Force iOS device to change orientation

First of all, I would like to apologize for asking the same question again that has been asked on this forum many times. But, my problem is that I tried all the proposed solutions, but still I have no solution to my problem.

I have both ViewControllerA

in Potrait mode and ViewControllerB

in landscape mode. When the device changes from cover to landscape, I see an ViewControllerB

opening in landscape mode, but when the device is rotated back to drive mode, it is displayed ViewControllerA

but still in landscape mode. Can anyone help me figure out how I can display it back in potrait mode?

I tried the following things, but nothing worked for me:

Added the following code to ViewControllerA

in viewWillAppear

:

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

Also added the following functionality in this view controller:

- (BOOL)shouldAutorotate
{
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
   return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
     return UIInterfaceOrientationPortrait;
}

Hope this helps you with supportedInterfaceOrientationsForWindow

Appdelegate.h

@property () BOOL restrictRotation;

in Appdelegate.m

  -(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    //restrictRotation is BOOL value
     if(self.restrictRotation)//set the bool value to view controller which you want to load in landscape
          return UIInterfaceOrientationMaskLandscape;
     else
       return UIInterfaceOrientationMaskAll;
}


// call this wherever you want

requiredViewController.m

-(void) restrictRotation:(BOOL) restriction
{

  appDelegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
  appDelegate.restrictRotation = restriction;
}

// In ViewdidLoad ()

- (void)viewDidLoad
 {
   [super viewDidLoad];
   [self restrictRotation:YES];//Set YES if required in Landscape mode
 }

Try



[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:@"orientation"];
0

Use below code

-(void) viewDidAppear:(BOOL)animated
{
[UIViewController attemptRotationToDeviceOrientation];
[super viewDidAppear:animated];
}

& also in viewWIllAppear write

[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:@"orientation"]
