启动屏幕不是启动屏幕.实际上，它只是一张图片，隐藏了用户召唤您的应用程序的时间与您的应用程序运行的时间之间的差距.您无法在启动屏幕上执行任何操作，因为根据定义，如果启动屏幕可见，则您的应用尚未运行.

The launch screen is not a splash screen. It is, in effect, just a picture, hiding the gap between the time the user summons your app and the time your app runs. You cannot do anything in the launch screen because, by definition, if the launch screen is visible your app is not yet running.
