如何在ios中获取Facebook好友列表？

Question

我试图从最近两天，但没有得到任何解决方案。 请帮帮我。我想获取的Facebook好友的好友列表中，我使用此代码

loginButton.readPermissions = 
    @[@"public_profile", @"email", @"user_friends", @"read_custom_friendlists"]; 

if ([FBSDKAccessToken currentAccessToken]) { 
     [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] 
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
      if (!error) { 
       NSLog(@"fetched user:%@", result); 
      } 
     }]; 

     FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] 
           initWithGraphPath:@"/me/taggable_friends" 
           parameters:@{@"fields": @"id, name"} 
           HTTPMethod:@"GET"]; 
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, 
             id result, 
             NSError *error) { 
    NSLog(@"%@",result); 
}]; 


    } 



    but in the response i am getting :

我得到这个输出，但这不是朋友的名单，我想完整列表如何获得该列表。 我想获得所有朋友的电子邮件，姓名和ID。 我有267的朋友，但没有显示朋友的任何细节。 请帮忙。

在此先感谢

这是我的工作代码，以获取来自Facebook的朋友。希望它能帮助你。

-(void)getFacebookFriend 
{ 
    if (FBSession.activeSession.isOpen) 
    { 
      [self ListFriend]; 
    } 
    else 
    { 
     NSArray *permissions = [[NSArray alloc] initWithObjects:@"email",@"user_friends",@"public_profile", nil]; 

     [FBSession openActiveSessionWithReadPermissions:permissions 
              allowLoginUI:YES 
             completionHandler: 
     ^(FBSession *session, 
      FBSessionState state, NSError *error) { 
      if(!error) 
      { 

       [SVProgressHUD showWithStatus:PLEASE_WAIT]; 
       [self performSelector:@selector(ListFriend) withObject:nil afterDelay:0.2]; 
      } 
      else 
       [SVProgressHUD dismiss]; 
     }]; 
    } 
} 
-(void)ListFriend 
{ 

    NSMutableDictionary *params = [NSMutableDictionary new]; 
    [params setObject:@"id, first_name, last_name, middle_name, name, email, picture" forKey:@"fields"]; 
    [params setObject:[NSString stringWithFormat:@"500"] forKey:@"limit"]; 
    if(_strPageToken.length > 0) 
    { 
     [params setObject:_strPageToken forKey:@"paging_token"]; 
     [params setObject:_strUntill forKey:@"until"]; 

    } 

    [[FBRequest requestWithGraphPath:@"me/taggable_friends" parameters:params HTTPMethod:nil] startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) 
    { 
     NSArray *aryFriend = result[@"data"]; 
     [_aryContact addObjectsFromArray:aryFriend]; 
     NSLog(@"%lu",(unsigned long)aryFriend.count); 
     NSMutableDictionary *dicPaging = result[@"paging"]; 

     if(dicPaging[@"next"]) 
     { 

      _strNextURL = [NSString stringWithFormat:@"%@",dicPaging[@"next"]]; 
     } 
     else 
     { 
      NSLog(@"Final Array count: %lu",(unsigned long)_aryContact.count); 
     } 
    }]; 
} 

Answer 2

获取权限：

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

后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]); 
}}]; 

您也可以在SDK 3.0开始尝试requestForMyFriends。注：它可以提供生日信息

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