使用 FBConnect 在 Facebook 上分享图像

Question

在上面搜索了 2 天后，我终于发布了我的代码。

应用说明：我正在通过 imagePicker 选择图像，编辑后我想在 Facebook 上分享。

问题：我可以在墙上发布文字但不能在墙上发布图片，因为我没有任何 URL，我无法找到另一种在墙上发布图片的方式。

这是我的 PostToWall 的代码（我从另一个应用程序中窃取的）

FBStreamDialog* dialog = [[[FBStreamDialog alloc] init] autorelease];
dialog.userMessagePrompt = @"Enter your message:";
dialog.actionLinks = @"[{\"Get DowntownLA!\",\"href\":\"http://www.facebook.com/DowntownLA.com/\"}]";
dialog.attachment = [NSString stringWithFormat:
                     @"{ \"name\":\"%@\","
                     "\"href\":\"%@\","
                     "\"caption\":\"%@\",\"description\":\"%@\","
                     "\"media\":[{\"type\":\"image\","
                     "\"src\":\"%@\","
                     "\"href\":\"%@\"}],"
                     "\"properties\":{\"%@\":{\"text\":\"%@\",\"href\":\"%@\"}}}", @"name: priya",@"href nothing",@"cation nothing",@"description nothin", @"imageSource nothing ", @"imageHref nothing", @"linkTitle nothing", @"linkText nothing", @"linkHref nothing"];


[dialog show];

请告诉我哪里出错了！！！！！！

在模拟器上出现的错误是：应用程序响应错误 - 后操作链接必须是有效的 URls。您可以看到这一点，因为您是该应用的开发者之一。

我有这种方式上传图片

- (void) postOnFBWall

{

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:2];

//create a UIImage (you could use the picture album or camera too)
UIImage *picture = imgUploadPhoto.image;

//create a FbGraphFile object insance and set the picture we wish to publish on it
FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture];

//finally, set the FbGraphFileobject onto our variables dictionary....
[variables setObject:graph_file forKey:@"file"];

NSString * messageValue = [NSString stringWithFormat:@"Menu Name: %@, Restaurant: %@, Category: %@, Comment: %@",txtNameofMenu.text,txtRestaurant.text,categoryLbl.text,txtViewComment.text];

[variables setObject:[NSString stringWithFormat:@"%@",messageValue] 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 = [[FBRequestWrapper defaultManager] doGraphPost:@"me/photos" withPostVars:variables];
NSLog(@"postPictureButtonPressed:  %@", fb_graph_response.htmlResponse);

}
