I'm building a more or less complex app, but I'm quite new to this. I've created my own ABCViewController, which works fine with the MainWindow.xib (also in landscape mode), but now I want to create a UITabBarController (without code) which should be shown up before the ABCViewController. I simply tried using the storyboard, but when I run the app, the UITabBarController is in Portrait. The attributes inspector in storyboard is set to landscape for all my view controllers. Is it possible to edit the shouldAutorotateToInterfaceOrientation method for the UITabBarViewController, which exists only in storyboard? I've also set everything to landscape in the Info.plist!
EDIT: Solved. I created the Vvew controllers which are shown in the tab bar controller, and then I used the shouldAutorotateToInterfaceOrientation method and returned YES (not (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)) in every view controller.

I am trying to set a UIWindow in MainWindow.xib into landscape mode. Unfortunately, this option is greyed out in Interface Builder. I have a Navigation Controller within the same NIB that can be set to landscape, but this ends up looking awkward in Interface Builder, as the Nav Controller is set to landscape but the containing window is in portrait.
What's worse is that I can't get the window to run in landscape during runtime. I have this code in the view within the nav controller:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
I don't know how to specify this for the containing window though. I have set the orientation in the plist but this doesn't seem to make my view display in landscape.
From what i can see, it seems like you want your first view controller to be in landscape mode, when displayed.
For this, you need to set the "Initial orientation" in your info.plist file. There is a key for this.
Thus, what you need to do is, Make your xib in landscape mode, implement the method as you have done above and set the initial orientation to landscape in plist.
I faced a problem with the UIWindow being forced into portrait mode as well. My solution was to use another view level between the window and the views I was manipulating. Though not a perfect solution it worked. I hope you get it worked out.
I have a view controller which manages a view.
I'm adding the my view controller subclass as a subview of the window swapping out another view.
I'm running landscape mode on an iPad.
The view apparently doesn't know that its in landscape mode. Its frame is confused.
Is there something I can/should do to tell it that its in landscape, and/or that the orientation has changed. How does this normally happen. Why isn't it happening?
I used to have my view controller within a UITabBarController and it worked fine there.
Override:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return YES;
}
Your ViewController is not getting rotation events because you have not presented the viewController but have added the viewController's view in the view hierarchy.
Your Tab bar controller previously used to take the responsibility to forward the rotation events to the view controller which it manages, that was how it used to work.
I would though suggest that swapping the view out of window is a bad idea. Instead you should have a main viewController which accepts the rotation events and then swap the view within this viewController based on the current orientation. Consider re-desiging before you code further.
My problem was that my storyboard was overriding my existing custom coded app delegate. After I deleted the story board file, and custom generated view controller code, it worked for me.
Quick problem:
I have an UITabBarController with 2 navigation controllers [lets call them Left and Right Controller]
On the default selected Left Controller I can push a new View Controller that detects interface orientation.
On the Right Controller I can push the same View Controller but it won't detect interface orientation, or for that matter, It won't even go into the shouldAutoRotateInterface method at all T___T
Haaalp!!
If it is of any relevance, the View Contoller that I'm pushing use the hidesBottomBarWhenPushed property.
Most likely this is your problem:
Tab bar controllers support a portrait
orientation by default and do not
rotate to a landscape orientation
unless all of the root view controllers support such an orientation.
When a device orientation
change occurs, the tab bar controller
queries its array of view controllers.
If any one of them does not support
the orientation, the tab bar
controller does not change its
orientation.
The solution is to override the following method on every view controller leading to your view:
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation {
return YES;
}
For example, instead using the default UITabBarController in IB, replace it with your own subclass containing just the method above.
I'm a bit late to the party on this, but I ran into a problem with autorotation at startup for a tab bar app I wanted always to run in portrait.
The app's plist has the necessary settings to both start in and only allow portrait mode, and all my view controllers only allow portrait mode. Yet, when I started the app holding my iPhone in landscape, the app started in portrait, but then rotated to landscape!
Rather than subclass UITabBarController, I simply overrode UITabBarController's shouldAutorotateToInterfaceOrientation: method using a category on class UITabBarController. I included this code in my app delegate:
#implementation UITabBarController(UITabBarControllerCategory)
-(BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
Works beautifully, and is quite lightweight.
does your uitabbarcontroller implement the auto rotate? any child viewcontroller that wants to implement autorotate has to have its parent implement autorotate.
All my app is in landscape mode .In some point I switch to a screen with Tab Bar Controller , but it's been placed like in portrait mode.I subclassed the UITabBarController and override the method "shouldAutorotateToInterfaceOrientation" to return YES always but because the app is already in landscape , this method is not being called.
does anyway have an answer to this?
thanks

You shouldn't have to subclass UITabBarController. The tab bar will autorotate to landscape, if all it's subviews support landscape. Just make sure all tabs support landscape orientation and you should be fine afaik.
Rengers is right, just make sure all tab views have YES in their respective shouldAutoRotateToInterfaceOrientation overrides. Depending on how you setup your app, check if any parent views have the shouldAutoRotateToInterfaceOrientation overrides. If so, it might be worthwhile commenting them out and leaving the overrides for the tab views only.
(By the way I develop without Interface Builder)
If you have a tab bar app that autorotates, so all the autoresizing masks are set, how do you make it work with all the views? Like if one view autorotates to landscape, you select a different tab in the tab bar, and the view associated with that tab comes up, and its all messed because it never got autorotated, it got initialized with the frame that makes it fit in portrait mode, even though the autoresizingmasks are set to have it look fine in landscape, it never got rotated. Whats the solution? (By the way, I'm lazy loading the views, so the only view loaded at any given time is the view(view controller's view) associated with the selected tab).
Does declaring all the required orientations in the didrotatefrominterfaceorientation method in every view controller you are using fix the problem?
e.g. your main view, with the tab bar is called "mainView", and when you choose a tab, it loads a view called "firstView", does the "firstView" view controller have the orientations set?
If a view controller is not loaded, it won't be able to respond to autorotation messages. So in your view controller, when it's loaded from the nib, it should check the orientation and resize and move things as necessary.
