Question

我一直在尝试使用FBSDKGraphRequest上传带有标题和标记好友的照片，但我真的很难让标签发挥作用。这就是我得到的：

NSDictionary *parameters = @{
                             @"caption" : message,
                             @"picture" : UIImagePNGRepresentation(image),
                             @"tags"    : @[@{@"tag_uid": @902893713061742, @"x":@0.0, @"y":@0.0},
                                            @{@"tag_uid": @902486513129784, @"x":@10.0, @"y":@10.0}],
                             };

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me/photos" parameters:parameters tokenString:token.tokenString version:@"v2.3" HTTPMethod:@"POST"];
[connection addRequest:request completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
    if(error)
        NSLog(@"%@", error);
    else
        NSLog(@"Success");
}];
[connection start];

但每次我尝试运行它都会抛出此错误：

FBSDKLog：不支持的FBSDKGraphRequest附件:(
          {
          ＆＃34; tag_uid＆＃34; = 902893713061742;
          x = 0;
          y = 0;
      }，
          {
          ＆＃34; tag_uid＆＃34; = 902486513129784;
          x = 10;
          y = 10;
      }
  ），跳过。

我已经尝试了几种不同的方法来附加@＆＃34;标签＆＃34;信息但他们都没有完成这项工作。有谁知道这样做的正确方法？这甚至可能吗？ https://developers.facebook.com/docs/graph-api/reference/user/photos/让我这么认为。

编辑：尝试发布没有标签，然后用它们更新帖子ID，但仍然没有成功:(

您无法使用相同的FBSDKGraphRequest上传带有标题和标记好友的照片。您必须为不同的任务调用不同的方法，如下所示：

对于标题和标签之类的消息：

if ([FBSDKAccessToken currentAccessToken]){
 NSDictionary *params = @{
                        @"message": @"This is a test message",
                       };
    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/feed" parameters:params HTTPMethod:@"POST"]startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
        if (error)
         NSLog(@"error:%@", error);
        else{
            UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"FBSDKGraphRequest" message:@"Text Shared successfully..!" delegate:self cancelButtonTitle:@"Done" otherButtonTitles:nil, nil];
            [av show];
            }
 }];
}

发布照片：

if ([FBSDKAccessToken currentAccessToken]){
NSDictionary *params = @{@"sourceImage":UIImagePNGRepresentation(pickedImage)};
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
    if (!error) {
        UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"FBSDKGraphRequest" message:@"Image Shared successfully..!" delegate:self cancelButtonTitle:@"Done" otherButtonTitles:nil, nil];
        [av show];
    } else {
        NSLog(@"Graph API Error: %@", [error description]);
    }
  }];
}

希望能帮到你...... :)。

您可以上传带有标题的照片，只需将“标题”键更改为“消息”

if FBSDKAccessToken.currentAccessToken().hasGranted("publish_actions") {
     let params: [NSObject : AnyObject] = ["message": "Caption", "sourceImage" : UIImagePNGRepresentation(image)]
     FBSDKGraphRequest(graphPath: "me/photos", parameters: params, HTTPMethod: "POST").startWithCompletionHandler({ (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
            // Handle result
     })
}

以下是帮助您入门的基本代码：

if (![FBSDKAccessToken currentAccessToken]) {
            [self alertWithMessage:@"Log into FB and request publish_actions" title:@"Upload Failed"];
            return;
        }
NSDictionary *params = @{@"source":UIImagePNGRepresentation([UIImage imageNamed:@"snoopy.png"])};

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
            if (!error) {
                [self alertWithMessage:[NSString stringWithFormat:@"Result: %@", result] title:@"Post Photo Success!"];
            } else {
                NSLog(@"Graph API Error: %@", [error description]);
            }
        }];

这保证会有效，因为我自己测试了它。请记住检查您拥有的访问令牌是否具有publish_actions权限，因为这可能也会影响您是否可以上传人们的图片。
