I have a table view that contains an instance of MPMoviePlayerController as the table header and when the user presses my custom overlay button, the video expands to full screen. The aspect ratio of the video is such that in portrait mode it is very small, and I imagine most users will rotate to landscape.
The problem is that I want to allow rotation when the video is full screen but not when it exits. My underlying table does not support landscape. Is there a way to support rotation only when full screen? I thought this would be a standard component of MPMoviePlayerController.
I'm using SDK 5.0, but it was originally built with 4.3.
Have you tried subclassing the MPMoviePlayerController MPMoviePlayerViewController class, and overriding the method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (!self.fullscreen) {
return UIDeviceOrientationIsPortrait(interfaceOrientation);
}
return YES;
}

You cannot subclass UIImagePickerController, but surely there is clean(not saying obvious or easy) way to keep camera feed as background of UIViewController and just make UIImagePickerController overlay to rotate like it would respond to shouldAutorotateToInterfaceOrientation: ?
I just want to UIImagePicker stay in its beloved portrait orientation, but I want rotate my UI buttons that I put into camera overlay. What I have now, is changing each element's orientation with CGAffineTransformMakeRotation() so it always stays at the same place, but rotates around each center.
I downloaded Layar app and the somehow achieved it... camera feed stays and UI buttons rotates (like UIViewController's style).
edit: I have to use iOS 5.1 and Xcode 4.2
edit2: for now I have this int DIRECTION and depending on what is the current orientation of the device I assign from 0 to 3, so I can decide with what angle to rotate all UI buttons. I do this inside shouldAutorotateToInterfaceOrientation: which is returning only YES for portrait and upside portrait.
You have to put constraints on the buttons and picker view.

Hope this will help but you have to go through it thoroughly.
I've encountered a strange issue, which I need help resolving. My app is always run in portrait mode - I explicitly want it to be that way. In one place in the app I have a UIWebView, which works just fine, as expected. This web view is not shown all the time but is dynamically added to the main view and removed based on user actions (i.e. it's only visible when I need it to).
Now, sometimes in this view I may have a youtube video. The WebView simply contains the <iframe> for the youtube embed. When a user clicks on the video preview frame in the webview, a full-screen video viewer is launched to play the video - which is just fine.
However if during the playback the user rotates the phone, the full-screen video player is rotated and the video is played in landscape mode. Now the video is stopped and the user presses "Done" button without rotating the phone back to portrait mode, the video player is closed and the user returns to my app - however now my layout is also rotated! Not just the video view, but the entire layout - with toolbar, navigation controller, etc.
I don't want any rotation! I just want everything in my app to remain in portrait mode! Moreover, now even if the phone is rotated back to portrait, the app stays in landscape mode.
Note that I only tested this in a simulator so far, as I currently don't have a physical phone to test. I created a simple (bad quality!) video (just filmed the simulator on my screen with an old phone camera) to demonstrate the issue - the video is here: http://shchuka.com/hosting/rotation_problem.mp4
Any ideas what I can do about it?
Add this in, or change it:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (UIInterfaceOrientation == UIInterfaceOrientationPortrait);
}
That will prevent all rotation and the app will only work in portrait mode. You can place the return statement within IF statements to allow rotation under certain circumstances.
I sometimes add views to the appDelegate window when I want them to be above everything else, and an annoying side-effect has been that I have to explicitly call my own rotation code as there is no VC as such to deal with it. On the plus side, it might mean that it could be ideal for your needs -
[[[[UIApplication sharedApplication] delegate] window] addSubview:myWebView];
...depending on your app's orientation, etc, before you load the view in the first place, you might need to rotate the webView before displaying it.
We are just putting user input into our game so the user can enter email address etc. The entire game is Gl with no iOS UI at all. The EAGLView does not change orientation, it is always in portrait, however the game is in landscape and we handle this with a camera transform.
We want to bring up the iOS keyboard and overlay a UITextView for the text input. The UITextView is a subview of the EAGLView. Obviously it, and the keyboard, shows up in portrait as the EAGLView is in portrait.
Without having to change the EAGLView to landscape is there any way I can force the UITextView and the keyboard to show up in landscape orientation?
If I do change the orientation of the EAGLView to landscape to get this working, is there any hit on performance? I have read several times that orienting a GL view in anything other than the default portrait view will give a performance hit, although I can't find any solid evidence of this.
Thanks,
We think we have come up with a solution for this. We are doing two things, one for the keyboard and the other for the UITextView.
For the keyboard we are setting the status bar orientation. The keyboard follows when set.
[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
And to get the UITextView to orient correctly we apply a transform to subviews of our EAGLView, which in this case is only the UITextView, as follows.
CGAffineTransform aTransform = CGAffineTransformMakeRotation(M_PI / 2);
[glView UpdateSubViewTransforms:aTransform];
This literally adds a 90 degree rotation to the view.
This has been tested on iPad & iPhone 4 with iOS 4.3, and on iPhone 3G with iOS 3.13.
Total Objective-C/XCode N00b here but I am attempting something, which I assume is simple. I have an app that is written for the iPhone, I don't allow auto orientation and only have the main interface locked into portrait. When the user plays a video in the app I would like to allow them to auto rotate the device from portrait and watch it in landscape (should they choose to do so, I don't want to force this). Once the user presses "Done", I would like to force them back into portrait (even if they are holding the device in landscape) as the interface is only laid out in that orientation.
I've tried using the MPMoviePlayerController and MPMoviePlayerViewController and I am not sure which will give me the leverage/methods I need. I am basically just looking to allow shouldAutorotateToInterfaceOrientation to return yes only when the MPMoviePlayerController view is visible.
Any help MUCH appreciated. Thanks.
I used this code example and it worked perfectly. I think you'll have to set the orientation in the super class.
I have an app designed for iPhone that makes use of the UIImagePickerController.
The app run in landscape only up until the image picker comes into view in its default portrait.
Problem 1:
On the iPhone when I rotate the device to portrait to view the image library the image picker view seems to do a flip as if rotating from landscape to portrait?
Problem 2:
I get the dreaded warning Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations.
Problem 3.
on the iPad when selecting an image the image picker is dismissed and the view is back in landscape but ...... if I then do anything that requires alert view or the keyboard they appear as if the device is in portrait? This does not happen on the iPhone???
I know problem 2 is a long running issue but please can anyone help with problems 1 & 3?
Thanks
number 3 resolved :-)
"The keyboard will show up in the orientation of the statusbar, which doesn't always change with rotations for some reason. So if you want to display that view only in landscape set [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeLeft; or whichever orientation you want to prefer in your viewWillAppear method."
