Subject [jira] [Commented] (CB-6843) iOS cordova app crashes on stringByEvaluatingJavaScriptFromString: in the class CDVCommandDelegateImpl.m.

    [ https://issues.apache.org/jira/browse/CB-6843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15430242#comment-15430242

Shazron Abdullah commented on CB-6843:
--------------------------------------

Looks like this is the line: https://github.com/apache/cordova-ios/blob/ebbc6d05995e50312c044dd1ae11d18e1ff669ba/CordovaLib/Classes/CDVCommandDelegateImpl.m#L74

Although, I'm afraid we won't be doing any fixes on 3.x anymore, so any fix that is available
in the future you would have to patch yourself. 
The exception appears to be in Apple code, so I'm not sure what's going on here.

Put this anywhere in your code:

#define CDV_ENABLE_EXEC_LOGGING 1

This should output in the Xcode console log what the JS is (although up to 160 characters
only).

> The app is been developed using the Cordova version 3.2 and with iOS versions  6 and
7. 
> In the app APNS is been supported, so in order to support the APNS feature we have to
sent the status to server when the app goes to the foreground . For this support we requested
the OS to extend the execution time () so that app can send the status to the server. In mean
time if the app rest a while in the background and comes to the foreground let say some 30
mins or one hour ,the app crashes out with exception EXC_BAD_ACCESS. 
> The crash report says that the exception is been caught in the CDVCommandDelegaetImpl
class in the method  evalJsHelper2: for the API i.e stringByEvaluatingJavaScriptFromString:.
