Change app extension screen rotation in lens c

You have a choice:

1- Set landscape and portrait as supported interface orientation in the project, and then for each ViewController you will override the supported interface orientation;

2- Set only portrait mode in project and in ViewController you need it, you can rotate 90 degrees

self.view.transform = CGAffineTransformMakeRotation(M_PI_2);

      

        
        
        
      

    

EDIT: you can do this. Set the controller as an observer for keyPath UIDeviceOrientationDidChangeNotification

. Then:

-(void)changedOrientation: (NSNotification *)note
{
    if (note)
    {
        UIDevice *dev = (UIDevice *)note.object;
        if ([dev orientation] == UIInterfaceOrientationLandscapeRight)
        {
            self.view.transform = CGAffineTransformMakeRotation(M_PI_2);
        }
        else if ([dev orientation] == UIInterfaceOrientationPortrait)
        {
            self.view.transform = CGAffineTransformIdentity;
        }
        else if ([dev orientation] == UIInterfaceOrientationPortraitUpsideDown)
        {
            self.view.transform = CGAffineTransformIdentity;
        }
        else if ([dev orientation] == UIInterfaceOrientationLandscapeLeft)
        {
            self.view.transform = CGAffineTransformMakeRotation(-M_PI_2);
        }
    }
}
