How to show scene in landscape mode within xcode storyboard?
提问by jcamacho
I have storyboard project in xcode. Most scene is show in portrait orientation but I want to show one of scene in landscape mode without user rotate the device, always this scene is shown it must be in landscape. This scene has a simple viewcontroller with uiwebview object wich I open a pdf file from url. My idea is show the viewcontroller as a modal viewcontroller.
我在 xcode 中有故事板项目。大多数场景都以纵向显示，但我想在没有用户旋转设备的情况下以横向模式显示其中一个场景，始终显示此场景必须以横向方式显示。这个场景有一个带有 uiwebview 对象的简单视图控制器，我从 url 打开了一个 pdf 文件。我的想法是将视图控制器显示为模态视图控制器。
Anyone known how solve this issue?, yesterday I spend my time searching about this in Internet but I don't find out a solution.
有人知道如何解决这个问题吗？，昨天我花时间在互联网上搜索这个问题，但我没有找到解决方案。
Thank you in advance!

How the scene is actually displayed is not determined by the storyboard but rather the viewcontroller. You need to create an UIViewControllersubclass and implement - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientationto return YESonly if the interface orientation is a landscape orientation. You could do it like this:
场景的实际显示方式不是由情节提要决定的，而是由视图控制器决定的。您需要创建一个UIViewController子类并实现仅当界面方向为横向时才- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation返回YES。你可以这样做：
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
to allow both orientations or replace with
允许两个方向或替换为
return interfaceOrientation == UIInterfaceOrientationLandscapeLeft
to allow only one direction.
只允许一个方向。
