iphone - Storyboards orientation support for xCode 4.2?

Question

I upgraded to xCode 4.2 and it's new Storyboards feature. However, could not find a way to support both portrait and landscape.

Of course, I did it programmatically, with 2 views, one for portrait and one for landscape, like in old days, and:

if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) 
    {
        self.view = self.landscapeView;
    }
    else
    {
        self.view = self.portraitView;
    }

But I was looking for a way to do this automatically somehow. I mean, it's xCode 4.2 now, I expected more from it. Thanks all.

==================================
TEMPORARY SOLUTION:

I will present here a temporary solution. I say it's temporary, because I am still waiting for Apple guys to do something really intelligent about this.

I created another .storyboard file, called "MainStoryboard_iPhone_Landscape", and implemented the landscape view controllers there. Actually, it's exactly like normal(portrait) .storyboard, but all screens are in landscape mode.

So I will extract the ViewController from landscape storyboard, and when rotation occurs, just change self.view with the new viewController's view.

1.Generate Notifications when orientation changes:

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

2.Look for notifications:

[[NSNotificationCenter defaultCenter] addObserverForName:UIDeviceOrientationDidChangeNotification object:nil queue:nil usingBlock:^(NSNotification *note) {    
    // We must add a delay here, otherwise we'll swap in the new view  
    // too quickly and we'll get an animation glitch  
    [self performSelector:@selector(updateLandscapeView) withObject:nil afterDelay:0];
}];

3.Implement updateLandscapeView

- (void)updateLandscapeView {  
 //>     isShowingLandscapeView is declared in AppDelegate, so you won't need to declare it in each ViewController
 UIDeviceOrientation deviceOrientation       = [UIDevice currentDevice].orientation;
 if (UIDeviceOrientationIsLandscape(deviceOrientation) && !appDelegate().isShowingLandscapeView)
 {
     UIStoryboard *storyboard                = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone_Landscape" bundle:[NSBundle mainBundle]];
     MDBLogin *loginVC_landscape             =  [storyboard instantiateViewControllerWithIdentifier:@"MDBLogin"];
     appDelegate().isShowingLandscapeView    = YES;  
     [UIView transitionWithView:loginVC_landscape.view duration:0 options:UIViewAnimationOptionTransitionCrossDissolve|UIViewAnimationCurveEaseIn animations:^{
         //>     Setup self.view to be the landscape view
         self.view = loginVC_landscape.view;
     } completion:NULL];
 }
 else if (UIDeviceOrientationIsPortrait(deviceOrientation) && appDelegate().isShowingLandscapeView)
 {
     UIStoryboard *storyboard                = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
     MDBLogin *loginVC                       = [storyboard instantiateViewControllerWithIdentifier:@"MDBLogin"];
     appDelegate().isShowingLandscapeView    = NO;
     [UIView transitionWithView:loginVC.view duration:0 options:UIViewAnimationOptionTransitionCrossDissolve|UIViewAnimationCurveEaseIn animations:^{
         //>     Setup self.view to be now the previous portrait view
         self.view = loginVC.view;
     } completion:NULL];
 }}

Good luck to everybody.

P.S: I will accept Ad Taylor's answer, because, after much time waiting and searching for a solution, I finished up implementing something inspired from his answer. Thanks Taylor.

Answer 1

This is an old question but I read this earlier in the day and then had to spend a fair amount of time work out a better solution. I came up with this solution from hacking up the Apple Alternate View example. Basically it is serving up a modal view for the landscape view.

#pragma mark Rotation view control

- (void)orientationChanged:(NSNotification *)notification
{
    // We must add a delay here, otherwise we'll swap in the new view
    // too quickly and we'll get an animation glitch
    [self performSelector:@selector(updateLandscapeView) withObject:nil afterDelay:0];
}

- (void)updateLandscapeView
{
    UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    if (UIDeviceOrientationIsLandscape(deviceOrientation) && !self.isShowingLandscapeView)
    {
        [self performSegueWithIdentifier: @"toLandscape" sender: self];
        self.isShowingLandscapeView = YES;
    }
    else if (deviceOrientation == UIDeviceOrientationPortrait && self.isShowingLandscapeView)
    {
        [self dismissModalViewControllerAnimated:YES];
        self.isShowingLandscapeView = NO;
    }    
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
