Subject [jira] [Commented] (CB-330) localStorage / SQLDatabase no longer persistent after iOS 5.01 Update
Date Wed, 21 Mar 2012 10:29:38 GMT


Daniel commented on CB-330:

I also have the armv6 as a target architecture (iPhone 3G) and adding this plugin to the project
gives me the following compilation error:

21-Mar-2012 10:32:48	     [exec]         Ld build/Release-iphoneos/ normal armv6
21-Mar-2012 10:32:48	     [exec] (1 failure)
21-Mar-2012 10:32:48	     [exec] Undefined symbols for architecture armv6:
21-Mar-2012 10:32:48	     [exec]   "_OBJC_CLASS_$_CDVLocalStorage", referenced from:
21-Mar-2012 10:32:48	     [exec]       objc-class-ref in AppDelegate.o
21-Mar-2012 10:32:48	     [exec] ld: symbol(s) not found for architecture armv6
21-Mar-2012 10:32:48	     [exec] collect2: ld returned 1 exit status

Would it be an idea to only link to this header file if iOS >= 5.1? In that case I would
expect the app to compile fine for older devices. (Since there will never be an iOS 5.1+ for
armv6/iPhone 3G)

iOS WebKit Database Locations.txt
> 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.
