    Hi,

    I have this crash on iOS 8.2 (iPhone6 plus) when I build my roject (and Unity is set to "Auto Rotation"...):





    Somebody can help me ?

    Thank you very much.

    Best regards,

    AB

    Could you please submit a bug and attach a small reproduction project to it? Thank you

    Hi,

    I'm sorry but I solved it yet : I just changed the orientation setting in the build setting.

    Sorry

    I'm also experiencing this problem. The project is set to build with Auto Rotate as the desired orientation. The main menu selection screen will operate in either orientation. However, since this project is a set of mini-games, some designed for portrait and some for landscape, periodically the orientation will change and lock. If I'm in portrait, load one of the games that's landscape, and then rotate the device while the game is loading, I get the same crash as above.

    It's being caused by line 102 of the UnityViewControllerBase.mm file, in which it performs an assert to check for auto rotation. If I comment out this line in the Xcode project, the app works as expected, so it seems this assert is not behaving as intended. Is there a way to keep this line commented out as part of the build process, or is there another setting I can use to prevent the assert from failing? It is a requirement of these games that we be able to prevent auto-rotation at some times but not others.

    that's kinda interesting - it should actually switch directly, bypassing "auto-rotating" view controller.
    can you bug report with small repro? (we dont need your mini-games, just setup - so empty scenes with orientation logic would suffice).
    And yes, i would say that if you tested, commenting assert should be more or less fine

    Sure thing, Alexey, I can file a bug report. In the mean time, is there a way to automate commenting of that assert so that it's part of the build process? We're using UCB for most of our builds so we can't really manually remove it each time.

    I found a good post-process example out there from one of the UCB guys and modified it to suit my needs. Posting it here in case it's helpful to someone with this specific problem.

    FYI you want to drop that script in an Editor folder somewhere in the project.

    Thank you for this - just lost a day to this issue in a live app. Here's hoping I can get Apple to expedite the review of the fixed version!

    You deserve a medal! Had exactly the same problem (for the same reason, multiple mini-games :p). Also needed things to work with Cloud Build, so your automatic commenting script is perfect! So rare to come across a solution like this where someone has also gone to the effort of writing (AND SHARING) their fix like this. So rare that this is my first post here after so many years of lurking for solutions ;)

    Cheers!

    Looking at UnityViewControllerBaseiOS.mm:107 :

    NSAssert(UnityShouldAutorotate(), @"UnityDefaultViewController should be used only if unity is set to autorotate");

    But all builds succeeded on XCode :( with just warnings related, from Classes/UI/UnityAppController+ViewHandling.mm:

    Incompatible pointer types assigning to 'UnityViewControllerBase *' from 'UIViewController *'

    I need to change device orientation in my application at runtime, probably assigning Screen.Orientation to some values generate this crash.

    Any solution? I don't want to remove asserts from mm files.

    Thanks!

    I am using Unity 5.3.1f1, Xcode 7.2 (7C68)

    Updated the post-process commenting script that KAKE shared -- it fixes a few issues:
    • The filename containing the offending NSAssert changed in December 2015 with Unity 5.3.1 due to tvOS support being added -- the script now handles Unity versions before and after this change.
    • Changed it to work with local builds instead of UCB.
    • Added a log warning if it failed to replace the string.
    • The post-process script would keep re-commenting the line if you Build -> Appended. It no longer does this (but at the expense of a more fragile search string.)
    Hope this helps someone else!

    Hi,

    It looks like following issue could be reproduced via following code:

    Code (CSharp):
    1.  
    2. // Current orientation is Landscape and we want to set it as Portrait:
    3. Screen.orientation = ScreenOrientation.Portrait;
    4.  
    5.  
    This issue was fixed in the following way: before Autorotate configuration we should set Screen.orientation to Autorotate (but not Portrait or Landscape):

    Code (CSharp):
    1.  
    2. // Current orientation is Landscape and we want to set it as Portrait:
    3. Screen.orientation = ScreenOrientation.AutoRotation;
    4.  
    5.  
    Hope it will help somebody :)

    We are also seeing this crash in our live game on Unity 5.4.4p3. We are not able to repro, but it is definitely happening to users. Is anyone from Unity looking into a fix for this?
