从LaunchScreen看到Main.Storyboard中的viewController？ [英] Segue from LaunchScreen to a viewController in Main.Storyboard?

问题描述

我在LaunchScreen中有一些我想要做的逻辑，如果检查没问题，我想要转到viewController，如果不是，我想要转向另一个，这可能吗？

I got some logic I want to do in my LaunchScreen, and if the check is alright, I want to segue to a viewController and if not I want to segue to another, is that possible?

推荐答案

我在LaunchScreen中想要做一些逻辑

I got some logic I want to do in my LaunchScreen

现在我理解了这个问题，我可以回答：不要。稍后做你耗时的逻辑。您的工作是快速启动 。您需要退出 applicationDidFinishLaunchingWithOptions ，退出 viewDidLoad ，然后启动。

Now that I understand the question, I can answer it: don't. Do your time-consuming logic later. Your job is to launch fast. You need to get out of applicationDidFinishLaunchingWithOptions, get out of viewDidLoad, and launch.

你在那一点展示的是由你决定的;如果你有耗时的东西（在你的情况下，这听起来像你正在联网或做一些其他的东西需要时间，你加载一个表的数据源），你想要显示一个特殊的视图控制器，涵盖时间有旋转活动视图或其他东西，很好。但在实际发布期间不是时候做到这一点。

What you show at that point is up to you; if you have time-consuming stuff (in your case, it sounds like you're networking or doing something else that takes time while you load up the data source for a table) and you want to show a special view controller that covers the time with a spinning activity view or something, fine. But during actual launch is not the time to do that.
