应用程序的 Objective-C Facebook 视频共享

Question

我对 Objective-c 非常陌生。基本上，我现在看到的都是黑色的。我被指派为我们正在制作的应用程序的 facebook 共享部分编写代码，相信我，我已经尝试了几乎所有的教程（没有一个有效，我已经尝试过）并在堆栈中解决了这里的问题，我仍然无法上传。所以请有人帮忙吗？

如何通过应用程序将视频上​​传到 Facebook？如果有，请提供示例代码。

这是我现在正在尝试的代码：

-(void)post
{
    NSURL *videourl = [NSURL URLWithString:@"https://graph.facebook.com/me/videos"];

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Here's to the Crazy Ones" ofType:@"mp4"];
    NSURL *pathURL = [[NSURL alloc]initFileURLWithPath:filePath isDirectory:NO];
    NSData *videoData = [NSData dataWithContentsOfFile:filePath];

    NSLog(@"PATH: %@", filePath);

    NSDictionary *params = @{
                             @"title": @"uploading",
                             @"description": @"testing..."
                             };

    NSLog(@"uploading...");

    SLRequest *uploadRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                  requestMethod:SLRequestMethodPOST
                                                            URL:videourl
                                                     parameters:params];
    [uploadRequest addMultipartData:videoData
                           withName:@"source"
                               type:@"video/quicktime"
                           filename:[pathURL absoluteString]];
    NSLog(@"Here it goes...");
    uploadRequest.account = self.facebookAccount;
    NSLog(@"Past uploadrequest...");
    [FBSession setActiveSession:FBSession.activeSession];
    [uploadRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
        NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
       // [FBSession setActiveSession:FBSession.activeSession];
        if (!FBSession.activeSession.isOpen) {
         //   [FBSession openActiveSessionWithAllowLoginUI: YES];
            [FBSession setActiveSession:FBSession.activeSession];
        }

        NSLog(@"response string: %@", responseString);
        NSLog(@"Here I am...");
        if(error){
            NSLog(@"Error %@", error.localizedDescription);
        }else
            NSLog(@"%@", responseString);
    }];
}

这样我得到一个错误：

{"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}
