how to create a NSManagedObject

I am currently reading my coredata like this

NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
                    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Manuz" inManagedObjectContext:__managedObjectContext];
                    [fetchRequest setEntity:entity];
                    NSArray *fetchedObjects = [__managedObjectContext executeFetchRequest:fetchRequest error:nil];
                    NSManagedObject *myinfo = [NSManagedObject alloc]
                    for (NSManagedObject *info in fetchedObjects) {
                        [self startTheParsingProcess:[info valueForKey:@"manu"]];
                    }

I am having some issues with my for statement, its execuing several time and I am not sure why its doing that.. and come to think of it I don't really need it..

I am hoping there is an alternative solution to this where I just initalize the NSManagedObject and then add it to the method call I do in that for statment...

So I guess something like this

NSManagedObject *info = [[NSManagedObject alloc] init]; //this is obviously wrong.. 
[self startTheParsingProcess:[info valueForKey:@"manu"]];

any help would be awesome!

Do not create a NSManagedObject using alloc & init. If you want to create an instance of an entity "Manuz", you would do so by inserting a new Manuz object into the managed object context.

NSManagedObject *newManuz = [NSEntityDescription insertNewObjectForEntityForName:@"Manuz" inManagedObjectContext:context];
