Magical Record Truncate not working after app terminate

问题

hey all i've code like this

if ([cellValue isEqualToString:@"Logout"])
    {

        NSManagedObjectContext *localContext = [NSManagedObjectContext MR_contextForCurrentThread];
        [EUserBrief MR_truncateAllInContext:localContext];
        [DownloadList MR_truncateAllInContext:localContext];    
    }

the code i want to truncate all data on entities [EUserbrief] and [DownloadList].. the code working fine, but after app terminate and i get in , EuserBrief data and downloadlist still there,,, any solution for this?

回答1:

You need to call

[localContext MR_save];

Your changes will not be persisted to any data store without saving.
