You can't. You can only set the orientation for user interface when the iPhone App launches. In addition, you can change the orientation of your device:

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

and provide the appropriate response to shouldAutorotateToInterfaceOrientation:

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