Facebook 分享对话框不会发布带有本地图片的故事

Question

我正在尝试使用带有代码的共享对话框发布故事：

[FBDialogs presentShareDialogWithOpenGraphAction:action
                                      actionType:@"myApp:myActionType"
                             previewPropertyName:@"myObjectType"
                                         handler:^(FBAppCall *call, NSDictionary *results, NSError *error)
{
    if(error)
    {
        NSLog(@"Facebook: error publishing story: %@", error.description);
    }
    else
    {
        NSLog(@"Facebook: publishing story: result %@", results);
    }
}];

我得到共享对话框（显示图像预览）并按Post，然后我得到进度条但它没有进展，然后我切换回我的应用程序。不仅如此，处理程序不会被调用。我正在尝试使用本地生成的图像发布一个故事，如下所示：

id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
NSArray* image = @[ @{@"url": [UIImage imageNamed:@"image-poof-1.png"], @"user_generated": @"true"} ];
[action setObject:image forKey:@"image"];

id<FBGraphObject> object = [FBGraphObject openGraphObjectForPost];
[object setObject:@"myApp:myObjectType" forKey:@"type"];
[object setObject:@"my title" forKey:@"title"];
[object setObject:@"my description" forKey:@"description"];

[action setObject:object forKey:@"myObjectType"];

我尝试使用指向网络上的图片的链接进行发布，并且成功了。

我认为属性 url 仅用于图像 url 尝试发布文件：

    NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:2];
    UIImage *picture = [UIImage imageNamed:@"75x75.png"];
    FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture];
    [variables setObject:graph_file forKey:@"file"];
    [variables setObject:@"this is a test message: postPictureButtonPressed" forKey:@"message"];
    //the fbGraph object is smart enough to recognize the binary image data inside the FbGraphFile
    //object and treat that is such.....
    FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"117795728310/photos" withPostVars:variables];

我没有分享对话框发布本地图片的经验，但我已将本地图片发布到 Facebook，但没有分享对话框。并成功发布了图片和消息。我的代码是

NSString *message=@"your message";
UIImage *sendPic = [UIImage imageNamed:@"image.png"];
    NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
    [params setObject:message forKey:@"message"];
    [params setObject:UIImagePNGRepresentation(sendPic) forKey:@"picture"];
    //fbShreBtn.enabled = NO; //for not allowing multiple hits
    [FBSession setActiveSession:[self appDelegate].session];

    [FBRequestConnection startWithGraphPath:@"me/photos"
     parameters:params
     HTTPMethod:@"POST"
     completionHandler:^(FBRequestConnection *connection,
     id result,
     NSError *error)
     {
         NSLog(@"fb result : %@",result);
         if (error)
         {
             //showing an alert for failure
             NSLog(@"error : %@",error);
             UIAlertView *alertView = [[UIAlertView alloc]
                                       initWithTitle:@"Post Failed"
                                       message:error.localizedDescription
                                       delegate:nil
                                       cancelButtonTitle:@"OK"
                                       otherButtonTitles:nil];
             [alertView show];

         }
         else
         {
             //showing an alert for success
             UIAlertView *alertView = [[UIAlertView alloc]
                                       initWithTitle:@"Post success"
                                       message:@"Shared successfully"
                                       delegate:nil
                                       cancelButtonTitle:@"OK"
                                       otherButtonTitles:nil];
             [alertView show];

         }
         //fbShreBtn.enabled = YES;
     }];

它可能对你有用。谢谢。
