Richard Kimber commented on CB-391:
-----------------------------------
I ran into the same issue and fixed by using the solution suggested by Jonathan
Hobson: comment out [super didReceiveMemoryWarning] in
didReceiveMemoryWarning.
Here is the repo steps to hit this bug 100% on simulator:
1. Run your code in simulator, call up camera with
navigator.camera.getPicture() to open the album (since camera is not available
on simulator)
2. Simulator > Hardware > Simulate memory warning
3. Return from the iOS album (either click 'Cancel' or pick a photo)
4. Observe crash of the app
This is because the [super didReceiveMemoryWarning] see the web view is running
in background (while the album/camera is on) so released it. Later when the
album/camera closes and tries to call the JS callback, it cannot find the JS
handler and hence crash. Usually in object-c, it is ok to release background
views and reconstruct later, just for PhoneGap the web view could not be
removed as it is the root view and it has the JS callback to be used later.

> Key: CB-391
> URL: https://issues.apache.org/jira/browse/CB-391
> Project: Apache Callback
> Issue Type: Bug
> Components: iOS
> Affects Versions: 1.5.0
> Environment: 2 x iPhone 4S, iOS 5.1. Can't replicate on simulator or
> iHone 3GS with iOS 5.0.1
> Reporter: Richard Kimber
> Assignee: Shazron Abdullah
> Attachments: Wulvern_2012-03-27-141033_Richs-iPhone.crash
>
>
> getPicture has become very unstable on previously working code, affecting
> both Phonegap 1.4.1 and Cordova 1.5.0. Contributing factors, since last
> working build I have upgraded Xcode to 4.3.2 (from whatever the last version
> was) and iPhone to iOS 5.1 from 5.0.1.
> Memory warning is received on displaying camera, app crashes when you select
> 'use'. Restarting device usually resolves problem for a limited amount of
> time. Problem is intermittent and sometime difficult to replicate. Selecting
> from Photo library works fine.
> Options used:
> var options = {
> quality: 40,
> sourceType: Camera.DestinationType.FILE_URI
> };
> See
> https://groups.google.com/forum/?hl=en?hl%3Den&fromgroups#!topic/phonegap/ZLbw0s4JREs
> for more details.
> See attached for example crash log.
