objective-c - 如何在 iOS 中创建不使用图像的动画启动画面

Question

我想知道应该如何构建动画启动画面。我已经用图像制作了动画启动画面，但在这里我想添加自定义动画，比如在屏幕上绘制的东西等。谁能指导我完成这个。

简单地说，您需要呈现一个 UIViewController，它会保留您的动画并在您的应用准备好启动时关闭它。但我也认为跟随苹果更好HIG ..正如苹果描述的那样

Supply a launch image to improve user experience.

Avoid using your launch image as an opportunity to provide:

An “application entry experience,” such as a splash screen An About window Branding elements, unless they are a static part of your application’s first screen Because users are likely to switch among applications frequently, you should make every effort to cut launch time to a minimum, and you should design a launch image that downplays the experience rather than drawing attention to it.

Generally, design a launch image that is identical to the first screen of the application.

Exceptions:

Text. The launch image is static, so any text you display in it will not be localized.

UI elements that might change. Avoid including elements that might look different when the application finishes launching, so that users don’t experience a flash between the launch image and the first application screen.
