Though this is an old post, I also faced this situation recently. Just implement the protocol <code>UIContentContainer</code>
<pre><code>@interface MyViewController : NSObject &lt;UIContentContainer&gt;
</code></pre>
And implement the method in the implementation and within the method add call your function.
<pre><code>@implementation MyViewController {
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id&lt;UIViewControllerTransitionCoordinator&gt;)coordinator {
 [self onChangeStatusBarOrientationNotification];
 }
@end
</code></pre>
<h2>Swift</h2>
<pre class="lang-swift prettyprint-override"><code>override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
 super.viewWillTransition(to: size, with: coordinator)
 
 // Put code to be run BEFORE the rotation here... 

 coordinator.animate(alongsideTransition: nil) { _ in
 // Put code to be run after the rotation,
 // or after frame-size change here...
 }
}
</code></pre>
Some other useful checks:
<pre><code>if UIDevice.current.orientation.isLandscape {
 print(&quot;Landscape&quot;)
}
if UIDevice.current.orientation.isFlat {
 print(&quot;Flat&quot;)
} else {
 print(&quot;Portrait&quot;)
}
</code></pre>

blocks|key|4070383|text|试一试如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4070384|[[NSNotificationCenter+defaultCenter]+addObserver:+self
++++selector:+@selector(onChangeStatusBarOrientationNotification:)

Try something like:
<pre class="lang-objectivec prettyprint-override"><code>[[NSNotificationCenter defaultCenter] addObserver: self
 selector: @selector(onChangeStatusBarOrientationNotification:)
 name: UIDeviceOrientationDidChangeNotification
 object: nil];
</code></pre>
But note that it just works and I never call below:
<pre class="lang-objectivec prettyprint-override"><code>[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
</code></pre>
So, maybe it's enabled by default.
<h2>Swift 5</h2>
<pre class="lang-swift prettyprint-override"><code>NotificationCenter.default.addObserver(self,
 selector: #selector(onLayoutChange),
 name: UIDevice.orientationDidChangeNotification,
 object: nil)

// ...

@objc public func onLayoutChange() {
 // Handle change here.
}
</code></pre>

I have the same problem, and here is what worked for me:
In my UIViewController I had to override the viewWillTransition function and voila.
<pre><code>override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
 super.viewWillTransition(to:size, with: coordinator)
 let before = self.view.window?.windowScene?.interfaceOrientation
 coordinator.animate(alongsideTransition: nil) { _ in
 let after = self.view.window?.windowScene?.interfaceOrientation
 if before != after {
 // rotation detected, call you rotation handler here
 }
 }
</code></pre>
}

Mahmud Ahsan's answer is good just that is missing the detection code.

I have changed my app target to IOS 13 to check the deprecated methods in my app and I am getting below warning: 

<blockquote>
 'UIApplicationDidChangeStatusBarOrientationNotification' is deprecated: first deprecated in iOS 13.0 - Use viewWillTransitionToSize:withTransitionCoordinator: instead. 
 Here is the code which I have implemented in my project. 
</blockquote>

<pre><code> - (instancetype)init
{
 self = [super init];
 if (self) {
 [[NSNotificationCenter defaultCenter] addObserver:self
 selector:@selector(onChangeStatusBarOrientationNotification:)
 name:UIApplicationDidChangeStatusBarOrientationNotification
 object:nil];
 }
 return self;
}
</code></pre>

Please suggest me the solution for ios 12 and ios 13.

Thanks in advance.

UIApplicationDidChangeStatusBarOrientationNotification is deprecated, any alternative?
