Question

When running the app on iOS 6, my app no longer successfully autorotates. I have updated to Cordova 2.1, and I have the following code in my MainViewController.m file (which is a subclass of CDViewController, to be compatible with the new iOS6 way of handling autorotation:

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

// iOS 6
- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    NSUInteger ret = 0;

    if ([self shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationPortrait])
        ret = ret | (1 << UIInterfaceOrientationPortrait);
    if ([self shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationPortraitUpsideDown])
        ret = ret | (1 << UIInterfaceOrientationPortraitUpsideDown);
    if ([self shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight])
        ret = ret | (1 << UIInterfaceOrientationLandscapeRight);
    if ([self shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeLeft])
        ret = ret | (1 << UIInterfaceOrientationLandscapeLeft);

    return ret;
}

In your AppDelegate.m you need to add the following to didFinishLaunchingWithOptions

[self.window setRootViewController:self.viewController];

Once you add this, rotation should start working again. It has for my two apps.
