启动画面的人机界面指南 是:不要使用启动画面.第二条规则是:不要使用闪屏！:
The first rule of Human Interface Guidelines for Splash Screens is: don't use splash screens. The second rule is: don't use splash screens!:
提供启动图像以改善用户体验.
Supply a launch image to improve user experience.
避免使用您的发布图片作为提供的机会:
Avoid using your launch image as an opportunity to provide:
应用程序入口体验"，例如启动屏幕
An "application entry experience," such as a splash screen
关于窗口
品牌元素，除非它们是应用程序首屏的静态部分
Branding elements, unless they are a static part of your application’s first screen
如果你绝对必须包含一个长时间的启动画面，并且有充分的理由这样做，通常的方法是抛出一个 UIImageView 包含你启动图像的副本，例如, application:didFinishLaunchingWithOptions: - 应该提供一个冗长的启动画面的错觉.
If you absolutely must include a long-duration splash screen, and have darn good reasons for doing so, the usual approach is to throw up a UIImageView containing a copy of you launch image in, e.g., application:didFinishLaunchingWithOptions: - which should provide the illusion of a lengthy splash screen.
但请不要.
