[jira] [Comment Edited] (CB-821) Cordova crashes with
EXEC_BAD_ACCESS when using camera on iOS 5.1.1
[ https://issues.apache.org/jira/browse/CB-821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13422367#comment-13422367 ]

---------------------------------------------------------
Picked up a similar issue from the Phonegap support forums where an iPad encountered the same error (EXEC_BAD_ACCESS on a similar line) after calling captureVideo() several times. This was still not fixed as of 1.9.0 (and possibly 2.0.0 as well). It was not reproducible on iOS 5.1.1 on the iPod Touch.
I'll ask them to post their error logs here if needed.

> I have a test page with a text box and a button which calls navigator.camera.getPicture(). To reproduce this issue:
> Browse to page, enter some text in the text box, tap the button to launch the camera, cancel the camera, enter some more text in the text box, tap button to launch camera again and then Cordova crashes out with EXEC_BAD_ACCESS.
> I'm not an iOS developer or proficient Xcode user, with that in mind, here is what Xcode tells me:
> This happens in Thread 11: com.apple.camera.avcapturesession and this is what is shown (the EXEC_BAD_ACCESS is thrown on line starting with 0x35c1725a):
