Sean commented on CB-330:
-------------------------

@Davide I really like your idea of just changing the location of where data is saved. I added your code as the block that runs when didFinishLaunchingWithOptions runs but I get a compile error I think you might understand. I've never worked with this language so fixing it is not obvious to me.

NSString *localStorageSubdir = (IsAtLeastiOSVersion(@"5.1")) ? @"Caches" : @"WebKit/LocalStorage";

The error I get is:

Undefined symbols for architecture armv6:
  "_IsAtLeastiOSVersion", referenced from:
      -[AppDelegate application:didFinishLaunchingWithOptions:] in AppDelegate.o
ld: symbol(s) not found for architecture armv6
clang: error: linker command failed with exit code 1 (use -v to see invocation)


Any help you, or anyone, can send my way is greatly appreciated.

> 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.
