Using Facebook SDK 3.0:

 - (void)postPhotoThenOpenGraphAction {
    FBRequestConnection *connection = [[FBRequestConnection alloc] init];

    // First request uploads the photo.
    FBRequest *request1 = [FBRequest 
        requestForUploadPhoto:self.selectedPhoto];
    [connection addRequest:request1
        completionHandler:
        ^(FBRequestConnection *connection, id result, NSError *error) {
            if (!error) {
            }
        }
            batchEntryName:@"photopost"
    ];

    // Second request retrieves photo information for just-created 
    // photo so we can grab its source.
    FBRequest *request2 = [FBRequest 
        requestForGraphPath:@"{result=photopost:$.id}"];
    [connection addRequest:request2
         completionHandler:
        ^(FBRequestConnection *connection, id result, NSError *error) {
            if (!error &&
                result) {
                NSString *source = [result objectForKey:@"source"];
                [self postOpenGraphActionWithPhotoURL:source];
            }
        }
    ];

    [connection start];
}

They follow this post with an OpenGraph action publish ([self postOpenGraphActionWithPhotoURL:source];), but if you just want the image on the user's wall, you wont need that.

Yay!, FB SDK 3.0 rocks! No more AppDelegate.facebook :)
