Subject [jira] [Commented] (CB-391) navigator.camera.getPicture() crashing on iOS after memory warning
Date Tue, 03 Apr 2012 00:55:23 GMT

    [ https://issues.apache.org/jira/browse/CB-391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13244881#comment-13244881

Shazron Abdullah commented on CB-391:
-------------------------------------

Following your steps, found the crash: https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVCamera.m#L156
(self.pickerController is nil at this point)

self.pickerController is nil at this point because CDVCamera's dealloc method was called.
CDVCamera's dealloc method was called because all the objects in CDVViewController's pluginObjects
property (a NSArray) are being purged because of the [super didReceiveMemoryWarning] call.
Mystery solved, fix still unknown...

> 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.
