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

当我昨天遇到同样的问题时，我关注了这个帖子。我遵循的步骤

For Xcode 5.1, I had to do some cleanup of iPhone storyboard like missing reuseIdentifiers of Table cells, provide story board id for every controller, remove unused scenes. Copy MainStoryboard_iPhone.storyboard to MainStoryboard_iPad.storyboard. Using vi editor - changed targetRuntime="iOS.CocoaTouch" to targetRuntime="iOS.CocoaTouch.iPad" Change the code in the MainStoryboard_iPad.storyboard from: <simulatedScreenMetrics key="destination" type="retina4"/> to <simulatedScreenMetrics key="destination"/> Open the project in Xcode. Changed the Deployment devices to Universal - Chose the option of NOT copying the iPhone Storyboard. Xcode will default the Deployment Target to 7.1, took care of the deprecated functions. To fix the misplaced view error in iPad Storyboard - Changed the Frame Layout for Controllers giving errors.

就是这样。谢谢你的帮助。

谢谢大家的回答。

我遵循了上述步骤，但当我在模拟器或iPad下运行应用程序时，它只使用iPhone故事板继续运行。

由于某种原因，当我将目标设备改为Universal而不是iPhone时，Xcode (v5.0)没有更新app-Info。plist文件来包含iPad故事板，所以我必须手动添加以下条目(使用Xcode中的plist编辑器):

主故事板文件基名(iPad) ==> MainStoryboard_iPad

如果你创建了一个通用项目，默认情况下会创建空的iPad storyboard，你只需要选择iPhone storyboard select all (Command+ a)，复制(Command+C)，然后粘贴到iPad storyboard上。在编译之前，请确保将入口点从空故事板移动到新复制的故事板。

通过阅读stackoverflow上的许多线程，我发现解决方案是-

1.复制你的iPhone-Storyboard并重命名为MainStoryboard_iPad.storyboard

2.右击故事板->“打开为”->“源代码”。

3.搜索targetRuntime="iOS "。CocoaTouch，然后把它改成targetRuntime=" ios。CocoaTouch。ipad "

5.搜索<simulatedScreenMetrics key="destination" type="retina4"/>并将其更改为<simulatedScreenMetrics key="destination"/>

4.现在保存所有内容，右键单击MainStoryboard_iPad。storyboard " open as " ->"IOS storyboard " 5. 您可能还必须更改您的约束条件。 这就是你所做的一切。
