I solved this with different approach.

Don't make subclass of UIImagePickerController because Apple does not support subclass of UIImagePickerController.

Important

<blockquote>
 The UIImagePickerController class supports portrait mode only. This
 class is intended to be used as-is and does not support subclassing.
 The view hierarchy for this class is private and must not be modified,
 with one exception. You can assign a custom view to the
 cameraOverlayView property and use that view to present additional
 information or manage the interactions between the camera interface
 and your code.
</blockquote>

Here is alternate solution:

Add this code in UIViewController

<blockquote>
<pre><code>self.imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imagePickerController.showsCameraControls = NO;
self.imagePickerController.delegate = self;

[self.view addSubview:self.imagePickerController.view];
[self addChildViewController:self.imagePickerController];
[self.imagePickerController didMoveToParentViewController:self];
</code></pre>
</blockquote>

Working Fine in all iOS version and devices. :):)

Use <code>UIImagePickerController()</code> instead of any other initializer.

I am facing the same problem, and it is caused by calling the wrong initializer.

You need to add privacy setting for camera to info.plist to access camera if you are using Xcode 8

Possible reasons could be one of below listed, try and check if it help:

------ Try Code related to show <code>UIImagePickerController</code> in Main thread:

<pre><code>dispatch_async(dispatch_get_current_queue(), ^(void){

 //Code related to show UIImagePickerController

 .....

 self.imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
 self.imagePickerController.showsCameraControls = NO;
 self.imagePickerController.delegate = self;

 [self.view addSubview:self.imagePickerController.view];
 [self addChildViewController:self.imagePickerController];
 [self.imagePickerController didMoveToParentViewController:self];

 .....

});
</code></pre>

----- Check info.plist >Bundle display name:

If info.plist >Bundle display name is blank then add Bundle display name key with value your application name.

------ Set privacy setting for camera to <code>info.plist</code> for accessing camera:

Camera :

Key : <code>Privacy - Camera Usage Description</code> 
Value : <code>$(PRODUCT_NAME) camera use</code>

------ Don't subclass <code>UIImagePickerController</code>:(as Ankit Gupta's answer suggest)

<blockquote>
 The UIImagePickerController class supports portrait mode only. This
 class is intended to be used as-is and does not support subclassing.
</blockquote>

Assign a custom view to the <code>cameraOverlayView</code> property and use that view to present additional information or manage the interactions between the camera interface and your code.

blocks|key|2964505|text|也许你忘了展示UIImagePickerController，这就是为什么你要得到空白屏幕的原因:-|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2964506|[self+presentViewController:yourImagePickerController+animated:YES+completion:NULL];|code-block|syntax|javascript|2964507|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Maybe you forgot to present the UIImagePickerController that's why you're getting the blank screen :-

<pre><code>[self presentViewController:yourImagePickerController animated:YES completion:NULL];
</code></pre>

blocks|key|2964590|text|你是用UIActionSheet来显示UIImagePickerController的吗？我用UIAlertController代替UIAlertController解决了这个问题。因为UIAlertView可能会导致bugs.DO不再使用UIAlertView；)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2964591|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|$]]

are you using UIActionSheet to show UIImagePickerController? I solved it by replace UIActionSheet by UIAlertController. Because UIAlertView may will cause unhappend bugs.DO NOT USE UIAlertView anymore;)

blocks|key|2964519|text|我也面临着同样的问题。关于iOS10的一些奇怪的事情。所以我想出了解决办法。即使您正在使用UIImagePickerController或用您的viewController扩展它。只需创建UIImagePickerController的一个实例，并以viewDidLoad表示它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2964520|UIImagePickerController+*imagePickerController+=+UIImagePickerController+alloc;|offset|length|style|BOLD|2964521|自表示视图控制器:imagePickerController动画:是完成:零；|2964522|entityMap^0|0|0|27|0|0|13|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@$D|Q|E|R|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|K|$]]

I was facing the same issue. Something weird with iOS10. So here i came up with the solution. Even though you are using UIImagePickerController or extending it with your viewController. Just Make an instance of UIImagePickerController and present it in viewDidLoad. 

UIImagePickerController *imagePickerController = [UIImagePickerController alloc];

[self presentViewController:imagePickerController animated:YES completion:nil];

I'm facing a strange problem.... 
On devices running <code>iOS 10</code> camera preview shows black screen. 
But in older version it works fine. 
I'm using <code>UIImagePickerController</code> with 

<pre><code>self.sourceType = UIImagePickerControllerSourceTypeCamera;
</code></pre>

My info.plist file:
