How can I associate an NSManagedObject to the context after it has been initialised?

core-data, iphone, objective-c

Solution

This approach would be perfectly valid...

Items *item = [[Item alloc] initWithEntity:entity insertIntoManagedObjectContext:nil];
item.first = @"blah";
item.second = @"blah blah";

You're then free to pass this object around to where its needed and when you're ready to commit it to a managed object context, simply insert it and save.

[managedObjectContext insertObject:item];
NSError *error = nil;
[managedObjectContext save:&error];

Problem

For example, if I have an `NSManagedObject` named `Items`, and I want to set the `ManagedObjectContext` later (not when initialised), how would I do that? At the moment I'm doing this: ``` Items *item = [NSEntityDescription insertNewObjectForEntityForName:@"Items" inManagedObjectContext:_context]; ``` That automatically associates it to `_context`. But what if I want to do this: ``` Items *item = [[Items alloc] init]; item.first = @"bla"; item.second = @"bla bla"; ``` And I would want to pass that object to another method which would then associate it with the context and save it. So is there any way to just do a simple `item.managedObjectContext = _context` or something like that?
