有没有办法以编程方式编码LaunchScreen [英] Is there any way to code the LaunchScreen programmatically

问题描述

我正在使用Xcode7和Swift与Storyboard。当我打开LaunchScreen.storyboard，并尝试在其上设置自定义类时，Xcode抱怨在LaunchScreen故事板上不能有自定义类。
所以我的问题是，有没有办法以编程方式对LaunchScreen进行编码，因为我希望避免使用IB拖放元素。

I am using Xcode7 and Swift with Storyboards. When I open the LaunchScreen.storyboard, and I try to set a Custom Class on it, Xcode complains that one cannot have a custom class on a LaunchScreen storyboard. So my question is, is there any way to programmatically code the LaunchScreen as I would like to avoid having to drag and drop elements on it using IB.

推荐答案

不，在您的应用程序开始执行之前，会显示启动屏幕，以便在加载时提供从Springboard到应用程序的转换。

No, The launch screen is shown before your app starts executing in order to provide a transition from the Springboard to your app while it is loading.

您可以使用固定图像，也可以仅使用标准的静态UI元素使用简单的故事板场景 - 标签&图片。

You can either use a fixed image or you can use a simple storyboard scene using only standard, static UI elements - labels & images.

这个故事板场景实际上是由操作系统加载和显示的，因此允许代码在该上下文中执行会带来安全风险。

This storyboard scene is actually loaded and displayed by the OS, so it would be a security risk to allow your code to execute in that context.
