Facebook SDK好友列表請求

Question

當我嘗試加載我所有的Facebook好友時，我收到了一個時間請求超時錯誤。

我有FBSessionOpen狀態。 我的代碼：

[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]; 
}]; 

錯誤消息：

    "read_friendlists" 
)>} 

任何想法，我做錯了什麼？

Answer 2

看起來你只是沒有要求從Facebook所需要的權限。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]; 


}]; 

然後

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); 
    } 
}];
