如何使Facebook对话视图中的文本框变大,并显示应用程序摘要?

关于图片下方的文本,您可以查看iOS库提供的演示。例如,上传文本的部分可以在 this file

- (IBAction) publishStream: (id)sender {

  SBJSON *jsonWriter = [[SBJSON new] autorelease];

  NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                               @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil];

  NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
  NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                               @"a long run", @"name",
                               @"The Facebook Running app", @"caption",
                               @"it is fun", @"description",
                               @"http://itsti.me/", @"href", nil];
  NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
  NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 kAppId, @"api_key",
                                 @"Share on Facebook", @"user_message_prompt",
                                 actionLinksStr, @"action_links",
                                 attachmentStr, @"attachment",
                                 nil];


  [_facebook dialog: @"stream.publish"
          andParams: params
        andDelegate:self];

}

如果你想在这篇文章中添加一个图片,试试看

NSDictionary* media = [NSDictionary dictionaryWithObjectsAndKeys:
                           @"image", @"type",
                           @"your.image/url.png", @"src",
                           @"http://www.alink.org", @"href",
                           nil];

NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                   @"a long run", @"name",
                                   @"The Facebook Running app", @"caption",
                                   @"it is fun", @"description",
                                   [NSArray arrayWithObjects:media, nil ], @"media",
                                   @"http://itsti.me/", @"href", nil];
