setStatusBarOrientation:animated: not working in iOS 6 - objective-c

I've used this code to force an orientation change back to portrait when the user is finished watching the video (it allows viewing in landscape mode), before popping the video view controller off the navigation controller:
//set statusbar to the desired rotation position
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];
//present/dismiss viewcontroller in order to activate rotating.
UIViewController *mVC = [[[UIViewController alloc] init] autorelease];
[self presentModalViewController:mVC animated:NO];
[self dismissModalViewControllerAnimated:NO];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
This worked perfectly until iOS 5.1.1. I've even tried to use the new present/dismiss methods after reading in another post that those should be used now:
[self presentViewController:mVC animated:NO completion:NULL];
[self dismissViewControllerAnimated:NO completion:NULL];
The problem is it doesn't work at all. After I rotated the video viewer to landscape and then pop it, my settings view (table view controller) comes back, but also in landscape mode.
I've even tried the tip from Here
"The setStatusBarOrientation:animated: method is not deprecated outright. However it now works only if the supportedInterfaceOrientations method of the topmost full screen view controller returns 0. This puts the responsibility of ensuring that the status bar orientation is consistent into the hands of the caller."
So I've experimented with setting a flag to force supportedInterfaceOrientations to return 0 (before calling the first code block above) but it doesn't work either.
Does anybody have a solution for this?
Thanks for your time and effort.

setStatusBarOrientation method has changed behaviour a bit. According to Apple documentation:
The setStatusBarOrientation:animated: method is not deprecated
outright. It now works only if the supportedInterfaceOrientations
method of the top-most full-screen view controller returns 0

Your root view controller should answer false to the method shouldAutorotate in order that your app responds to setStatusBarOrientation:animated
From Apple Documentation: "if your application has rotatable window content, however, you should not arbitrarily set status-bar orientation using this method"
To understand that, put a breakpoint in the shouldAutorotate method and you will see that it is called juste after setting the status bar orientation.

Here is how I fixed.

The current question is linked with the question from the url above.
The statusBarOrientation is a real problem in ios6.

Setting frame dose not working in OS7

I am trying to set the frame of my superview when presenting a view, the code i used is
navigationController.modalPresentationStyle = UIModalPresentationPageSheet;
navigationController.view.superview.frame = CGRectMake(32, 20, 1024-(32*2), 748);
[[self navigationController] presentModalViewController:navigationController animated:YES];
the code was working fine in OS6. but when come to OS7 its not working.
This method has been deprecated in iOS 7.
- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated NS_DEPRECATED_IOS(2_0, 6_0);
Use the following :
- (void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion NS_AVAILABLE_IOS(5_0);
If it was working in iOS 6 it was by chance. You are depending on the private view hierarchy used by iOS when presenting modal view controllers, and you've just found out why this is a bad idea. It can, and does, change without warning or documentation. See also, the view hierarchy of a UITableView between iOS 6 and 7.
If you want to make your own style of presented view controller it is safest to write it yourself from scratch rather than hijack one of the existing ones. Try using the custom style of presentation and writing a transition delegate.
Ok i found a solution.,
BOOL ios7 = [UIDeviceHardware isOS7Device];
if(ios7){
navigationController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
}
Now it works fine. :)

Troubles with UISearchBar \ UISearchDisplayViewController

I'm having a hard time with my SearchDisplayViewController on iOS 7.
I have a searchBar hidden over a UITableViewController, like
self.tableView.tableHeaderView = searchBar;
Problem is that when I tap on the searchBar to type in something, then the view starts greying out, and I quickly tap the screen in a random point to dismiss it, coming back to the tableView, the searchBar disappears. Totally. Only on iOS 7 though.
Debugging it, the frame is always the same: 0,0,320,44. But the bar is invisible!
Also tried to do
self.tableView.contentOffset = CGPointMake(0,self.searchDisplayController.searchBar.frame.size.height);
still disappears when I do it quickly.
On iOS 6 it works just fine. Problem is only with iOS 7 as far as I'm seeing.
I don't know what it depends on, has anyone encountered the same problem I have?
As of Double tap UISearchBar with search delegate on iOS 7 causes UISearchBar to disappear, I found the workaround to actually work and solved the bug - for now.
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[self.tableView insertSubview:self.searchDisplayController.searchBar aboveSubview:self.tableView];
}
}
I encountered the same issue, and noticed that searchDisplayControllerDidEndSearch was being called twice. The first time, the superview of self.searchDisplayController.searchBar is the UITableView, and the second time it's still a UIView.
With the accepted answer, I worry about unintended consequences or unneeded overhead from re-inserting the subview every time the search bar is double-tapped, and I also worry about it breaking with future iOS versions. Fortunately, we can take advantage of the superview strangeness like this:
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller {
if (self.tableView != self.searchDisplayController.searchBar.superview) {
[self.tableView insertSubview:self.searchDisplayController.searchBar aboveSubview:self.tableView];
}
}
If I had to guess what was happening, the UISearchBar is automatically creating a temporary UIView as its superview when it's active – this is the view seen when the search is being performed. While the UISearchBar is being dismissed, the superview gets set back to be the UITableView it had before, unless it gets dismissed so quickly that it was never properly initialized, in which case it cleans up improperly and the UITableView never gets the UISearchBar back as its child.
This solution still isn't ideal, and I think Apple must be doing something different in its own apps because their search bar UX feels a bit better. I think it would be better not to handle the second tap in the first place until the UISearchBar was ready. I tried using the other UISearchBarDelegate methods to do this, but I couldn't find an appropriate hook to override the current behavior.
I had the same problem with iOS 7 and I solved it from the apple documentation. The error most people do is that they associate the UISearchBar variable to the self.searchDisplayController.searchBar as the same...! NO NO..! They are 2 different things!!! UISearchBar should be declared and initialized and then wrapped into self.searchDisplayController as searchBar then later wrapped into self.tableView.tableHeaderView by so doing it will not disappear!!!
self.searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
self.searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchDisplayController.delegate = self;
self.searchDisplayController.searchResultsDataSource = self;
self.searchDisplayController.searchResultsDelegate = self;
[self.searchBar setPlaceholder:#"search the hell in me"];
self.tableView.tableHeaderView = self.searchDisplayController.searchBar;
More refined approach for #lehrblogger solution:
- (void)addSearchDisplayControllerBackToTableView {
if ([self.searchDisplayController.searchBar isDescendantOfView:self.tableView] == NO) {
NSLog(#"Search bar is not in current table view, will add it back");
[self.tableView insertSubview:self.searchDisplayController.searchBar aboveSubview:self.tableView];
[self.searchDisplayController setActive:NO animated:YES];
}
}
Reason for this approach: While searching the search bar is moved to search container and the superview of search bar is always some other view other than current table view.
Note: This will dismiss the search, because user tapped more than once on search bar.

Application tried to present modally an active controller : UIImagePickerController

I'm struggle at this for 2 days and believe that this is the moment I should call for help. After I search SOF for a while, none of any answer could solve my problem. Here are my application ...
In the application,
Device is iPad, iOS 6
RootViewController is NavigationController
TopViewController is TabBarController
In this TabBarController, I present a popoverController from right bar button of navigation bar
In presenting popover there is a button to allow user to pick image from by taking new one or pick from existing.
To pick new one, I presentViewController UIImagePickerController to allow user to take photo with divice camera. presentModalViewController:animated: if iOS < 6, and presentViewController:animated:completion: for iOS > 6
I also hide Status Bar before presentation
To select from existing photo, I do presentPopoverFromBarButtonItem:permitArrowDirections:animated:
PopoverViewController also referencing by A TabBarController
Here is the issue
Present UIImagePickerController will always failed if user try to pick new one first with exception "Application tried to present modally an active controller <[name of view controller that try to present]>"
BUT, if user try to pick image from camera roll for once and then try to take new one again, it won't fail.
Here are what I tried
present from RootViewController
present from TopViewController (TabBarController)
present from popoverViewController itself
present from a tab of TabBarController
hide popoverViewController before presentation
resignFirstResponder from a textField in popoverViewController
Here is the current code I'm using
// PopoverViewController, presented by a tab in TabBarController
- (IBAction)takePhoto:(id)sender {
[self.delegate takePhotoWithDeviceCamera];
}
// A Tab in TabBarController, delegate of popoverViewController
- (void)takePhotoWithCamera {
[[UIApplication sharedApplication] setStatusBarHidden:YES];
if ([UIDevice OSVersion] < 6.0) {
[self presentModalViewController:cameraPicker animated:YES];
} else {
[self presentViewController:cameraPicker animated:YES completion:nil];
}
}
Any idea what would cause this error? Any suggestion are welcome. Thank you.
Got the same trouble than you and finally got the solution based on #CainaSouza's answer. I've been working with Xamarin.iOS so I'll make my answer in C#, but it can be easily translated to Objective-C.
I'm using the same code as #CainaSouza to call the controller:
UIApplication.SharedApplication.KeyWindow.RootViewController.PresentViewController (customController, true, null);
And then I add the following code to my custom RootViewController:
public override void PresentViewController (UIViewController viewControllerToPresent, bool animated, Action completionHandler)
{
if (PresentedViewController != viewControllerToPresent) {
base.PresentViewController (viewControllerToPresent, animated, completionHandler);
}
}
The trick is to check if you haven't presented that UIViewController before.
I know it's an old question, but hope it will help someone. :)
Present the imagePicker controller in a popoverController(in case of iPad). This will not give you that error.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:self.selectedImageView.bounds inView:self.selectedImageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popOver = popover;
}
else {
[self presentModalViewController:picker animated:YES];
}
Best Regards.
Have you tried to present it like this?
[self.view.window.rootViewController presentModalViewController:cameraPicker animated:YES];
My guess is that the cameraPicker instance is not correctly allocated/released. Try creating the cameraPicker inside your - (void)takePhotoWithCamera method rather than relying on a previously created instance. You'll get a handle to the picker instance in the callback methods...
I had the same problem - I wanted users to take photos using a full screen view (i.e. call presentViewController and pass UIImagePickerController controller instance) and select existing photos from a popover (I associated it with a popover using initWithContentViewController). I reused the same instance of UIImagePickerController for both camera and popover and it threw the same exception if I tried to run a camera before opening a popover.
I turned out to cause a problem and my solution was simply to have two instances of UIImagePickerController - one for camera (which I presented from a main view) and another one for popover. It works so far. :-)
Not sure if it is still actual for the original poster, but hopefully it will help anyone else who encounter this discussion.

modalViewController presented from UISplitViewController comes up as the wrong orientation

I have a UISplitViewController that is set at the rootView of my application. When viewDidLoad is called in my left view controller I do a check, then present a modal view controller using the following:
SiteConfiguration *config = [[SiteConfiguration alloc] initWithStyle:UITableViewStyleGrouped];
config.firstLoad = YES;
UINavigationController *configNav = [[UINavigationController alloc] initWithRootViewController:config];
if ([Utility isIpad]) {
configNav.modalPresentationStyle = UIModalPresentationFormSheet;
configNav.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[[AppDelegate instance].splitViewController presentModalViewController:configNav animated:YES];
} else {
[self presentModalViewController:configNav animated:YES];
}
If the iPad is in landscape mode while the app loads, the modalView is shown with an incorrect orientation:
I can rotate the iPad to fix this, but WHY does it load up wrong? I have shouldAutorotateToInterfaceOrientation: returning YES in my SiteConfiguration viewController. What could be causing this?
Be careful of where you choose to present your modal controller.
I've had experience with some custom modal controllers and setting the orientation of the modal controller (and its shadows!) in
- (void)viewDidLoad:(BOOL)animated
didn't always behave as expected.
Put your code (presentModalViewController:configNav animated:YES) in
- (void)viewDidAppear:(BOOL)animated
instead. (Do this as well with any code that sets a subviews frame or does any manipulation of layers, e.g. the shadow layer and shadow properties).
As far as I can tell, the rotation may not be apparent to subviews of the rotated view until after - (void)viewDidLoad:(BOOL)animated due to threading issues (one thread may start drawing your subview or modal controller's view before rotation is passed down to the subviews (and modal controllers) by the main thread). Someone with more experience with threads than myself might be able to shed more light on this.
shouldAutorotateToInterfaceOrientation: doesn't actually rotate the interface, the app does that upon receiving a UIDeviceOrientationDidChangeNotification notification.
Try adding a check for the device orientation in the -(void) viewDidAppear:(BOOL)animated method.
To force an interface rotation, use the following piece of code.
UIDeviceOrientation toInterfaceOrientation = [[UIDevice currentDevice] orientation];
[UIApplication sharedApplication].statusBarOrientation = toInterfaceOrientation;

willHideViewController not called when switching to view in portrait mode

My iPad app uses the standard UISplitViewController. My problem is, if I
Rotate to portrait, I put a Popover button for the Master list - Fine
Select an item via the popover, that changes the detailview (This uses a prepareForSegue which sets self.splitViewController.delegate = newViewDetailViewController;
The resulting detailview is now missing a popoverbutton. If I rotate to landscape, the master list appears. If I then again rotate to portrait, a popoverbutton appears.
So - How can I ensure willHideViewController will be called on viewDidLoad, for example?
I can detect what the orientation is, but I still need the barbuttonitem and popovercontroller needed in
- (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
For now I am following Apples MultipleDetailView example as suggested here.
But since I am having multiple MasterControllers as well, it's a real hassle to store (a static) pointer to the popoverbutton item and setting it every time I push a level on my masterview controller.
Hopefully, someone has a good way of solving this problem :-)
I ran into the same problem and finally figured out what was missing. There is a little code in the AppDelegate to performs some initialization. It is in the didFinishLaunchingWithOptions method. Here is the code that goes in there:
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
They're all important to operate the split view controller, but the last line is the most line for getting the method to fire is the last one. I am building a universal application and this was missing. To ensure that it didn't affect my iPhone side I wrapped it in a UI_USER_INTERFACE_IDIOM check.
