I've looked at several answers to questions similar but none of the answer worked. I have an app where I need everything portait except for one photo viewer I have. In the supported orientations section of the targets menu I only have portrait. How do I force my one view to be landscape. It is being pushed onto the stack from a nav controller but I'm using storyboards to control all that.

Since the answer seems to be hidden in the comments of the question and since ArunMak's answer is quite confusing, I'll just offer what I found out:

All I had to do was to add this function to my custom UIViewController subclass for the view:

- (NSUInteger)supportedInterfaceOrientations {
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        // iPad: Allow all orientations
        return UIInterfaceOrientationMaskAll;
    } else {
        // iPhone: Allow only landscape
        return UIInterfaceOrientationMaskLandscape;
    }
}

Note that the project needs to allow all orientations (that is: Portrait, Landscape Left, Landscape Right - but NEVER Upside Down on an iPhone!).

If you want to limit some or most views to Portrait, you need to implement the above method in every of those view controllers (or use a common super class for it and subclass all others from it) — if you limit the Device Orientation in the Info.plist to just Portrait, the app will never even think of going into landscape.
