---------------------------------
Summary: [iOS]: View controller not properly unregistered in
CDVURLProtocol
Key: CB-1694
URL: https://issues.apache.org/jira/browse/CB-1694
Project: Apache Cordova
Issue Type: Bug
Components: iOS
Affects Versions: 2.2.0
Environment: Xcode 4.5 / OS X 10.7.5 (Lion) / Commit
b74752f42da53532150d17aab80c0c6ae36a1a69
Reporter: Kevin Hawkins

[CDVURLProtocol unregisterViewController:] does not properly unregister the
Cordova view controller from gRegisteredControllers. The view controller is
registered in gRegisteredControllers with its "long long" representation, but
it's unregistered by attempting to remove the view controller object itself
from the list, which of course is not in the set.
This causes a crash (EXC_BAD_ACCESS) in my test app (which removes and
re-creates the view controller through a plugin), because something seems to
call /!gap_exec again after my view controller has been deallocated. I'm not
sure if that points to a bigger problem or not. But at any rate, when I change
[CDVURLProtocol unregisterViewController:] to properly remove the view
controller from the set, my app never crashes, through multiple recycles of the
view controller.
I can attach my sample app, if that's helpful to understanding the crash
scenario. But the unregister bug is unambiguous, so we could just fix that.
