在iPad-Storyboard中添加一个带有Navigation-Controller的empty-View-Controller 将类更改为你的第一个用于iPhone的ViewController的类"fooViewController" 为第一个ViewController添加iPhone-Storyboard "fooViewController_storyboard_identifier"中的Storyboard-Identifier 转到fooviewcontroller。m 添加bool变量bool nibWasLoadForIpad=false 进入viewDidLoad-Method

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad && !nibWasLoadForIpad) ｛ nibWasLoadForIpad = true; UIStoryboard* Storyboard_iphone=[UIStoryboard storyboardWithName:@"Main_iPhone" bundle: nil]; fooViewController *controller = [Storyboard_iphone instantiateViewControllerWithIdentifier:@"fooViewController_storyboard_identifier"]; (自我。导航控制器pushViewController:控制器动画:YES]; 自我。modalPresentationStyle = UIModalPresentationCurrentContext; ｝

(ps.知道的问题是视图背景将被设置为白色)

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……

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

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。
