Subject [jira] [Commented] (CB-1558) LocalStorage is lost after upgrade to cordova 2.1 and ios6 up from from ios5
Date Fri, 28 Sep 2012 19:23:07 GMT

    [ https://issues.apache.org/jira/browse/CB-1558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13465840#comment-13465840

Christian Hemker commented on CB-1558:
--------------------------------------

This problem happens if you have created an App (the old Version of your app),
which stores the LocalStorage into the Default Location under iOS 5 <iOS App Directory>/Library/Caches/file__0.localstorage
There you have already the Problem with iOS 5.1.x, that the Caches Directory can be deleted,
when iOS is running out of space.

I had the same problem with the old version of my app with cordova 2.1 and iOS 6.
If you like, you can use this fix for that.

{code:title=CDVLocalStorage.m Line 69}

    // ////////// LOCALSTORAGE
    NSString* original;
    NSString* backup;
    
    if(IsAtLeastiOSVersion(@"5.1") && !IsAtLeastiOSVersion(@"6.0") ){
        // 5.1 <= running iOS Version < 6.0
        original = [[appLibraryFolder stringByAppendingPathComponent:@"Caches"]stringByAppendingPathComponent:@"file__0.localstorage"];
        NSLog(@"createBackupInfo iOS 5.1 original:%@", original);
        
        backup = [backupsFolder stringByAppendingPathComponent:@"localstorage.appdata.db"];
        NSLog(@"createBackupInfo iOS 5.1 backup:%@", backup);
    } else {
        // iOS Version >= 6.0
        original = [[appLibraryFolder stringByAppendingPathComponent:@"WebKit/LocalStorage"]
stringByAppendingPathComponent:@"file__0.localstorage"];
        NSLog(@"createBackupInfo iOS 6 original:%@", original);

        backup = [[appLibraryFolder stringByAppendingPathComponent:@"Caches"] stringByAppendingPathComponent:@"file__0.localstorage"];
        NSLog(@"createBackupInfo use Caches folder to save in WebKit directory backup:%@",
backup);
    }
    
    CDVBackupInfo* backupItem = [[CDVBackupInfo alloc] init];
    backupItem.backup = backup;
    backupItem.original = original;
    backupItem.label = @"localStorage database";

    [backupInfo addObject:backupItem];
{code}
