I'm wondering how to add the @synthesize statements for the MovieEditorViewController header file in XCode

The implementation file looks like this:

#import "MovieViewController.h"
#import "Movie.h"
#import "MovieEditorViewController.h"

@implementation MovieViewController

@synthesize titleLabel;
@synthesize boxOfficeGrossLabel;
@synthesize summaryLabel;
@synthesize movie;

but i'm thinking my problem is not adding @synthesize statements for the MovieEditorViewController header file. If it's not this then I've included the debugging log below.

I'm really new to programming and I really can't seem to figure out whats going wrong. When I run the iOS simulator and click the button to display editable text fields the program terminates and goes back to the homescreen. The debugger shows as follows:

If anyone could point me in the right direction i'd be very grateful...

Thanks!

Looks like you're in the iPhone SDK Development book. Have you made it to section 4.8 yet? The error says that your MovieViewController doesn't have a property named editingViewController, which is something you add in 4.8. The project won't build and run until you get through section 4.9, which is where you make some connections.
