iOS 5 and Xcode 5 NSInvalidUnarchiveOperationException

by redbarndan · in Torque 2D Professional · 05/07/2014 (12:58 pm) · 6 replies

After upgrading to Xcode 5 I'm getting the following error when trying to build an app for a device with iOS 5.

Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '* -[NSKeyedUnarchiver decodeInt32ForKey:]: value for key (GLKViewControllerPauseOnWillResignActiveCoderKey) is not an integer number'

The app runs fine on iOS 6 and 7 devices but crashes on iOS 5 with the above error. This was built with the Torque 2D 3.0 master branch.

Anyone know what's causing it or more importantly how to fix? I've searched the web for hours, nothing I can find seems to help.

Thanks

    Can you get this to crash in the simulator? I don't have any iOS 5 devices to test this on.

    Found these links:

    Usually native iOS errors like you posted will show up in Google searches, typically leading you straight to Stack Overflow posts. Check to see if any of their solutions work for you. If so, kindly create a GitHub issue for the T2D repo, linking to this bug report and the potential fix. Much thanks.

    Unfortunately it looks like iOS 5 simulators are no longer supported in Xcode 5.

    I've spent hours looking up links and following different suggestions, mostly from Stack Overflow. None of them have solved my problem yet. I was hesitant to go the no storyboard route as I'm not too sure what that entails but I guess I'll try that next.

    Color me frustrated then, because I want to debug this but I can't drop down to iOS 5 on my devices. Is there a way for me to simulate this? Would switching my deployment target still trigger this?

    It looks like my first problem was upgrading my OS to Mavericks. According to Apple the iOS 5 simulators are no longer supported due to significant changes in the underlying OS. Wish I would have read that before upgrading.

    Are you running Mavericks or an earlier OS? Apparently the iOS 5 simulators can be installed via Preferences->Downloads->Components in Xcode 5 on Mountain Lion.

    I'm still working on removing storyboards as per your first link.

    It seems Apple really doesn't feel that supporting iOS 5 is still necessary and I'm wondering if all this is even worth it. Based on my usage statistics iOS 5 accounts for all of 2% of my users.

    I found another potential solution. This one involves removing the GLKViewController and GLKView from the storyboard and replacing them with ViewController and View and setting the custom class properties of each to T2DViewController and T2DView respectively. This works, but I'm not what other consequences it has.
