Unwanted UIView Autorotating: Navigation Controller Push

Question

I have a navigation controller and it goes through that in portrait. Then, at a certain point, I push to a view that displays a graph, which I want to only display in landscape, and not even be in portrait at all (this screws up how the view looks).

In this view, GraphViewController, I have the following method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

When the view first gets pushed, it appears in portrait mode. If I rotate the phone, the view will rotate into landscape also (not upside down portrait). But I want it to not even ever be in portrait mode, not even when it starts. I have verified that this method is getting called by adding a NSLog.

I saw these posts but could not get it to work. Thanks!!

Answer 1

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations.
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
