Portrait orientation only for iPad?

Question

According to apple my application has to be able to run in both portrait modes. How do I accomplish this with shouldAutorotateToInterfaceOrientation??

Answer 1

Just return YES no matter what the interface orientation is. This will allow the system autorotate to the upside-down orientation.

If you don't want to support the landscape orientations, then return:

return UIInterfaceOrientationIsPortrait(interfaceOrientation);

Answer 2

This code allows any orientation except landscape:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    return (orientation != UIDeviceOrientationLandscapeLeft) &&
           (orientation != UIDeviceOrientationLandscapeRight);
}

Answer 3

Thanks for your answer 'progrmr'.
At this time iPad 3.2 coding should use interfaceOrientation instead of just orientation.
