Question

I have an application with 3 tabs in TabBarController. On the first tab, it’s possible enable rotation from portrait to landscape just when the user press a button on NavigationBar? The first time the user can not rotate, only when he presses a button.

I’m using SDK iOS 6.

Thanks in advance!

Answer 1

-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    // Return YES for supported orientations
    return allowedToRotate;

}

Then just have a BOOL allowedToRotate; in your class header and set it to YES when you want to allow rotating. If you are on iOS 6:

-(NSUInteger)supportedInterfaceOrientations {

    if (allowedToRotate)
        return UIInterfaceOrientationMaskAll;
    else
        return UIInterfaceOrientationMaskPortrait;

}

That should work, though I haven’t tried it…
