Landscape Mode ONLY for iPhone or iPad

I’m making an iPad-only app that I want to be landscape only throughout the entire thing.

I’m very new to iOS programming and am using the StoryBoard method of creating the interface.

When I first set up the app, I selected a single view and click the buttons to make it be landscape only. I found out that only makes it start in landscape orientation but doesn’t prevent the user from manually rotating.

So, I found I had to do:

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
        if (interfaceOrientation == UIDeviceOrientationLandscapeLeft ||  interfaceOrientation ==  UIDeviceOrientationLandscapeRight) 
        {
           return YES;
        }
        return NO;
    }

in order to prevent the user from manually rotating it.

Now, I’ve created a Navigation Controller and a regular View that I set as the Root View Controller. I’ve also added a single button inside that view.

My problem is that my app seems to be landscape only at first startup (literally flashes landscape) but then is portrait only in what seems that navigation controller.

I’ve also found selected “Orientation: Landscape” for both the Navigation Controller and that first View Controller inside the Storyboard interface.

Even when I rotate the device to landscape, the app doesn’t rotate. It seems to be stuck in portrait even though all the settings are for landscape-only.

How can I make my app landscape-only instead of its current state of portrait-only?

EDIT: I actually found my own solution.

It appears as though my view that was linked to my Navigation Controller was not linked to the class file where I was setting the code for landscape only.

All I did was select the View Controller in the Storyboard interface, click the “Show Identity Inspector” button on the right sidebar and set the class as the name of my ViewController files where the code:

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

was.

In short, my view controller wasn’t linked to the view controller class file.

Returning YES and NO is not very recommended.

Returning UIDeviceOrientationLandscapeLeft however should make your app “landscape only”:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

If that don’t work, navigate to your Info.plist

and add a Supported interface orientations row with Landscape (left home button) and Landscape (right home button).

Additionally, I recommend to change the view(s) Orientation to Landscape in the
Attributes Inspector.
