有关选项的完整列表，请访问Icon Genie CLI命令列表页面。
$ icongenie generate -m capacitor -i /path/to/source/icon.png [-b /path/to/background.png]
根据您将要使用的packager（electron-packager或electron-builder），请参阅他们的文件如何钩住图标。
手动指引
除非您使用的是Icon Genie CLI，否则这是您需要做的：
$ cd src-cordova
$ cordova plugin add cordova-plugin-splashscreen
$ cordova plugin save
