当设备旋转iPhone / iPad时，也会使子视图旋转 [英] Make subview rotate too when device is rotated iPhone/iPad

问题描述

当我说我想要旋转我的子视图时，让我解释一下我的意思。我放了很多图像让我自己清楚。这可能看起来很多，但事实并非如此。只是想清楚。

Let me explain what I mean when I say that I want to rotate my subview too. I placed a lot of images to make my self clear. This may look like to much but it is not. Just wanted to be clear.

在我目前正在处理的nib文件中，我有一个UIView和按钮。

In the nib file that I am currently working on, I have a UIView and button.

我在界面中创建的UIView builder与名为ViewMain的IBOutlet相关联：

The UIView that I created in interface builder is connected with the IBOutlet named ViewMain:

按钮执行以下方法：

and the button executes the following method:

该方法的作用是将视图放置在我在界面中创建的UIView控制器中的另一个nib文件中建设者。我实际放置的nib文件是：

and what that method does is that it places the view from another nib file in the UIView controller that I created in interface builder. The nib file that I am actually placing is:

我只是放置随机控件以更好地说明我的观点。

I just placed random controls to illustrate better my point.

所以到目前为止一切都很棒（当用户按下按钮时，来自另一个ViewController的视图出现在ViewMain上）

so everything so far is great (the view from anotherViewController shows up on ViewMain when the user presses the button)

一切看起来很棒但是注意什么时候发生什么我旋转我的设备：

EVERYTHING LOOKS GREAT BUT NOTE WHAT HAPPENS WHEN I ROTATE MY DEVICE:

我希望我的子视图（anotherViewController.view）也可以进行评估。我不介意它是否比ViewMain更大，因为我可以有一个透明的背景。我只需要旋转它。我怎么能这样做？

I would like my subview (anotherViewController.view) to ratate as well. I don't mind if it is bigger than ViewMain because I can have a transparent background. I just need to rotate it as well. How can I do that?

推荐答案

定义 shouldAutorotateToInterfaceOrientation：在你 UIViewController 这样它总是返回YES：

Define shouldAutorotateToInterfaceOrientation: in you UIViewController so that it always returns YES:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
 {
    return YES;
 }

看这里了解更多详情。

您还应该注意正确定义视图和子视图的自动调整行为，以便在自动旋转时一切正常。

You should also take care to correctly define the autoresizing behavior of your view and subviews, so that everything is fine when autorotating.

编辑：

在Interface Builder中设置视图的autoresize属性，选择视图，然后转到Info窗口中的View Size窗格并设置自动调整如下图所示。

to set the autoresize property for a view in Interface Builder, select the view then go to the "View Size" pane in the Info window and set "Autosizing" as in the image below.
