I have application that uses landscape right orientation.
In view controllers I use:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
But, If user locks iphone or ipad to portrait orientation, screen is displayed
as portrait, not landscape. Also, in info.plist file I defined only Right Landscape orientation as
supported one.
Try setting the UIInterfaceOrientation key in your Info.plist to UIInterfaceOrientationLandscapeRight. That should force landscape right orientation on launch.
The problem was in function viewDidLoad where another view controller is pushed into navigation stack immediately. If pushing action is delayed then landscape rotation will start and proceed, and also desired view controller will be pushed properly with landscape orientation.

I am making a view based application. For one of the xib files, I want it to only appear in landscape mode. And When i click a button in the first page it should automatically rotate to landscape and navigate to the new screen which should be in Landscape orientation.
How do i do this ?
If you are using UINavigationController then you will not be able to navigate from portrait to landscape, you will need to present your new view controller modally, not to push it
Check this answer Force UIViewController to only show in landscape mode
In the view that should be in landscape orientation , add this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
I have a simple navigation app that has 95% of all views displayed in landscape mode. With the one view that makes sense to only show in Portrait mode i have inserted the following code in:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
The problem is that when the app navigates to the view (from a landscape orientated view) it does not switch the orientation to portrait, only when the device is rotated will it snap into portrait and stay in portrait. Is it possible to force it to load in portrait mode on load of the view?
Thanks in advane
I think you should go through : shouldAutoRotateToInterfaceOrientation method of UIViewController Class.
This function returns YES if the orientations is supported by your UIView. If you return YES only to the portrait orientation, then the iPhone will automatically be put in that orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
When I navigate from one view to another view, I want to open the view in portrait view only.ie I am navigating from a first view (landscape) to second view. I want the second view to always be open in portrait view.In my case when I launch in landscape, the view is in portrait but the device is in landscape mode. The output I expected was if I open the view in portrait and and on rotating it to landscape with no rotation.
EDIT:
If you open the app in portrait and if you given auto-rotate as NO.Then if you rotate the device to landscape,then there will be no rotation in output.I want the same effect when loading a view initially in landscape.
I'm pretty sure you cannot use setOrientation anymore, since it is deprecated and apps have been declined for using it.
This may be an option for you:
http://www.iphonedevsdk.com/forum/iphone-sdk-development/33548-alternative-setorientation.html
It rotates the view using a transformation.
Okay so what you want to do is edit one of the functions in the view file. You want to set;
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations.
return YES;
}
From return YES to return (interfaceOrientation == UIInterfaceOrientationPortrait);
Then your view should only be in potrait.
Since iOS 3.2 the MPMoviePlayerController class allows to embed a movie in the view hierarchy.
Now I'm facing this issue: I create my portrait view by placing an instance of MPMoviePlayerController. When the user touch the "fullscreen" button this view enters in fullscreen mode but the view remains in portrait. When the user rotates the device the fullscreen movie view is not auto-rotated as my app forbids landscape interface orientation.
So in order to allow auto-rotation of movie player fullscreen view, I changed my view controller shouldAutorotateToInterfaceOrientation: method to return YES for landscape if - and only if - the movie player is in full screen mode.
This works perfectly: when the user enters in full screen and then rotates to landscape the player is auto-rotated to landscape and fills the entire screen.
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
//return (interfaceOrientation == UIInterfaceOrientationPortrait);
if(UIInterfaceOrientationIsPortrait(interfaceOrientation)) {
return(YES);
}
if(UIInterfaceOrientationIsLandscape(interfaceOrientation)) {
return([movieController isFullscreen]);
}
return(NO);
}
Now the issue arises when I touch the "Done" button in the full screen view while remaining in landscape. The full screen closes and then what I see is my original view autorotated: but I don't want this auto-rotation.
A partial, but not acceptable solution, is to listen for "MPMoviePlayerDidExitFullscreenNotification" and, if the interface is rotated to landscape, force re-orientation to using the undocumented and private function:
[[UIDevice currentDevice] setOrientation:UIDeviceOrientationPortrait]
This works but is not acceptable as usage of this method is forbidden.
I tried to force orientation using [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait] but as I'm in a Tab Bar this doesn't work (the UITabBar remains Landscape-sized).
Thanks for your help
You can use a separate view controller for MPMovieplayer. You don't have to override the
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
in the original view controller.
if you are using MPMoviePlayerViewController, everything is already set nicely for you, as the method shouldAutorotateToInterfaceOrientation: will return YES by default. You can use it as a subview or present it modally by calling
presentMoviePlayerViewControllerAnimated:
Check this out: MPMoviewPlayerController fullscreen playback rotation with underlying UIViewController with portrait mode only (rotation disallowed)
Maybe a little different problem, but solution may be the same.
I am making a TabBar based universal app. I have added few extra tabs and changed the viewController to navigationController. Now when i am trying to rotate the view from portrait to landscape, its rotating the inside view but tabBar does not rotate and it stays at the same place ie at the bottom of the portrait mode where as every other UI are rotating properly.
Make sure the controller not supporting the rotation (respectively its owner) overrides shouldAutorotateToInterfaceOrientation and returns YES for all orientations.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
#pragma unused(interfaceOrientation)
// Overriden to allow any orientation.
return YES;
}
