如何使用Facebook Graph API for iPhone发布到朋友墙

我想在用户朋友墙上张贴一些东西。

我用它来张贴到用户墙上

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: @"Share on Facebook", @"user_message_prompt", actionLinksStr, @"action_links", attachmentStr, @"attachment",nil]; [facebook dialog:@"feed" andParams:params andDelegate:self]; 

但是我需要在我的朋友墙上张贴。 我怎样才能做到这一点

在这篇文章中，他们提到了关于targetId我必须做些什么。

Answer 1

你有没有尝试过使用，

 [facebook requestWithGraphPath:@"[friend_ID]/feed" andParams:params andHttpMethod:@"POST" andDelegate:self]; 

更新：

张贴在朋友墙上将无法使用Graph API。 相反，你必须使用FBDialog。

@苹果电脑

您必须先授权Facebook。 然后你执行“FBRequestDelegate”方法到你的class级。 然后用图API提出请求，如下所示

 [facebook requestWithGraphPath:@"/me/friends" andDelegate:self]; 

一旦你的请求成功，API将调用委托方法“requestDdidLoad”，

 -(void)request:(FBRequest *)request didLoad:(id)result { NSLog(@"Result: %@", result); } 

形成结果你会得到油炸页面的ID
