Dewang Shah commented on CB-330:
--------------------------------
This issue seems to have returned after iOS 6. Looking at the code in
CDVLocalStorage, there is a check for the version to be < 6.0
NSString* original = [[appLibraryFolder stringByAppendingPathComponent
:
(IsAtLeastiOSVersion(@"5.1") && !IsAtLeastiOSVersion(@"6.0")) ?
@"Caches":@"WebKit/LocalStorage"]
stringByAppendingPathComponent:@"file__0.localstorage"];
As a result data for a new app on iOS 6 is now lost when the app is closed and
then restarted. Strangely enough the data is only lost on the first run. From
the second run onwards data is persisted.
> localStorage / SQLDatabase no longer persistent after iOS 5.01 Update

> 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.
