Question

I know how to post an image using the GRAPH API and I know how to post a comment using the same. But I can’t figure out how to post a photo and allow the user to also include a message/status with the photo (all posting on the user’s own wall).

This is the code that I am using to upload a photo from my app to user’s wall. The GRAPH API does not define what other keys I can specify in the param dictionary.

-(void) uploadPhotoToFacebook {
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   imageView.image, @"picture", nil];

    [facebook requestWithGraphPath:@"me/photos"
                     andParams:params
                 andHttpMethod:@"POST"
                   andDelegate:self];
}

I have found ways to do this using the now deprecated Facebook API but that doesn’t help me.

Thanks for the help,

// Post a status update along with picture via the Graph API, and display an alert view
with the results or an error.

NSString *message =  @"This is status Message!";
UIImage *image = [UIImage imageNamed:@"myPngImageToPost"];

NSDictionary *params = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:message, UIImagePNGRepresentation(image), nil] forKeys:[NSArray arrayWithObjects:@"message", @"picture", nil]];

// use the "startWith" helper static on FBRequest to both create and start a request, with
// a specified completion handler.
[FBRequest startWithGraphPath:@"me/photos"
                 parameters:params
                 HTTPMethod:@"POST"
          completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {

              [self showAlert:message result:result error:error];
          }];

The above code will show status update as well as image below your status message.
