I'm having a problem with Core Data. I have a table view viewcontroller1 that is populated from an array that is populated with data in my Core Data model. When a cell is selected, it does a push segue to viewcontroller2, where you can view the saved data. From there, I have button called "edit" that, when selected, does a modal segue to viewcontroller3 where you can edit that data. Here's the code I have for saving the edited data.
//editModel
[self.editModel setValue:self.editNameTextField.text forKey:@"name"];
[self.editModel setValue:self.editTextView.text forKey:@"text"];
[self.editModel setValue:[NSDate date] forKey:@"date"];
NSError *error;
if (![[self.delegate managedObjectContext] save:&error])
{
NSLog(@"Can't save the edit: %@", [error localizedDescription]);
}
if (self.delegate)
[self.delegate dismissEdit:self];
else
NSLog(@"There is no delegate");
However, whenever I try calling this, I get an NSLog: Can't save the edit: (null)
viewcontroller2 reflects the change; as does the table view in viewcontroller1. But, when I quit the iOS Simulator and run it again, I only get data previous to the editing process. Help?
Most likely the managed object context isn't being made available by the delegate. Rather than get it from the delegate, each managed object has a link to the managed object context that it is added to so you can do:
[self.editModel.managedObjectContext save:&error]
