iOS Facebook SDK 3.1检索返回null的朋友生日

Question

我正在尝试检索facebook朋友的生日数据,但它返回null.我正在使用此代码:

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

朋友的名字还可以,但朋友生日或所有不是基本朋友数据的数据都返回null.注意我已经在facebook.com应用页面和openSession方法(登录)中添加了user_birthday和friends_birthday权限:

- (void)openSession
{

    NSArray *permissions = [[NSArray alloc] initWithObjects:
                            @"user_birthday",
                            @"friends_birthday",
                            nil];


    [FBSession openActiveSessionWithReadPermissions:permissions
                                       allowLoginUI:YES
                                  completionHandler:
     ^(FBSession *session,
       FBSessionState state, NSError *error) {
         [self sessionStateChanged:session state:state error:error];
     }];
 }

需要一些帮助,我已经尝试了一切.

我有同样的问题,我解决这个问题.

• 首先,请确保您拥有正确的权限.

   NSArray *permissions = @[@"user_birthday", @"friends_hometown",
                          @"friends_birthday", @"friends_location"];
  [FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:YES completionHandler: .....
  

• 然后,不要使用requestForMyFriends.我尝试了几种方式(改变FBRequest和这种事情

• 检查权限并确保它是您需要的权限.

  NSLog(@"permissions::%@",FBSession.activeSession.permissions);
  

• 现在以这种方式生成FBRequest.

  FBRequest *friendRequest = [FBRequest requestForGraphPath:@"me/friends?fields=name,picture,birthday,location"];
   [ friendRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
      NSArray *data = [result objectForKey:@"data"];
      for (FBGraphObject<FBGraphUser> *friend in data) {
          NSLog(@"%@:%@", [friend name],[friend birthday]);
   }}];
  

我终于得到了这些数据.我希望它对你有所帮助
