How to restrict my app to landscape mode?

Question

I have my iPad application created using the SplitView template. I wonder what is the best way to restrict my application to landscape mode?

I have tried overriding

Answer 1

I believe this is a BUG, I faced this problem also. It is something to do with

UIInterfaceOrientationLandscapeLeft

To replicate this situation:

1) Create a new iPad project using UISplitViewController template

2) Edit info.plist

Supported interface orientations
-Landscape (left home button)
-Landscape (right home button)

3) DetailViewController.m

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
//    return YES;
 NSLog(@"RotateToInterface:[%d] vs LandscapeLeft[%d]", interfaceOrientation, UIInterfaceOrientationLandscapeLeft);
 return interfaceOrientation == UIInterfaceOrientationLandscapeLeft;
}

4) Run it....You will see a blank black view. and no matter how you turn. "UIInterfaceOrientationLandscapeLeft" never detected.

By the way, nacho4d's adding BOOL check work-around is working. Thumbs UP :)
