libc++abi.dylib: terminate called throwing an exception
Found this link from Stackoverflow.com which describes something similar to what I am experiencing, which only happens to iOS 6 Game Center for Apps only supporting Landscape display. Delete the app and download from App Store again and test with Game Center logged in, and it works without problem. Problem identified!
Urh, hang on, I thought I fixed the problem in previous release already??!! Further investigation shows I missed something in my last release. And as my 3GS always has Game Center logged in, that's why it wasn't picked up during pre-release testing, damn! Definitely have to add this testing next time.
The fix is easy, before, the setup looks like this:
Just need to click on the 2 "Portrait" and "Upside Down" icons in "Supported Interface Orientations" and that fixed the problem. The setup now looks like this:
Issue fixed. Lucky the App Store still available before 20th December, hope there's not too many apps waiting for review and can still get reviewed before Christmas with the normal 7-8 days waiting time, fingers crossed...
