如何使用Facebook Graph API for iPhone發佈到朋友牆

Question

我想在用戶朋友牆上張貼一些東西。

我使用它來發布到用戶牆上

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]; 

但我需要在我的朋友牆上張貼。我怎麼能這樣做

在這post他們提到了關於targetId我必須做些什麼。

Answer 1

您是否嘗試過使用，

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

UPDATE：

張貼在牆上的朋友將不再與圖形API的工作。相反，你必須使用FBDialog。

Answer 2

@mAc

您必須先向Facebook授權。然後你實現'FBRequestDelegate'方法給你的班級。然後，讓與圖形API的請求之下

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

一旦你的請求成功給出，API將調用委託方法「requestDdidLoad」，

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

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

} 

形式的結果，你會得到frieds頁ID
