Ios 如何使用适用于iPhone的Facebook Graph API发布到好友墙

我想在用户朋友的墙上贴些东西

我用它发布到用户墙中

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];

但是我需要在我朋友的墙上贴。我该怎么做

---

在这篇文章中，他们提到了targetId，我是否需要对此做些什么。

您是否尝试过使用

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

更新：

朋友墙上的帖子将不再适用于Graph API。相反，您必须使用FBDialog。

@mAc

你必须先授权facebook。然后对类实现“FBRequestDelegate”方法。然后使用graph API发出请求，如下所示

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

请求成功后，api将调用委托方法“RequestDddLoad”

-(void)request:(FBRequest *)request didLoad:(id)result {

    NSLog(@"Result: %@", result);

}

从结果中，您将获得frieds页面ID

-（iAction）InviteAction:（ID）sender//按钮操作
- (IBAction)InviteAction:(id)sender  // Button action 
{
    if (!FBSession.activeSession.isOpen) {
        // if the session is closed, then we open it here, and establish a handler for state changes
        [FBSession openActiveSessionWithReadPermissions:nil
