UINavigationController，错误的背面 animation 方向

Question

I have a really weird problem, driving me crazy!

My app has only one orientation: portrait. By pushing a button you can open a UINavigationController modally (by calling the method presentModalViewController ...). This UINavigationController can be orientated ( shouldAutorotate always returns YES ).

That works fine except for one thing: The transition. it is always in portrait. I don't understand why. I tried to set the status bar's orientation to match the UINavigationController's orientation but it didn't work. I m very puzzled...

Can anybody help me?

thanks!

Use this code on.m of that view controller where you r presenting modal

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{

    if((toInterfaceOrientation == UIInterfaceOrientationPortrait) ||(toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))
        return NO;

    return YES;
}
