iOS Upload embedded video from app to facebook

[newtoiphonesdk]

I am using this tutorial, but having problems. This is going in a viewController that has a webview in it. The viewController is pushed from a Table View that lists all video files in app. When the row of the Table View is selected, it stores the path to a NSString, and then passes that to the viewController and pushes to that view. The video loads fine and plays, but I am trying to get it to where I can upload the video to facebook. I have the facebook app all set up, but am running into problems, or don't understand the tutorial well. Here is my viewController (the one that plays the movie in a webview)'s .h:

#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#import "Facebook.h"
@interface ArchiveMovieViewController : UIViewController <UINavigationControllerDelegate,FBSessionDelegate, FBRequestDelegate>{
    NSString *selectedCountry;
    IBOutlet UIWebView *webview;
    Facebook *facebook;
}
-(IBAction)share;
-(void)facebookbutton;
@property (nonatomic, retain) NSString *selectedCountry;
@property (nonatomic, retain) Facebook *facebook;

@end

Here is the .m

#import "ArchiveMovieViewController.h"
#import "Facebook.h"

@implementation ArchiveMovieViewController
@synthesize selectedCountry, facebook;


- (void)viewDidLoad
{
    facebook = [[Facebook alloc] initWithAppId:@"358786560836750" andDelegate:self];
}
-(IBAction) share {
    [self facebookbutton];
}
- (void) facebookbutton {
    NSArray* permissions = [[NSArray alloc] initWithObjects:
                            @"publish_stream", nil];
    [facebook authorize:permissions];
    [permissions release];
}
- (void)fbDidLogin {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [paths objectAtIndex:0];
    
    NSString *proud = [[documentsDirectoryPath stringByAppendingPathComponent:@"archives"] stringByAppendingPathComponent:selectedCountry];
    
    NSString *content = [proud stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
    NSData *videoData = [NSData dataWithContentsOfFile:content];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, selectedCountry,
                                   @"video/quicktime", @"contentType",
                                   @"Video Test Title", @"title",
                                   @"Video Test Description", @"description",
                                   nil];
    [facebook requestWithGraphPath:@"me/videos"
                         andParams:params
                     andHttpMethod:@"POST"
                       andDelegate:self];
}
- (void)viewWillAppear:(BOOL)animated
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [paths objectAtIndex:0];
    
    NSString *proud = [[documentsDirectoryPath stringByAppendingPathComponent:@"archives"] stringByAppendingPathComponent:selectedCountry];
    
    NSString *content = [proud stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];    
    NSURL *url = [NSURL URLWithString:content];   
    [webview loadRequest:[NSURLRequest requestWithURL:url]];

}
-(void)fbDidNotLogin:(BOOL)cancelled {
	NSLog(@"did not login");
}
- (void)request:(FBRequest *)request didLoad:(id)result {
	if ([result isKindOfClass:[NSArray class]]) {
		result = [result objectAtIndex:0];
	}
	NSLog(@"Result of API call: %@", result);
}
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error {
    NSLog(@"Failed with error: %@", [error localizedDescription]);
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    
}

-(void) dealloc {
    [selectedCountry release];
    [facebook release];
    [super dealloc];
}
@end

In my appDelegate.m file, I added:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return [[_viewController facebook] handleOpenURL:url];
}

but, it gave me error:

unknown receiver _viewController, did you mean UIViewController?

When I click the button that I want to upload to Facebook, it goes to the Facebook app, has me login, I click Okay for the permissions, and it goes back to the app, but nothing happens in the app, and nothing gets uploaded. Any thoughts to what is going wrong?
