Question

What's the best way to create an iPhone application that runs in landscape mode from the start, regardless of the position of the device?

Both programmatically and using the Interface Builder.

Answer 1

See this answer: Landscape Mode ONLY for iPhone or iPad

1. add orientation to plist
2. shouldAutorotateToInterfaceOrientation = YES in all files

Although if you're using mixed modes, you might be better off with

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

Answer 2

sasb's and michaelpryor's answer appears to be correct, but if it's not working for you, try this alternative:

- (void)applicationDidFinishLaunchingUIApplication *)application {
    application.statusBarOrientation = UIInterfaceOrientationLandscapeRight;
}

Or this one:

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

Or this one:

[application setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated:NO];

You may also have to call window makeKeyAndVisible; first.
