Device orientation is not changing in iOS?

Question

I'm using an iPAD 2 with OS version 9.3. My application tries to change the device orientation but its not changing. How to change device orientation in iOS 9.0. My question is when app is started it should be Portrait and should not autorotate. After button click it should change orientation to LandscapeRight.

And for your info all orientations are checked in project .plist file

My code in my view controller:

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];    
    [[UIDevice currentDevice] setValue:
     [NSNumber numberWithInteger: UIInterfaceOrientationPortrait]
                                forKey:@"orientation"];   
}

- (BOOL)shouldAutorotate {
    return NO;
}

and on a button click

-(IBAction)playMyVideo:(MPMediaItem*)item{        
    [[UIDevice currentDevice] setValue:
     [NSNumber numberWithInteger: UIInterfaceOrientationLandscapeRight]
                                forKey:@"orientation"];
}

What is the problem with the code? If there isn't any problem what is the solution for this?

Note: In iPhone there is an app called Videos he is handling the rotation on button clicks. Its a system app. How is he doing that.

are you want to display view controller on portrait mode only — Bhupat Bheda, Apr 25 '17 at 12:32
Read the question carefully guys. @KKRocks and Bupat Bheda. All orientations are checked. — AMI amitekh, Apr 25 '17 at 12:34

-(NSUInteger)supportedInterfaceOrientations { } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskLandscape; } -(BOOL)shouldAutorotateToInterfaceOrientation: } // add these — Ajjjjjjjj, Apr 25 '17 at 13:37
@TejaNandamuri That will auto rotate eveyway. I dont want that. I want rotation on button clicks. But autorotation should be shut. — AMI amitekh, Apr 25 '17 at 13:57
@ajjjjjjjj Please understand I don't want auto rotation. I want rotation on button clicks. And please give an answer . — AMI amitekh, Apr 25 '17 at 14:09
There is no officially documented way to do what you are asking for. There are several workarounds posted under this question: http://stackoverflow.com/questions/181780/is-there-a-documented-way-to-set-the-iphone-orientation - but most of them are kludges and will probably break in future versions of iOS (if they haven't already), or will get your app rejected on app store submission. Apple doesn't want you setting the orientation manually because they feel it will confuse users and it breaks their UI design guidelines. — Jeff Loughlin, Apr 25 '17 at 14:10
there is One way, use 2 viewcontroller objects... one with portrait and other landscape Orientation. this will work Smooth — Ajjjjjjjj, Apr 26 '17 at 07:53
