问题描述

我正在检索Facebook朋友的生日数据，但是它返回null。
我使用这个代码：

  FBRequest * friendsRequest = [FBRequest requestForMyFriends]; 
 [friendsRequest startWithCompletionHandler：^（FBRequestConnection * connection，
 NSDictionary * result，
 NSError * error）{
 NSArray * friends = [result objectForKey：@data]; 
 NSLog（@Found：％i friends，friends.count）; 
（NSDictionary< FBGraphUser> *朋友的朋友）{
 NSLog（@我有一个名为％@  -  birthday％@的朋友，friend.name，friend.birthday）; 
} 
}];朋友的名字可以，但朋友的生日或所有不是基本的朋友数据之一的数据，是
  

<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：permission 
 allowLoginUI：YES 
 completionHandler：
 ^（FBSession * session，
 FBSessionState状态，NSError *错误）{
 [self sessionStateChanged：session state：state error：error]; 
}]; 
} 
  

在这里需要一些帮助，我已经尝试过一切。

解决方案

我有同样的问题，我解决这个问题。

• 首先，请确保您具有正确的权限。

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




• 然后，不要使用requestForMyFriends。我尝试几种方式（更改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）; 
    / pre> 




• 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名称]，[朋友生日]）; 
  }}; 
    

我终于得到这个数据，希望它能帮助你

I'm trying to retrieve birthday data of facebook friends, but it's returning null. I'm using this code:

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);
    }
}];

Friend name is ok, but friend birthday or all data that is not one of the basics friends data is returning null. Note i'm already added user_birthday and friends_birthday permissions in facebook.com app page and in openSession method (login):

- (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];
     }];
 }

Needing some help here, i've already tried everything.

解决方案

I have the same problem and i solve this way.

• First of all, be sure that you have the correct permissions.

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

• Then, DO NOT USE requestForMyFriends. I try in several ways ( changing the FBRequest and this kind of things

• Check the permissions and be sure that it was the permissions you need.

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

• Now generate the FBRequest this way.

  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]);
   }}];
  

I finally get this data. I hope it helps you
