I have an app with an UITableView at the home screen. I made this view to always be in landscape orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
If the user picks a row he will be taken to a UIPageViewController view. This second view can rotate to landscape and portrait. The problem is when I am in portrait mode on the UIPageViewController and I press the go back button, the first view which is supposed to be always in landscape mode now is in portrait. After I rotate it, it gets into landscape and stays there.
I was wondering maybe if there is a way to make my home screen go automatically into landscape when I go back to it.
Try the following
Create the view of your main screen in app in interface builder in Landscape mode.
Create uiview oultlet in interface class and connect it to above view.
IBOutlet UIVIew *myView;
Then in the viewDidLoad method set this
self.view = self.myView;
If you want to make a screen in a particular orientation then you can create a CustomNavigation controller and then present it in your app. You have to only return supportedInterfaceOrientations in this. If you want more detail and sample code click here.
Call shouldAutorotateToInterfaceOrientation manually when you go back. You can not force a "real" orientation change, that's a OS thing.
As said in the view controller programming guide, you can have a alternate landscape interface and before coming to home screen from any other view, you can check the orientation and push the corresponding interface onto the screen
Read this SO question and answer for better understanding of launching an app in landscape.Also go through above apple programming guide which i pointed to.
If you use the UINavigationViewController methods(pushViewController:animated: and popViewControllerAnimated:), the views will inherit the previous view's orientation.
On the other hand, if you use presentModalViewController:animated: and dismissModalViewControllerAnimated: methods, everything works perfectly. Hope this helped!
Use this, change the UIInterfaceOrientationLandscapeLeft to required orientation type as UIDeviceOrientationPortrait, UIDeviceOrientationLandscapeLeft etc.
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];

I have an application that uses portrait mode in the the view controllers except for one, that one page needs to be landscape only (landscape left or landscape right). How can I achieve that ?
I tried multiple solutions that say set the orientation mode for the Navigation Bar and the Application will turn but unfortunately that doesn't work for me. Also I tried manually rotating the view, it worked but when I click the text field to write something in it, the keyboard appears in the portrait mode rather than the landscape one.
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeRight];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
the above code works for me but only when I allow the app to rotate in landscape and portrait both but this is not what I want because this way all the pages can turn landscape from portrait.
EDIT:
My situation here is that I have been assigned with an already made project. The guy who has made this app had been using STNavigation Manager (i'm not exaclty sure what that is) rather than self.navigationController push and pop as stuff. So shouldAutoRotate and these delegates are not working in my app. Secondly he has also disabled the navigationBar and created his own NavigationBar.
If you enable the landscape modes you need in the application you can use the code you are using to force the app into the landscape mode you want and then force it back to portrait before you return to the screen in which you want to be portrait.
I found the best way is to create a subclass of UINavigationController that disallows rotation via
-(BOOL)shouldAutoRotate
Then in the one view i want landscape implementing the same method on the VC level returning true.
Use UIView's transform property to rotate:
-(void)viewWillAppear:(BOOL)animated
{
CGAffineTransform newTransform = CGAffineTransformMake(0.0,1.0,-1.0,0.0,0.0,0.0);
self.view.transform = newTransform;
}
I am working on a landscape view for a currently existing application. I believe I have autoRotate, supported interface, etc set up correctly, I am actually reusing code that works with a much simpler app. However when the simulator is rotated into landscape mode, the correct view loads, but the status bar and view stay with the short edge of the iPad. I've attached a screenshot and code. Is the problem with a view controller higher up in the chain, or the appdelegate? I've traced the called controllers in the debugger and it appears they are dismissed once this page is loaded. I am fairly new-ish to obj-c so it is possible this is something simple I am missing, but I have checked all attributes for the .xib file and everything looks copasetic.
Some of the code:
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;// | UIInterfaceOrientationMaskPortraitUpsideDown;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Overriden to allow any orientation.
return NO;
}![enter image description here][2]
-(void)orientationChanged{
UIInterfaceOrientation interfaceOrientation = [[UIDevice currentDevice] orientation];
if ((interfaceOrientation==UIInterfaceOrientationPortrait)||(interfaceOrientation ==UIInterfaceOrientationPortraitUpsideDown)){
self.view = self.portraitView;
} else {
self.view = self.landscapeView;
}
}
EDITS - This problem occurs on both iOS 7.1 and 6.1 and this is the first time any screen in the app supports a landscape view. To clarify the views, the portrait and landscape views are separate Views in single .xib file. The file owner class is set to the correct view controller class, and the parent view controller, a sales screen, should not rotate. It does not have a landscape view, but even with its autoRotate methods set to return YES the subview does not orient correctly.
Like 0x7ffffffff already said you need to allow rotation in your shouldAutorotate functions. Also you need to set up the supported rotation directions in your project setup.
First go to your project's settings:
Next you need to select all the orientations you want to support:
Another that is very important: ONLY the root View Controller will receive rotation events. If you nest a View Controller inside a View Controller then that nested Controller will not receive those events unless you wire them up manually from the parent. That's why I usually don't nest ViewControllers but use ad-hoc NSObjects or UIView implementations for nested views.
Last but not least: make sure your device is not rotation-locked: http://www.iphonefaq.org/archives/972915
The problem was occurring because a subclass of the customerView was not receiving the rotation notification. After tracking that class down it was a matter of setting up the NSNotificationCenter for orientation changes and then allowing autoRotation and supprotedInterfaceOrientations.
I've got a universal ipad/iphone app that allows the user to watch a video, which they can then expand into full screen mode.
I have implemented (void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration, and in that method I perform various setFrame calls on my view elements depending on whether they are in landscape or portrait orientation.
That all seems to work fine in normal use, i.e. rotating back and forth works fine.
But if the user starts in portrait mode, starts a video, goes to full screen mode, turns into landscape orientation, and then the video stops -- the elements are often not resized properly. They appear to be sized still as if they are portrait mode.
If I then turn to portrait mode, and then turn back to landscape, the view resets correctly.
The strange part is, I have implemented (void)exitedFullscreen:(NSNotification*)notification and in there I print out the orientation, and it's seen correctly. I also call my code to reset the view elements based on the current orientation, and I am still having this problem.
Another related issue is sometimes when dealing with rotation, my views will end up too far up the screen, actually going under the status bar at the top of the device.
Edit Here's the latest example. I rotate to landscape mode during full screen video playback, and then when I left full screen video, you can see the issue with the navigation bar at the top of the view.
One possible way to solve this is by presenting your view controller modally instead of using the navigation view controller.
Refer to Kenny's answer at Problem pushViewController from Landscape to Portrait
Your ViewController might not be rotating because another controller is the first responder. What you can do to avoid this is register the view controller to the device rotation changes and implement the rotation in the selector you call when you receive such a notification.
In appDelegate:
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
In your view controller
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(didRotate:)name:UIDeviceOrientationDidChangeNotification object:nil];
In did rotate you can check the orientation with
[[UIDevice currentDevice] orientation]
The navigation bar at the top of the view. I solved it, using this code ->
[[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
Using this after your rotation.
Mason, did you logged and checked whether your method willAnimateRotationToInterfaceOrientation:duration: gets called after each state transition?
To me this latest screenshot does not look like an orientation change issue.
The navigation bar is basically off by the status bar's height.
Possibly your position calculation fails because you are using the view's frame
while the fullscreen video (w/o status bar) is playing and this fails as soon as
the statusbar is back?
Your orientation may not get updated properly if there is another controller acting as a first responder. The best way to overcome this is to call the functions you use to orientate the screen at the method viewWillAppear: using the current orientation of the view controller: [self interfaceOrientation]
If you use a subclassed subview you may need to reimplement the methot layoutSubviews and call setNeedsLayout. Another thing that may be causing this is resigning the viewcontroller where you have the video as first responder (you mays search if somewhere you use the methon resignfirstresponder and try how it works without it). If this does not work, I don't know, this things may be very tricky and dependent on how you have implemented it. But for the things you say you do you should not need much code, since automatic rotation and resizing of views is handled now by the sizes inspector of the views editor.
I think that this should do.
I have setup a new iPad project to only support UIInterfaceOrientationLandscapeRight.
In my App Delegate I add a RootViewController to the window's rootViewController.
In this UIViewController (RootViewController) I have the following:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
I have also tried with:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
However, I am not able to get the correct dimensions for my app when I create and add subviews based on the dimensions of my view controller's view.
If I output self.view.frame for my view controller I get {{0, 0}, {768, 1024}}, but I would like {1024, 768} instead. If I can't when are the dimensions correct so I can create my views with them in mind?
Sorry if this has been asked a billion times, I've browsed lots of SO questions, but nothing has solved my issue.
I was running into the same issue, and what Ash Furrow said above seems to be correct; the orientation is set after viewDidLoad is called.
I was creating an iPad app that works in all orientations, but only the portrait orientations were getting set up correctly in my root UIViewController. In order to make the views layout correctly in landscape, I had to make sure the autoresizing masks on all my subviews was set to allow the view to adjust to landscape behind the scenes before being displayed to the user.
For example, I had a UIImageView that was the same size as the UIViewController's UIView. In order to get it to adjust correctly when rotating to landscape:
UIImageView *backgroundImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
backgroundImageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
[self.view addSubview:backgroundImageView];
Now the UIViewController can be configured in portrait orientation in the viewDidLoad method and rotate nicely to the portrait orientation before being displayed to the user.
EDIT:
Looks like the interface orientation is being set already in viewDidLoad
p (UIInterfaceOrientation)[self interfaceOrientation]
(UIInterfaceOrientation) $1 = UIInterfaceOrientationLandscapeRight
Here's my theory: interfaces on the iPad are, by default, 1024x768 if that have a status bar, which yours does. I believe that, even though the interface orientation is correct, it's not updating the view geometry until after viewDidLoad. I believe it has a very good reason for that.
If you look at the UIViewController Life Cycle docs, viewDidLoad is called as part of the set up of the view controller. After the view is loaded, willAnimateRotationToInterfaceOrientation: duration: is called to let your view controller know it's geometry is changing.
It's not so much an answer as an explanation. Hopefully this will help you architect a solution to get around this problem.
Begin answer that doesn't actually work:
In the info.plist for your project, open the "Supported Interface Orientations" option and delete the interface orientations you don't want to support. By default, all are supported:
That should clear it up.
I have a simple solution: the Apple default app templates work with XIBs for the main view controller. To solve your problem just open the main viewcontroller XIB and set orientation to "landscape".
As I usually don't use XIBs and create all UI elements programmatically. That's why I had the same problem in previous projects that really drove me crazy. I then solved it by hard-coding the frame width & height value - not the nice way.
I am creating an application with Landscape Right orientation. For that I set the Initial interface orientation property in info.plist file. Then in every view I handled
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return(interfaceOrientation==UIInterfaceOrientationLandscapeRight);
}
It works fine in simulator but in device its behave differently.
My first view is in proper orientation. There is is popover which display another view that comes in portrait mode. Still my status bar is in Landscape Right..
For navigating from one view to another view I am using..
self.window.rootViewController = self.myNav;
I have multiple navigation Controller and adding those using the upper code.
I am not getting what is the problem.
Any help will be appreciated.
EDIT: I had used
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
I never get this issue in simulator but getting this in device and not every time. I have used Supported interface orientations (iPad) too and set Landscape (right home button) value for item0.
Thanks In advance
You need to set the "Simulated Metrics > Orientation" property of your top view (in all your xib files) to be "Landscape". The default is portrait.
The question was answered pretty well here - Landscape Mode ONLY for iPhone or iPad .
I also have an app that like yours only supports UIInterfaceOrientationLandscapeRight. I haven't run into any orientation issues so far. I only have one UIViewController under the window. This UIViewController has its own UITabBar that I use to change pages. So, we change pages differently. I set my UIViewController using the rootViewController property of the window just like you, but again I only have one.
Also, I never had to do anything like the [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications] call that you included. Since you only support LandscapeRight orientation, you shouldn't care to be notified of changes.
EDIT
I created a sample project, which I can post if necessary, and I think I may know your problem. First - do you only encounter the sizing issue inside popovers? If so, then I don't think orientation is throwing you off but the popover itself. My sample project has 3 view controllers. The first loads the second by changing the window's rootViewController. That worked fine. The second view controller has a button to open a popover. This will show up wrong unless you set the contentSizeForPopover on the view controller as shown below:
- (IBAction) showVC3InPopover
{
UIViewController * vc3 = [[VC3 alloc] init];
/** Set the contentSizeForViewInPopover property to determine how
large the view will be in the popover! You can do this in the
init method(s) of the view controller if you prefer, it's just
easy to do here */
vc3.contentSizeForViewInPopover = vc3.view.frame.size;
[_popover release], _popover = nil;
_popover = [[UIPopoverController alloc] initWithContentViewController:vc3];
[vc3 release];
[_popover presentPopoverFromRect:_showPopoverButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
See if this fixes your problem. If it does, there are other ways to control the popover size, but this is just what I typically do. However, just know that the PopoverController ignores the size of the view in the viewcontroller you load.
How many views (or viewControllers) you have? You might need to implement this orientation logic in all those views??
