如何从 iOS 游乐场中的文件实例化 Storyboard? [英] How do you instantiate a Storyboard from a file within an iOS playground?

问题描述

假设您已将 Main.storyboard 从 Xcode 6 项目复制到独立 Playground 的 Resources 目录中.如何使用 Main.storyboard 文件实例化 UIStoryboard?尝试通过 nil 使用默认值不起作用:

Let's assume you've copied a Main.storyboard from an Xcode 6 project into a standalone playground's Resources directory. How can you instantiate a UIStoryboard using the Main.storyboard file? Trying to use the default via nil doesn't work:

let storyboard = UIStoryboard(name: "Main", bundle: nil)

也没有明确使用主包:

let storyboard = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())

即使 Playground 是情节提要的 Xcode 项目的一部分，我也会收到同样的错误:在捆绑 NSBundle 中找不到名为‘main’的情节提要..."

Even if the playground is part of the storyboard's Xcode project, I receive the same error: "Could not find a storyboard named 'main' in bundle NSBundle..."

似乎捆绑路径是正确的，应该能够反序列化故事板文件.

Seems that the bundle path is correct and should be able to deserialize the storyboard file.

推荐答案

我发现了这个:

你可以将一个xib文件扔到你的资源中，但是playground无法读取或运行它，因为它不是编译形式.今天，我(终于！)想到使用ibtool来预编译我的MainMenu.xib文件进入 nib 然后加载它.当你安装 Xcode 的命令行工具时，ibtool 被添加到/usr/bin.所以你需要做的就是编译你的 nib 是发出以下命令:

"You can throw a xib file into your Resources, but the playground cannot read it or run it because it’s not in compiled form. Today, I (finallly!) thought of using ibtool to pre-compile my MainMenu.xib file into nib and then load that. When you install Xcode’s command line tools, ibtool gets added to /usr/bin. So all you need to do to compile your nib is issue the following command:

ibtool --compile MainMenu.nib MainMenu.xib`

将生成的笔尖放入您的 Playground 的资源文件夹中，您就可以加载它了."

Throw that resulting nib into your playground’s resources folder and you’re ready to load it up."

您的故事板将被编译成多个笔尖(每个场景一个)

Your storyboard will be compiled into multiple nibs (one per scene)
