使用IOS SDK 3.0发布到好友墙

我可以通过以下方式在用户墙上发布图像：-

if (appDelegate.session.isOpen)
    {
        FBSession.activeSession  = appDelegate.session;            
        [FBRequestConnection startForUploadPhoto:img 
                               completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                   [self showAlert:@"eCard Posted" result:result error:error];
                               }];

    }

现在的要求是从friend picker类中挑选朋友，并将图像张贴在选定的朋友墙上/时间线上

我集成了Friends picker类，如下所示：-

if (appDelegate.session.isOpen)
    {
         FBSession.activeSession  = appDelegate.session; 
        if (self.friendPickerController == nil) {
            // Create friend picker, and get data loaded into it.
            self.friendPickerController = [[FBFriendPickerViewController alloc] init];
            self.friendPickerController.title = @"Pick Friends";
            self.friendPickerController.delegate = self;
        }

        [self.friendPickerController loadData];
        [self.friendPickerController clearSelection];            
        [self presentModalViewController:self.friendPickerController animated:YES];


   }   

现在在委托方法中：-

- (void)facebookViewControllerDoneWasPressed:(id)sender {

// we pick up the users from the selection, and create a string that we use to update the text view
// at the bottom of the display; note that self.selection is a property inherited from our base class
//UIImage *img = self.image;
    FBSession.activeSession = appDelegate.session;

for (id<FBGraphUser> user in self.friendPickerController.selection) {   

    FBSession.activeSession  = appDelegate.session; 
    if (appDelegate.session.isOpen)
    {            
        NSMutableDictionary  *postVariablesDictionary = [[NSMutableDictionary alloc] init];
       // [postVariablesDictionary setObject:@"me" forKey:@"name"]; 
       // [postVariablesDictionary setObject:self.image forKey:@"picture"];
        [postVariablesDictionary setObject:@"Sample Text" forKey:@"message"];
         NSLog(@"%@",user.id);
        [FBRequestConnection startForPostWithGraphPath:[NSString stringWithFormat:@"%@/feed",user.id] graphObject:[NSDictionary dictionaryWithDictionary:postVariablesDictionary] completionHandler:nil];


     }    
    else 
    {
        if (appDelegate.session.state != FBSessionStateCreated) {
            // Create a new, logged out session.
            appDelegate.session = [[FBSession alloc] init];
        }            
        // if the session isn't open, let's open it now and present the login UX to the user
        [appDelegate.session openWithCompletionHandler:^(FBSession *session, 
                                                         FBSessionState status, 
                                                         NSError *error) {
        }];
    } 

}

[self dismissModalViewControllerAnimated:YES];

-（void）按下FaceBookViewControllerDone:（id）发件人{
//我们从选择中选择用户，并创建一个字符串，用于更新文本视图
//请注意self.selection是从基类继承的属性
//UIImage*img=self.image；
FBSession.activeSession=appDelegate.session；
对于（self.friendPickerController.selection中的id用户）{
FBSession.activeSession=appDelegate.session；
if（appDelegate.session.isOpen）
{            
NSMutableDictionary*postVariablesDictionary=[[NSMutableDictionary alloc]init]；
//[postVariablesDictionary setObject:@“me”forKey:@“name”]；
//[postVariablesDictionary setObject:self.image-forKey:@“picture”]；
[postVariablesDictionary setObject:@“示例文本”forKey:@“消息”]；
NSLog（@“%@”，user.id）；
[FBRequestConnection startForPostWithGraphPath:[NSString stringWithFormat:@“%@/feed”，user.id]graphObject:[NSDictionary Dictionary Dictionary WithDictionary:postVariablesDictionary]completionHandler:nil]；
}    
其他的
{
if（appDelegate.session.state！=FBSessionStateCreated）{
//创建一个新的注销会话。
appDelegate.session=[[FBSession alloc]init]；
}            
//如果会话未打开，让我们现在打开它并向用户展示登录UX
[appDelegate.session openWithCompletionHandler:^（FBSession*会话，
FBSessionState状态，
N错误*错误）{
}];
} 
}
[自我解散Modalviewcontrolleranimated:是]；

}

上述委托方法始终导致错误代码=5错误。应该调用什么API才能将上述图像发布到选定的好友墙中

---

请帮助我……

最后，我可以在朋友的墙上张贴图片了

委托方法修改如下：---

- (void)facebookViewControllerDoneWasPressed:(id)sender {

// we pick up the users from the selection, and create a string that we use to update the text view
// at the bottom of the display; note that self.selection is a property inherited from our base class

FBSession.activeSession = appDelegate.session;
if (appDelegate.session.isOpen)
{            
    [FBSession openActiveSessionWithPermissions:[NSArray arrayWithObjects:@"publish_stream",@"user_photos",@"", nil]
                                   allowLoginUI:NO
                              completionHandler:^(FBSession *session,
                                                  FBSessionState status,
                                                  NSError *error) {

                                  if (error) {
                                      NSLog(@"error");
                                  } else {
                                      [FBSession setActiveSession:appDelegate.session];

                              }];

是的，在Facebook IOS SDK 3.0中。
