    [self.navigationController dismissModalViewControllerAnimated:YES];
    }

Can Anyone help me how to post image to FB in iPad.

Thanks in Advance.

Assuming you are using the latest Facebook iOS SDK and that you've declared an instance of Facebook class called facebook:

Check for permissions first

- (void)setupFacebook
{
    NSString *accessToken = [[NSUserDefaults standardUserDefaults] stringForKey:@"FBAccessToken"];
    NSDate *tokenExpiryDate = [[NSUserDefaults standardUserDefaults] objectForKey:@"FBExpirationDate"];
    facebook.accessToken = accessToken;
    facebook.expirationDate = tokenExpiryDate;
    if ([facebook isSessionValid] == NO) 
    {
        NSLog(@"Not logged in yet. Let's do it!");
        NSArray *permissions = [NSArray arrayWithObjects:@"read_stream", @"offline_access", @"publish_stream", nil];
        [facebook authorize:permissions delegate:self];
    } else {
        NSLog (@"Already logged in and ready to roll.");
        [self uploadPhoto]
    }
}

Responses to the authentication request will be available via the delegate methods below. This is where you can save the accessToken and tokenExpiryDate into NSUserDefaults so login credentials are persisted.

-(void)fbDidLogin 
-(void)fbDidNotLogin:(BOOL)cancelled 

Once you are logged in and have the right permissions, it's ok to call this method

- (void)uploadPhoto
{
    UIImage *image = // Your image here
    NSString *graphPath = @"me/photos";
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:image, @"picture", "Test caption", "caption"];
    [facebook requestWithGraphPath:graphPath andParams:params andHttpMethod:@"POST" andDelegate:self];
}

Responses to the upload call will be available via the delegate methods below:

- (void)request:(FBRequest *)request bodyDataUploadProgress:(CGFloat)progress
- (void)request:(FBRequest *)request didLoad:(id)result
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error

Hope if helps. Rog
