如何在facebook SDK中分享视频？

Question

我编写了如下代码，其中文件存在于资源中。 它不是空的。

我成功添加图像，但坚持视频。

-(void)uploadVideo {

    NSLog(@"UPload Videio ");

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"abc" ofType:@"mp4"];

    NSError *error = nil;


    NSData *data = [NSData dataWithContentsOfFile:filePath options:NSDataReadingUncached error:&error];

    if(data == nil && error!=nil) {
        //Print error description

        NSLog(@"error is %@", [error description]);
    }

    NSLog(@"data is %@", data);

    NSDictionary *parameters = [NSDictionary dictionaryWithObject:data forKey:@"sample.mov"];

    if (FBSession.activeSession.isOpen) {


        [FBRequestConnection startWithGraphPath:@"me/videos"
                                     parameters:parameters
                                     HTTPMethod:@"POST"
                              completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                //  [FBRequestConnection setVideoMode:NO];

                                  if(!error) {
                                      NSLog(@"OK: %@", result);
                                  } else
                                      NSLog(@"Error: %@", error.localizedDescription);

                              }];

    } else {

        // We don't have an active session in this app, so lets open a new
        // facebook session with the appropriate permissions!

        // Firstly, construct a permission array.
        // you can find more "permissions strings" at http://developers.facebook.com/docs/authentication/permissions/
        // In this example, we will just request a publish_stream which is required to publish status or photos.

        NSArray *permissions = [[NSArray alloc] initWithObjects:
                                @"publish_stream",
                                nil];
        //[self controlStatusUsable:NO];
        // OPEN Session!
        [FBSession openActiveSessionWithPermissions:permissions
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState status,
                                                      NSError *error) {
                                      // if login fails for any reason, we alert
                                      if (error) {

                                          // show error to user.

                                      } else if (FB_ISSESSIONOPENWITHSTATE(status)) {

                                          // no error, so we proceed with requesting user details of current facebook session.


                                          [FBRequestConnection startWithGraphPath:@"me/videos"
                                                                       parameters:parameters
                                                                       HTTPMethod:@"POST"
                                                                completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                                                    //  [FBRequestConnection setVideoMode:NO];

                                                                    if(!error) {
                                                                        NSLog(@"Result: %@", result);
                                                                    } else
                                                                        NSLog(@"ERROR: %@", error.localizedDescription);

                                                                }];





                                          //[self promptUserWithAccountNameForUploadPhoto];
                                      }
                                      // [self controlStatusUsable:YES];
                                  }];
    }

}

作为回报，我得到错误

如何使用facebook iOS SDK将视频上传到Facebook？

谢谢

Answer 1

这是将视频上传到Facebook的方法。 此代码正在测试并100％正常运行。

ACAccountStore *accountStore = [[ACAccountStore alloc] init];

ACAccountType *facebookAccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

// Specify App ID and permissions
NSDictionary *options = @{ACFacebookAppIdKey: FACEBOOK_ID,
                          ACFacebookPermissionsKey: @[@"publish_stream", @"video_upload"],
                          ACFacebookAudienceKey: ACFacebookAudienceFriends}; // basic read permissions

[accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *e) {
    if (granted) {
        NSArray *accountsArray = [accountStore accountsWithAccountType:facebookAccountType];

        if ([accountsArray count] > 0) {
            ACAccount *facebookAccount = [accountsArray objectAtIndex:0];


            NSDictionary *parameters = @{@"description": aMessage};


            SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                            requestMethod:SLRequestMethodPOST
                                                                      URL:[NSURL URLWithString:@"https://graph.facebook.com/me/videos"]

            [facebookRequest addMultipartData: aVideo
                                     withName:@"source"

建议：

我认为这可能是一个权限问题，但我不确定抛出错误的位置。 将抛出的委托方法未显示在您的代码中。 我认为将您的代码与此示例中的步骤进行协调可能会有所帮助; 如果是的话请接受答案。

样本的一些关键方面：

权限：

- (IBAction)buttonClicked:(id)sender {
    NSArray* permissions = [[NSArray alloc] initWithObjects:
                            @"publish_stream", nil];
    [facebook authorize:permissions delegate:self];
    [permissions release];
}

构建请求：

- (void)fbDidLogin {
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"mov"];
    NSData *videoData = [NSData dataWithContentsOfFile:filePath];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, @"video.mov",
                                   @"video/quicktime", @"contentType",
                                   @"Video Test Title", @"title",
                                   @"Video Test Description", @"description",
                       nil];
    [facebook requestWithGraphPath:@"me/videos"
                         andParams:params
                     andHttpMethod:@"POST"
                       andDelegate:self];
}

请求didLoad委托方法：

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]) {
        result = [result objectAtIndex:0];
    }
    NSLog(@"Result of API call: %@", result);
}

请求didFail委托方法：

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error {
    NSLog(@"Failed with error: %@", [error localizedDescription]);
}

此代码在FaceBook SDK 3.14.1上成功测试

建议：在.plist中

设置FacebookAppID，FacebookDisplayName，
URL类型 - >项目0-> URL方案设置为带有fb facebookappId前缀

-(void)shareOnFaceBook

    //you can use dataWithContentsOfURL if you have a Url of video file
    //NSData *videoData = [NSData dataWithContentsOfURL:shareURL];
    //NSLog(@"data is :%@",videoData);
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               videoData, @"video.mov",
                               @"video/quicktime", @"contentType",

        }
}

我GOT错误：

 The operation couldn’t be completed. (com.facebook.sdk error 5.)

它发生在Facebook正在进行时。 下次我打开我的应用程序，它工作正常，它始终是第一次。 在应用程序中尝试了一切，但它似乎在Facebook SDK方面。

看到com.facebook.sdk error 5原因很少：

• 会话未公开。 验证。
• Facebook已检测到您正在向系统发送垃圾邮件。 更改视频名称。
• Facebook使用SDK有一个定义的限制。 尝试使用其他应用。

您之前是否要求获得publish_stream权限？
