推荐答案

如果通过启动画面"表示您的应用启动时显示的图像，则答案是您不能.

If by "Splash Screen" you mean the image that is displayed when your app launches, the answer is that you can't.

您可以做的是创建一个初始视图，其中包含一个看起来与启动图像相似的背景图像，然后在该视图中添加一个活动指示器.对于用户，活动指示器似乎是启动图像的一部分".

What you can do is have an initial view that includes a background image that looks just like your launch image, and then add an activity indicator into that view. To the user, it will appear that the activity indicator is "part" of your launch image.

诀窍是尽快加载初始笔尖(使其小而简单)，以便静态图像过渡到可以立即操作的视图.

The trick is to load your initial nib as quickly as possible (keep it small and simple) so the static images transitions to a view you can manipulate right away.
