iOS Landscape Orientation Launching upside down - Unity 5.2.1

When building a simple Unity 5.2.1 project for iOS deployment we set the default orientation to auto rotate and then allow both landscape left and landscape right. When launching the app with Xcode the app will always start in landscape left which means if the player is holding it in landscape right it appears upside down at first and then flips over after a brief moment.

Is anyone else seeing this? We've tried it with a brand new project and still get the same results. If both landscape modes are supported (no portrait) it always defaults to just one of them no matter which way it's being held at launch.

We're using the most recent version of Unity (5.2.1), the most recent version of Xcode (7.0.1), and are running on OS X El Capitan.

Any help?
Thanks

 

Yeah, same here. Have no clue how to fix. I _think_ it started @5.1 version.

 

We've got even worse bugs - the launch screen image displays correctly to start with and then rotates 90 degrees the wrong way showing the landscape image cut off. There's a rolling thread on it all here.

 

Hey, I am also experiencing this issue and have logged a bug report as I was unsure if the previous posters logged one and I couldn't find any on Issue tracker.

I have found a temporary fix however, disabling "Use Animated AutoRotation" fixes the issue, although you can see the app in the wrong orientation briefly before it correct's itself. This obviously is not ideal as you do not have the nice animated rotation affect that users would be accustomed to.

 

I have similar issue or same issue with 4.6.9: http://forum.unity3d.com/threads/iphone6-unity-4-6-9-splashscreen-issue.360944/

 

Nope, it's occurring on iPad Air and iPad mini for us, although our testers are saying it's happening on all iPad devices, but I cannot confirm this. Our app is iPad only, so have not tested on an iPhone.

 

Happening for me too.

 

So since the problem existed in a completely new empty Unity project as well I decided to start going in and debugging Unity's code from within Xcode. I came across some worrying TODO comments in some of the code. SplashScreen.mm has a "TODO: implement on iPads." Hmmmmmm.... doesn't sound good right. Then a little further down there's "FIXME: check on iPad" (currently I'm on Unity 5.2.2f1 and this line is at SplashScreen.mm line 289) I found that if I comment out the FIXME line then the problem of starting upside down goes away. Only problem is that the splash screen is just black at first. Seems like the lesser of two evils though, so that's what I've been doing. Hopefully Unity addresses these TODOs and FIXMEs soon.

 

Thanks for the information, then they should have really shared this in the release notes as a KNOWN ISSUE.
Did you change this within Xcode once Unity made a build?

 

@mpaxman Thanks for the find. Commenting this out in our projects seems to have resolved the issue with no side effects. This was for apps with forced landscape, would still need to test in different scenarios.

@MrEsquire I edited SplashScreen.mm directly in xCode.

//_canRotateToLandscapeRight = false; // FIXME: check on iPad

 

I checked the code for 4.6.9 Unity and found no comments.

Code (CSharp):

1. - (void)updateOrientation:(ScreenOrientation)orient
2. {
3.     bool orientPortrait  = (orient == portrait || orient == portraitUpsideDown);
4.     bool orientLandscape = (orient == landscapeLeft || orient == landscapeRight);
5.  
6.     bool rotateToPortrait  = _canRotateToPortrait || _canRotateToPortraitUpsideDown;
7.     bool rotateToLandscape = _canRotateToLandscapeLeft || _canRotateToLandscapeRight;

Is this something? The good news is that we dont maybe need to wait for patch and if developers provide hotfix manually edit..

EDIT: I also can confirm that the splash screen is upside down and wrong orientation also.
Upgraded to iOS 9.1 and tested on iPhone 4s and iPhone 6. Initially thought was just iPhone 6 + issue. I'm pretty sure some Xcode needs tweaking.

Can a developer respond please!

 

BUMP.. still need urgent fix...annoys me that this is low priority!

 

If the above edits are not applicable for you, have you tried disabling "Use Animated AutoRotation" in the player settings? Not ideal, but if it's blocking you from releasing, worth the compromise I'd imagine.

 

Thanks dude for the idea, tried it and made no difference..iPad Mini original one no issue present, iPhone 6, issue is there. So its not restricted to all devices..

 

@MrEsquire I should have mentioned that we are using Unity 5.2.1p4 w/ xCode 7.0

We also saw after testing yesterday that this fixed this issue on iOS8 iPad3, but it introduced a weird squish/flicker at the start of the splash screen on iOS9 iPad Air2.

 

Same issue here! Can't publish game updates because of this problem...

 

anyone filed bug reports? not sure whats going on usually developers monitor this forum

 

@povillas can you provide the final splashscreen.mm for using it, until the next patch release is online?

 

Did this make it in to 5.2.2p2? I don't see its mention in the release notes. Did I just miss it? This is blocking our release.

 

I did a build with 5.2.2p2 and from xcode I opened SplashScreen.mm and it contains TODOS, FIXES comments as it was doing 5.2.2.p1.... I think this patch not fixing Splah Screen problems?

 

Its not in this patch release, we still need to wait but not sure till when!

 

ok... keep waiting

 

Related thread with additional info. Still waiting for the patch. http://forum.unity3d.com/threads/unity-5-2-0p1-ios-launch-image-wrong-size.356670/page-2

 

for me with 5.2.2p3 is still not working...

 

Same issue here. 5.2.2p3 didn't fixed the problem (at least for the iPhone 6 Plus).
As a workaround, I am commenting out the next lines from `SplashScreen.mm`:

Code (CSharp):

1.  
2. // launch screens always use landscapeLeft in landscape
3. //    if (isIphone && _usesLaunchscreen && _canRotateToLandscapeLeft)
4. //        _canRotateToLandscapeRight = false;
5.  

Do somebody have any other suggestions?

 

Same on my iPads. Games all start upside down, so can't issue any updates to my stuff for IOS. It's been broken since 5.1 so come on Unity pull your finger out please. Such an obvious bug surely proves there is no IOS testing going on prior to releasing patches.

 

Exactly that - NO TESTING. Not even talking about patch, what about main releases...
I sent mail to one of the developers..I'm annoyed at whats happened and the fact that this is a SHOW STOPPER issue, cannot release my games without this fix...and have to wait two weeks for this patch and when finally out does not work..Annoys me why this is not being fixed in the mean time we have features for iOS9.1 that no one is using yet being developed..its strange how we dont see QA in forums now, attitude stinks, yet they keep trying produce fancy figures of how many things get fixed all the time!

 

It's not just the splash screen but the whole app that's upside down. If you shake the iPad it then rotates to the correct way up.

 

I've just installed 5.2.2P3 and it fixes the IOS orientation problem on my devices. Just for reference it was an iPad Air 1 with IOS 8.4.1

 

On some devices -> well if you read the threads you know clearly told you to test on Iphone 6, iOS 9.1
Why was it so hard, of course Im going to give you negative feedback as the way this issue is being handled at such a slow pace..

But on positive side, you managed to reproduce it and now you can see that the issue does indeed exist.
Just one more problem left now- see other thread..

 

Funny case - if I Change the order of Landscape settings in my projects plist so that (left home button) is first - the splash screen starts in correct orientation. Unfortunately during engine initialization orientation is set back to upside down and then animates back to the correct rotation. Unity 4.6.9 on iPhone 5 with iOS 9.1.
