---------------------------------

             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
            Assignee: Shazron Abdullah


[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.
