The camera on the background still rotates, but your overlay view doesn´t.
Hope it works for you

blocks|key|1395790|text|你不需要“在纵向模式下锁定UIImagePicker控制器”。正如你所说的“当它改变为横向模式时，它看起来有些奇怪”，实际上我不知道你为什么说它看起来奇怪。但是，这是我的经验，UIImagePicker视图在景观模式下看起来很奇怪。也就是说:当AViewController作为根视图控制器时。BViewController的视图将子视图添加到AViewController的视图中。和BViewController中的presentModalViewController:UIImagePickerController。在横向模式下，UIImagePicker视图看起来会很奇怪。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1395791|这个问题的解决方案是在presentModelViewController之前将UIImagePickerController设置为根视图控制器。下面的源代码显示了详细信息：|1395792|-+(void)+onCameraButtonTapped:(UIBarButtonItem+*)buttonItem

You don't have to "lock the UIImagePicker Controller in Portrait mode".
As you said "when it is changed to landscape mode it looks some odd"
Actually I don't know why you say it look odd.
But, here is my experience of UIImagePicker view look odd in landscape mode.
That is:
When AViewController as the root view controller.
And BViewController's view add subview to AViewController's view.
And <code>presentModalViewController:UIImagePickerController</code> in BViewController.
The UIImagePicker view will look odd in landscape mode.

The solution to this problem is set the <code>UIImagePickerController</code> as the root view controller before presentModelViewController.
The source code below show the detail:

<pre><code>- (void) onCameraButtonTapped:(UIBarButtonItem *)buttonItem
{ 
 //backupRootController it's use as a backup, it will recover after close the image picker controller.
 self.backupRootController = [[UIApplication sharedApplication] keyWindow].rootViewController;

 UIImagePickerController * imageController = [[UIImagePickerController alloc] init];
 imageController.sourceType = UIImagePickerControllerSourceTypeCamera;
 imageController.delegate = self;
 ....
 [[[UIApplication sharedApplication] keyWindow] setRootViewController:imageController];
 [self presentModalViewController:imageController animated:YES];
 [imageController release];
}


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
 [[[UIApplication sharedApplication] keyWindow] setRootViewController:self.backupRootController];
 ....
}
</code></pre>

I hope this solution can help other person in the future.

blocks|key|1395802|text|对我来说唯一有效的解决方案是类别，但我还必须添加另一个方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1395803|#import+"UIImagePickerController%2BNoRotate.h"

@implementation+UIImagePickerController+(NoRotate)

-+(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

}

-+(NSUInteger)supportedInterfaceOrientations

The only solution that worked for me was the category, but I had to add another method too:

<pre><code>#import "UIImagePickerController+NoRotate.h"

@implementation UIImagePickerController (NoRotate)

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

- (NSUInteger)supportedInterfaceOrientations
{
 return UIInterfaceOrientationMaskPortrait;
}
@end

Try this in your view controller. This worked for me.
Note: This is for ios6.0 and above

blocks|key|375847|text|或者，您可以创建UIImagePickerController的子类：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|375848|创建一个新的UIImagePickerController类，并向其中添加以下行。|375849|-+(BOOL)shouldAutorotate{
return+NO;
}|code-block|syntax|javascript|375850|将其导入使用摄影机的类，并使用您创建的类，而不是使用默认的UIImagePickerController。|375851|你的相机本身应该停止自动旋转。|375852|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Or, you can subclass the UIImagePickerController:

Create a new UIImagePickerController class and just add these lines to it.

<pre><code>- (BOOL)shouldAutorotate{
return NO;
}
</code></pre>

Import it to the class that uses the camera and instead of using default UIImagePickerController, use the class that you created.

Your camera itself should stop from auto rotating.

blocks|key|286074|text|不需要创建子类，只需为uiimagepickercontroller创建一个类别并将以下行放入其中-+(BOOL)shouldAutorotate{+return+NO；}|type|unstyled|depth|inlineStyleRanges|entityRanges|data|286075|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

there is no need to create a subclass, just create a category for uiimagepickercontroller and put this line on it
- (BOOL)shouldAutorotate{
return NO;
}

In my IOS app, when I open the camera I have placed an image over the camera view. It looks good in portrait mode. But when it is changed to landscape mode it looks some odd. So I want to lock the <code>UIImagePickerController</code> in Portrait mode.

Following is my code for ui image picker controller

<pre><code>UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
imgPkr.delegate = self;
imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
</code></pre>

How it can be locked in portrait mode....
