Emile khattar commented on CB-330:
----------------------------------
@edgar, if you read the code of the plugin you will see that logically no data
should be lost at all.
// onAppTerminate is fired on UIApplicationWillTerminateNotification
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(onAppTerminate) name:UIApplicationWillTerminateNotification
object:nil];
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/applicationWillTerminate:
This method lets your application know that it is about to be terminated and
purged from memory entirely. You should use this method to perform any final
clean-up tasks for your application, such as freeing shared resources, saving
user data, invalidating timers, and storing enough application state to
reconstitute your application’s interface when it is relaunched. Your
implementation of this method has approximately five seconds to perform any
tasks and return. If the method does not return before time expires, the system
may kill the process altogether.
five seconds should be enough i think
So in theory this fixed should be good to support people who are using
localStorage and Sql storage.
And the problem i had should be to the error i did by placing the plugin call
in the wrong place.
However i agree with you having some sort of a "natural" persistent storage
thanks everyone

> Dear Dev
> WebKit data (localstorage or local SQLite) are now stored in Library/ Caches
> folder (instead of Library/WebKit folder). This is a big problem for all apps
> using UIWebView and storing user data, because they will no longer be backed
> up and may be deleted. There are a lot of apps using localstorage or SQLite
> as a critical feature.
> The SQLite database gets deleted because the database is saved in a location
> on the filesystem which Apple does not consider to contain persistent data.
> *Steps to Reproduce:*
> In a UIWebView, create a new DB or use localStorage with JavaScript.
> You can see that the WebKit data is now stored in Library/Caches :
> *Expected Results:*
> We should at least specify the directory of WebKit data (and to set it
> to Documents/ for critical data)
> *Actual Results:*
> The WebKit data are stored in Library/Caches folder, and can be
> deleted
> *Regression:*
> To migrate database location from Library/Caches to some other location such
> as Documents.
