Question

代码：

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];

    [login logInWithReadPermissions: @[@"public_profile"]
     handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
         if (error) {
             NSLog(@"Process error");
         } else if (result.isCancelled) {
             NSLog(@"Cancelled");
         } else {
             NSLog(@"result:%@", result);

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


                      }
                  }];
             }
             NSLog(@"Logged in");
         }
     }];

我使用Facebook sdk4进行登录集成。它工作正常，身份验证也获得成功。如何获取名字，姓氏，个人资料网址，生日等信息.FBSDKGrpahRequest处理程序单独返回id和name.How我能得到其他细节吗？

您需要在调用要检索的特定数据时设置参数值。例如：

 parameters:@{@"fields": @"id, name"}

这也是：

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

在上面的代码中，您将参数设置为＆＃34; nil＆＃34;，因此要使代码按照您的意愿运行，请执行以下操作：

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];

[login logInWithReadPermissions: @[@"public_profile"]
 handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
     if (error) {
         NSLog(@"Process error");
     } else if (result.isCancelled) {
         NSLog(@"Cancelled");
     } else {
         NSLog(@"result:%@", result);

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


                  }
              }];
         }
         NSLog(@"Logged in");
     }
 }];

出于您的目的，您想要请求如下参数：

parameters:@{@"fields": @"id, name, first_name, last_name, birthday, picture"}
