我在Sencha Touch 2.3.1-gpl中创建了一个跨平台应用程序（将针对 iOS、Android 和 Windows Phone 打包）并通过phonegap.com (Phonegap cloud)为 iOS 打包它。该应用程序和应用程序图标在所有 iOS 设备上都可以正常工作，但是当应用程序启动时，会显示此默认的 Phonegap启动屏幕：
我在 Phonegap（云）UI 中找不到任何选项来为我的应用程序选择启动画面：
现在我的问题是：
我可以在哪里或如何为我的应用程序定义自定义启动画面？
是否必须在 Sencha Touch 应用程序代码中指定启动画面？或者是否必须将其添加到 Phonegap（云）UI 中的某处？
这是我的 Sencha Touch app.js 代码，我没有指定任何图标或启动画面，因为根据我的理解，图标和启动画面必须添加到 Phonegap（云）中：
