Reading Apple doc (http://developer.apple.com/library/mac/#releasenotes/DataManagement/RN-CoreData/_index.html), I’ve noticed the following about NSConfinementConcurrencyType:
bq. You cannot use this concurrency type in conjunction with the new nested contexts feature
But in Chapter 5 (Parent/Child NSManagedObjectContext Instances), PPRImportOperationAlt1 class, you do the following:
NSManagedObjectContext *localMOC = nil; NSUInteger type = NSConfinementConcurrencyType; localMOC = [[NSManagedObjectContext alloc] initWithConcurrencyType:type]; [localMOC setParentContext:[self mainContext]];
Is this ok?
Thank you in advance.
