I’m using MagicalRecord to persist an managed object called “Me”. Here is the two methods I’m trying (the first method doesn’t persist the data but the second one does):

NSManagedObjectContext *localContext = [NSManagedObjectContext MR_contextForCurrentThread];
[Me MR_createInContext:localContext];
[localContext MR_save];

The above method does not persist the data but the below one does:

NSManagedObjectContext *localContext = [NSManagedObjectContext MR_contextForCurrentThread];
[Me MR_createInContext:localContext];
[localContext MR_saveNestedContexts];

Why is MR_save not working?

    From the comments:

    Refer to “Regarding MagicalRecord, what is the difference between the methods MR_saveNestedContexts and MR_save”. There is a good description between the two methods.

    As of version 2.0.8, if you want to make sure you persist your nested contexts to the store, use MR_saveNestedContexts. If you want to save up ONLY ONE parent, use MR_save. IF the parent happens to be the root/default context, MR_saveNestedContexts and MR_save do the same thing, which is to persist to store.
