how to lock portrait orientation for only main view using swift

Question

I have created an application for iPhone, using swift, that is composed from many views embedded in a navigation controller. I would like to lock the main v

Answer 1

In the main controller where you want portrait,

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

self.orientation = UIInterfaceOrientationMaskPortrait;
//Or self.orientation = UIInterfaceOrientationPortraitUpsideDown
}

and in subVC where you want Landscape use

  self.orientation =  UIInterfaceOrientationLandscapeLeft:
   self.orientation =  UIInterfaceOrientationLandscapeRight:

or you can override this method

- (NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskPortrait;
} 

This is how i would do it with Obj-c in iOS7, i think this code would work in iOS8 too
