禁用UIView的自动旋转 [英] Disabling auto rotation for a UIView

问题描述

我的应用程序由后台UIView中的工具栏和AVCaptureVideoPreviewLayer组成。
我想看到工具栏按设备方向旋转，所以在我的主ViewController中，我实现了这个功能：

My application is composed of a toolbar and an AVCaptureVideoPreviewLayer in a background UIView. I'd like to see that toolbar rotate regarding the device orientation, so in my main ViewController, I implemented the function :

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait
            || interfaceOrientation == UIInterfaceOrientationLandscapeLeft
            || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

这样可以正常工作，但是当界面方向改变时，我看到了背景UIView（带有视频图层）也在旋转，所以我的视频视图现在向左或向右播放90度......这真的很酷！

所以我的问题是：有什么方法可以禁用特定UIView上的自动旋转动画？

This works fine, but when the interface orientation is changed, I see that the background UIView (with a video layer) is also rotating, so my video view is now playing 90 degrees left or right... Which is not really cool !
So my question is : is there any way to disable the auto-rotation animation on a specific UIView ?

我看到过一个类似的问题：禁用单个UIView的自动旋转，但答案不适合我的问题，我真的需要背景视图不要移动，不要用一种计数器动画解决问题。所以我决定提出这个话题。

I have seen one similar question to this one : Disabling autorotate for a single UIView, but the answers doesn't fit my problem, I really need the background view to do not move, not to get around the problem with a kind of "counter animation". So I decided to bring up this topic.

任何想法？

谢谢！

推荐答案

试试这个：

myVideoCaptureLayer.orientationSupported = NO;
