我正在尝试使用 Facebook Feed Dialog 发布文本和图像，我可以发布到我自己的墙上，但无法标记朋友。我可以从 FBFriendPickerViewController 中选择一个朋友，但是当我点击完成但我收到返回错误 5。在 stackoverflow 问题之一（发布状态更新时 ios-Facebook SDK 3.0 错误 5）中，有几种方法可以导致此错误，我已经纠正了该问题中提到的所有可能方式。
并且提要对话框是否正确 [FBRequestConnection startWithGraphPath:@"%@/feed" 参数：params
这是我的代码，
- (IBAction)pickFriendsList:(UIButton *)sender
{
FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
friendPickerController.title = @"Pick Friends";
[friendPickerController loadData];
[friendPickerController presentModallyFromViewController:self animated:YES handler:
^(FBViewController *sender, BOOL donePressed) {
if (!donePressed) {
return;
}
NSString* fid;
NSString* fbUserName;
for (id<FBGraphUser> user in friendPickerController.selection)
{
NSLog(@"\nuser=%@\n", user);
fid = user.id;
fbUserName = user.name;
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"aaaaaa", @"message", @"http://webecoist.momtastic.com/wp-content/uploads/2009/01/nature-wonders.jpg", @"picture", @"My Susfsdfsdfs sdf sfsdfp", @"name", nil];
NSLog(@"\nparams=%@\n", params);
[FBRequestConnection startWithGraphPath:@"%@/feed" 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];
NSLog(@"%@ alertview description",alertView.message);
}
];
}
}];
}
错误 ：
