How to override supportedInterfaceOrientations

My code for Portrait/UpsideDown orientation in Xcode 7.0.1 Obj-C is:


- (UIInterfaceOrientationMask)supportedInterfaceOrientations {

return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);

}



SLComposeViewController does not override supportedInterfaceOrientations and so it inherits the default implementation from UIViewController which returns UIInterfaceOrientationMaskAllButUpsideDown on iPhone



So I created a subclass of SLComposeViewController, but now how do I override supportedInterfaceOrientations?
