There is a really simple solution for Xcode versions that support size classes (Tested in Xcode 7 which is the current version at the time of writing). Check the "use size classes" checkbox on a storyboard file (File Inspector), confirm that dialog that appears. Then uncheck that same checkbox - Xcode will ask you if you want to use this storyboard with an iPhone or iPad, and convert the screens in it appropriately. No need to directly edit the storyboard file. For both iPad and iPhone, just copy the same storyboard and configure one for iPad and one for iPhone using the described method.

在有人建议使用大小类之前——虽然很好，但对于重度定制的UI，比如游戏等，它们不太方便

1. Create New Storyboard file with MainStoryboard_iPad.storyboard
2. Copy All the views from MainStoryboard and paste to MainStoryboard_iPad.storyboard

你应该在苹果公司创建一个错误报告。你可以说它是我的(10167030)的副本，它自2011年9月以来一直开放。从我的角度来看，令人沮丧的事情是Xcode 3中就有这个功能……

1 -创建“MainStoryboard_iPad.storyboard”;

2 -右键单击“MainStoryboard_iPhone.”故事板”和“打开作为->源代码”。所有复印件;

3-右键单击“MainStoryboard_iPad”。故事板”和“打开作为->源代码”。粘贴了一切。现在搜索和改变:

targetRuntime = " iOS。CocoaTouch" to targetRuntime="iOS.CocoaTouch.iPad" type = " com.apple.InterfaceBuilder3.CocoaTouch.Storyboard。" to type="com.apple.InterfaceBuilder3.CocoaTouch.Storyboard.iPad.XIB"

4 -保存。现在重新打开，但是使用接口构建器。你只需要重新安排。

此方法也可用于.xib文件

这对我不太管用。我做了一些不同的事情。

为iPad版本创建一个新的故事板文件 在textwrangler(文本编辑器)中打开新文件和我想复制的文件 在这些xml标记之间将xml文本从旧文件复制到新文件 第一个标签<scenes> <!——内容视图控制器——> 粘贴在这里 结束标签</class> </classes> .结束标签

这对我很管用。我得到了一个新的布局，所有的插座都连接在一起，这为我节省了几个小时。
