iOS Facebook SDK 3.1检索返回null的朋友生日 [英] iOS Facebook SDK 3.1 Retrieve friend birthday returning null

问题描述

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:

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);
    }
}];

朋友姓名没问题，但朋友生日或不是基本朋友数据之一的所有数据都返回 null.请注意，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:

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];
     }];
 }

这里需要一些帮助，我已经尝试了所有方法.

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

推荐答案

我也有同样的问题，我是这样解决的.

I have the same problem and i solve this way.

• 首先，请确保您拥有正确的权限.

• 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: .....

那么，不要使用 requestForMyFriends.我尝试了几种方法(更改 FBRequest 和这类事情

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

检查权限并确保它是您需要的权限.

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

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

现在以这种方式生成 FBRequest.

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]);
 }}];

我终于得到了这个数据.希望对你有帮助

I finally get this data. I hope it helps you
