ios - 不在 iOS 8 中从 Facebook 获取用户的电子邮件个人信息

Question

在我的应用程序中，我必须实现 facebook 登录。基于我正在做集成的 facebook 文档，但是当我获取用户信息时，电子邮件部分对我来说是空的。有人能告诉我问题出在哪里吗？我正在使用的这段代码

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    //login.loginBehavior = FBSDKLoginBehaviorBrowser;
    [login logInWithReadPermissions:@[@"public_profile",@"email",@"user_friends"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
     {
         if (error)
         {
             // Process error
         }
         else if (result.isCancelled)
         {
             // Handle cancellations
         }
         else
         {
             if ([result.grantedPermissions containsObject:@"email"])
             {
                 NSLog(@"result is:%@",result);

                 [login logOut]; // Only If you don't want to save the session for current app
             }
         }
     }];
    if ([FBSDKAccessToken currentAccessToken])
    {
        NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);



        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

             if (!error) {



                 NSLog(@"fetched user:%@  and Email : %@", result,result[@"email"]);
             }
         }];
    }

}

出去放这个

fetched user:{
    id = 970029739773026393591;
    name = "jace";
}  and Email : (null)
FBSDKLog: starting with Graph API v2.4, GET requests for /me should contain an explicit "fields" parameter

Answer 1

Facebook 权限升级了，照这样看

改变这一行

 [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]

进入

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location , friends ,hometown , friendlists"}]
