Question

我正在尝试为我的ios应用创建一个简单的共享功能。我想利用新的共享对话框（诸如标记朋友，添加地点，ecc等优点）。我想分享的是一张照片，一个指向itunes app下载的链接，一个来自ios应用程序的描述。我尝试过这样的共享方式：

NSURL *url=[[NSURL alloc] initWithString:@"https://itunes.apple.com/it/app/myapplication"];
[FBDialogs presentShareDialogWithLink:url name:@"My app name" caption:@"" description:@"prefilled descriptiontest" picture:[NSURL URLWithString:@"http://www.example.com/image.jpg"] clientState:nil handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
    if(error) {
        // An error occurred, we need to handle the error
        // See: https://developers.facebook.com/docs/ios/errors

        UIAlertView *av = [[[UIAlertView alloc]
                            initWithTitle:@"Sorry :("
                            message:@"There's been a problem publishing your message. Please try again!"
                            delegate:self
                            cancelButtonTitle:@"Close"
                            otherButtonTitles:nil] autorelease];
        [av show];

    } else {
        // Success

        UIAlertView *av = [[[UIAlertView alloc]
                            initWithTitle:@"Published!"
                            message:@"Your post has been successfully published."
                            delegate:self
                            cancelButtonTitle:@"Close"
                            otherButtonTitles:nil] autorelease];
        [av show];
    }
}];

它有效，但我只在分享对话框中看到我的预填充描述，当我在facebook上看到共享内容时，我只看到从链接页面中获取的描述。所以我尝试了另一个解决方案，即photodialog：

 UIImage *Image=[UIImage imageNamed:@"myphoto.jpg"];
// Open the image picker and set this class as the delegate
FBPhotoParams *params = [[FBPhotoParams alloc] init];

// Note that params.photos can be an array of images.  In this example
// we only use a single image, wrapped in an array.
params.photos = @[Image];



[FBDialogs presentShareDialogWithPhotoParams:params
                                 clientState:nil
                                     handler:^(FBAppCall *call,
                                               NSDictionary *results,
                                               NSError *error) {
                                         if (error) {
                                             NSLog(@"Error: %@",
                                                   error.description);
                                         } else {
                                             NSLog(@"Success!");
                                         }
                                     }];

通过这种方式，我可以在我的墙上发布照片，但描述参数似乎只是读取，我无法设置任何预填充文本。我该怎么办？有一种方法可以在sharelink对话框中强制显示我的描述文本吗？或者有一种在photodialog中设置文本的方法？还是有其他解决方案？

唯一的解决方案似乎是仅使用网络回退：

NSMutableDictionary *parameter = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               name, @"name",
                               author, @"caption",
                               linkShare, @"link",
                               userImage, @"picture",
                               nil];

[FBWebDialogs presentFeedDialogModallyWithSession:nil
                                   parameters:parameter
                                      handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                          if (error)
                                          {
                                              NSLog(@"Error publishing story: %@", error.description);
                                          }
                                          else
                                          {
                                              if (result == FBWebDialogResultDialogNotCompleted)
                                              {
                                                  NSLog(@"User cancelled.");
                                              }
                                              else
                                              {
                                                  NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
                                                  NSLog(@"User login");

                                                  if (![urlParams valueForKey:@"post_id"])
                                                  {
                                                      NSLog(@"User cancelled post.");

                                                  }
                                                  else
                                                  {
                                                      NSString *result = [NSString stringWithFormat: @"Posted story, id: %@", [urlParams valueForKey:@"post_id"]];
                                                      NSLog(@"result %@", result);

                                                  }
                                              }
                                          }
                                     }];

Fb分享对话框，我可以简单地发布带描述的图片吗？
