Re: [osg-users] iOS: integration with not-OpenGL apps
Hi Mike, thanks for the bug-report, I fixed the issue on the gtihub repository. I will submit a new version to osg.submission asap. I am not sure why your app crashes, perhaps you can enable NSZombies and get an idea, why this happens. cheers, Stepan Am 31.10.12 17:16, schrieb Mike Wozniewski: FYI, it looks like Stephan's FlipsideView example is broken in iOS 6.

Thank you Stefan, I'm going to try it right now...

Basically you create a WindowDataClass with your parent-view as parameter, this will instruct GraphicsWindowIOS to add the created view to this parent-view, and it does respect the sizes in the traits-object.

Re: [osg-users] iOS: integration with not-OpenGL apps
I've tried the new updated version and it works fine on my end. Now it looks very easy to manage the OSG's view within a custom view controller. I'd like to ask a couple of things, just to understand better how everything works. 1) in GraphicsWindowIOS, beyond the window and view, also a view controller is defined and it is allocated in GraphicsWindowIOS.mm just after the view...is this view controller really needed? How is it used? 2) in the view_test example, at the end of FlipsideViewController,mm file, what is the role of USE_GRAPICSWINDOW_IMPLEMENTATION(IOS) ? I tried by removing it and it looks like that my app still works... Thanks.
