CoreData: error: Failed to call designated initializer on NSManagedObject class

Question

I have a little damn problem with CoreData. I want to insert a new Object, so I first have to create one. This is done by that code:

Challenges *newChallenge         


        

Answer 1

In case you ask yourself "OK, so how to I get that entity?" (like I did), you do this by using the entityForName method like so:

NSEntityDescription *entity = [NSEntityDescription entityForName:@"Challenges" inManagedObjectContext:self.managedObjectContext];

Challenges *newChallenge = [[Challenge alloc] initWithEntity:entity insertIntoManagedObjectContext:self.managedObjectContext];

Hope this helps, this thread has helped me a lot!
