Clearing CoreData and all that inside

Question

I\'m pretty new to CoreData and this app that uses it. And I\'m currently working on a feature that clears the entire core data when I log out in the app.

I have 2 sqlli

Answer 1

I use this function in the AppDelegate of one of my apps...

- (void)deleteAllCoreData
{
    NSPersistentStore *store = self.persistentStoreCoordinator.persistentStores[0];
    NSError *error;
    NSURL *storeURL = store.URL;
    NSPersistentStoreCoordinator *storeCoordinator = self.persistentStoreCoordinator;
    [storeCoordinator removePersistentStore:store error:&error];
    [[NSFileManager defaultManager] removeItemAtPath:storeURL.path error:&error];

    __persistentStoreCoordinator = nil;
    __managedObjectContext = nil;
    __managedObjectModel = nil;

    [self addDefaultData];
}

It deletes the persistent store that CoreData uses and leaves it so that a new one is set up when core data is accessed again.

This is the method described in the second link you provided.
