I have iPhone 4 (running iOS 6.0.1) and XCode 4.5.1 using Unity3d 3.5.6. I also get 90+ warnings (Semantic Issue: Empty parentheses interpreted as a function declaration), but everything works fine for me. It also used to work fine with iOS 6 (not 6.0.1).
It’s possible. We use render textures and camera order as well so that could be a problem as well… bizarre since it was working fine in older xcode/ios. I will report back if I can fix it and why. Welcome more comments on the issue as well (including the bizarre warnings).
We used Unity 3.5.6 and xCode 4.5.1 and IOS6 and the resulting app worked fine. After we ported the project to Unity 4 (xCode and IOS the same versions) the app shows the splash screen and then the app. But after quitting and restarting the app we have the same black screen issue: First splash screen and then black. We thought it would be a Unity 4 issue…
Any other idea that could cause / fix that issue?
