Facebook SDK好友列表请求

Question

当我尝试加载我所有的Facebook朋友时，我收到一个时间请求超时错误。

我有FBSessionOpen状态。 我的代码：

[FBRequestConnection startForMyFriendsWithCompletionHandler:^(FBRequestConnection *connection, id data, NSError *error) {
    if(error) {
        NSLog(@"Error: %@", error);
        [self.delegate didFinishLoadingFriendsWithResult:[ErrorResponse errorResponseWithMessage:@"Failed to load user friends from Facebook"] succes:NO];
        return;
    }
    NSArray* friends = (NSArray*)[data data];
    NSLog(@"You have %d friends", [friends count]);
    NSLog(@"Friends: %@", friends);
    [self.delegate didFinishLoadingFriendsWithResult:friends succes:YES];
}];

错误信息：

    "read_friendlists"
)>}

知道我在做什么错吗？

Answer 1

看起来您只是没有从Facebook请求所需的许可。 只需使用

[FBSession openActiveSessionWithReadPermissions:[NSArray arrayWithObjects:@"read_friendlists", @"user_status", @"friends_status", nil] allowLoginUI:allowLoginUI completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {

    [self sessionStateChanged:session state:status error:error];


}];

接着

 FBRequest* friendsRequest = [FBRequest requestForMyFriends];
friendsRequest.session = FBSession.activeSession;

[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
        NSDictionary* result,
        NSError *error) {
    NSArray* friends = [result objectForKey:@"data"];
    NSLog(@"Found: %i friends", friends.count);
    NSLog(@"friends: %@", result);
    for (NSDictionary<FBGraphUser>* friend in friends) {
        NSLog(@"I have a friend named %@ with id %@", friend.name, friend.id);
    }
}];
