重新启动iPhone应用程序模拟器后，已保存的数据将重置

Question

In my iphone app am creating some records and storing them into core data. Everything works fine. But when I restart the simulator, the data is gone and I have to insert it again.

I am pretty sure am saving the data to core data. The code looks like:

    WorkItem *myObject = (WorkItem *)[[NSManagedObject alloc] initWithEntity:[NSEntityDescription entityForName:@"WorkItem" inManagedObjectContext:self
                                                                          .managedObjectContext] insertIntoManagedObjectContext:self.managedObjectContext];



myObject.descriptionText = @"My description";
myObject.title = @"My Title.";
myObject.URL = @"URL";
myObject.state = @"myStatus1";
 myObject.priority = @"myPriority1";
if (![myObject.managedObjectContext save:&error]) { 

    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
    abort();
}   

Kindly let me know if am missing something

I would do these things:

Single step the code in debug mode to make sure you are writing without an error.

Grab something that can read an SQLLite db and open the database to make sure you are writing the data to it.

Make sure you are not creating a new database with every run of your application.
