如何在Facebook iOS SDK 3.1中发布给朋友的墙？ [英] How to post to a friend's wall in facebook iOS SDK 3.1?

问题描述

我的SDK 3.1适用于iOS 6发布状态更新，并且拥有我想在其墙上张贴的人的脸书用户ID。我只是想让它说嗨。到一个人的墙上。
我可以使用/ [id] / feed来定位他们的Feed，但是我必须提供一个图形对象？如果我使用startForPostWithGraphPath（）。

解决方案

我想到了！

首先当然要在这里实现FBFriendPickerDelegate，除非你已经有了他们的朋友ID了。 http://developers.facebook.com/ docs / howtos / filter-devices-friend-selector-using-ios-sdk /

然后重要的部分，如何发布到朋友的墙上： / p>

   - （void）facebookViewControllerDoneWasPressed：（id）sender 
 {
 NSString * fid; 
 NSString * fbUserName; 
 
 //从选择中获取Facebook朋友的ID。刚刚获得1。 
 for（id< FBGraphUser> user在friendPickerController.selection中）
 {
 NSLog（@\\\
user =％@ \，user）; 
 fid = user.id; 
 
 fbUserName = user.name; 
} 
 
 //发帖。 
 NSMutableDictionary * params = [[NSMutableDictionary alloc] initWithObjectsAndKeys：@Join me！，@message，@http://itunes.apple.com/my-super-app，@link ，@我的超级应用，@name，nil]; 
 
 NSLog（@\\\
params =％@ \\\
，params）; 
 
 //发贴到朋友的墙上
 [FBRequestConnection startWithGraphPath：[NSString stringWithFormat：@％@ / feed，fid]参数：params HTTPMethod：@POST
 completionHandler：^（FBRequestConnection * connection，id result，NSError * error） 
 {
 //告诉用户它有效。 
 UIAlertView * alertView = [[UIAlertView alloc] initWithTitle：@Shared
 message：[NSString stringWithFormat：@Invited％@！error =％@，fbUserName，error] 
 delegate ：nil 
 cancelButtonTitle：@OK
 otherButtonTitles：nil]; 
 [alertView show]; 
} 
]; 
 
 //关闭好友选择器。 
 [self dismissModalViewControllerAnimated：YES]; 
} 
  

I have the SDK 3.1 working for iOS 6 for posting status updates and I have the facebook user id of the person who I want to post on their wall.

I just want it to say "hi." to just one person's wall. I can target their feed with "/[id]/feed" but then I have to supply a graph object? if I use startForPostWithGraphPath() anyways.

解决方案

I figured it out!

First of course implement FBFriendPickerDelegate per here, unless you already have their friend ID somehow. http://developers.facebook.com/docs/howtos/filter-devices-friend-selector-using-ios-sdk/

Then the important part, how to post to friend's wall:

- (void)facebookViewControllerDoneWasPressed:(id)sender
{
    NSString* fid;
    NSString* fbUserName;

    // get facebook friend's ID from selection. just gets 1 right now.
    for (id<FBGraphUser> user in friendPickerController.selection)
    {
        NSLog(@"\nuser=%@\n", user);
        fid = user.id;

        fbUserName = user.name;
    }

    //Make the post.
    NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Join me!", @"message", @"http://itunes.apple.com/my-super-app", @"link", @"My Super App", @"name", nil];

    NSLog(@"\nparams=%@\n", params);

    //Post to friend's wall.
    [FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"%@/feed", fid] parameters:params HTTPMethod:@"POST"
                          completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
     {
         //Tell the user that it worked.
         UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Shared"
                                                             message:[NSString stringWithFormat:@"Invited %@! error=%@", fbUserName, error]
                                                            delegate:nil
                                                   cancelButtonTitle:@"OK"
                                                   otherButtonTitles:nil];
         [alertView show];
     }
    ];

    //Close the friend picker.
    [self dismissModalViewControllerAnimated:YES];
}
