如何在 facebook SDK 中分享视频？

Question

我在资源中存在文件的地方编写了如下代码。它不为空。

我成功添加了图片，但卡在了视频上。

-(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];
                                      }

如何使用 facebook iOS SDK 将视频上传到 facebook？

谢谢

Answer 1

这是一种将视频上传到 Facebook 的方法。此代码正在测试并且 100% 正常工作。

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"]
                                                               parameters:parameters];

            [facebookRequest addMultipartData: aVideo
                                     withName:@"source"
                                         type:@"video/mp4"
                                     filename:@"video.mov"];

            facebookRequest.account = facebookAccount;

                    NSLog(@"responedata:%@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
                }else{
                    NSLog(@"%@",error.description);
                }
            }];
        }
    } else {
        NSLog(@"Access Denied");
        NSLog(@"[%@]",[e localizedDescription]);
    }
}];

推荐：

我认为这可能是权限问题，但我不确定错误是在哪里引发的。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sample 中的步骤进行协调可能会有所帮助；如果是，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]);
}

此代码已在 FaceBook SDK 3.14.1 上成功测试

推荐：在.plist中

设置 FacebookAppID、FacebookDisplayName、
URL types->Item 0->URL Schemes 设置为带有 fb 前缀的 facebookappId

    NSData *videoData = [NSData dataWithContentsOfFile:filePathOfVideo];
    //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",
                               @"Video name ", @"name",
                               @"description of Video", @"description",

我遇到了错误：

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

在启动 facebook 时发生。下次我打开我的应用程序时，它运行良好，它总是第一次。尝试了应用程序中的所有内容，但似乎是在 Facebook SDK 方面。

看到com.facebook.sdk error 5的几个原因：

• 会话未打开。验证。
• Facebook 检测到您正在向系统发送垃圾邮件。更改视频名称。
• Facebook 对使用 SDK 有明确的限制。尝试其他应用。

您之前是否请求过publish_stream 权限？
