如何更改应用启动时加载的默认视图控制器? [英] How to change the default View Controller that is loaded when app launches?

问题描述

我有一个应用程序，比如说MyApp"，它在应用程序启动时默认加载视图控制器MyAppViewController".后来，我在项目中添加了一个新的视图控制器NewViewControler".

I have an application, say 'MyApp', which by default loads the view controller 'MyAppViewController' whenever the application launches. Later, I added a new view controller 'NewViewControler' to the project.

我现在希望NewViewController"成为我的默认视图控制器，在应用程序启动时加载.

I now want the 'NewViewController' to be my default view controller which loads when the app launches.

请让我知道我需要在我的项目中进行哪些更改才能实现这一目标.

Please let me know what changes I need to make in my project to achieve this.
