Question

我已经关注了图表api，但我得到了响应

context =     {
    id = dXNlcl9jb250ZAXh0OgGQ2NxhPU1adsVlI9wHXlABJbFICZC9PYfcDq57EiAdimkf6Um0P7dgco2lU1qdiM98jXp5hXpZCVkjBeN0DHCROSZAjio6JAD7gmkIZCqTxVp6dNwZD;
};
id = 1306652987;

}

我的代码是

FBSDKAccessToken *access = [FBSDKAccessToken currentAccessToken];
if (access!=nil)
{
    NSDictionary *params = @{
                             @"fields": @"context.fields(mutual_friends)",
                             };
    /* make the API call */


    FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                  initWithGraphPath:@"1306652987"
                                  parameters:params
                                  HTTPMethod:@"GET"];
    [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                          id result,
                                          NSError *error) {
        NSLog(@"result %@",result);
        // Handle the result
    }];
}
else
{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"public_profile", @"email",@"user_friends"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
 {
     if (error)
     {
         // Process error
     }
     else if (result.isCancelled)
     {
         // Handle cancellations
     }
     else
     {
         ///me/mutualfriends/[OTHER ID]/?fields=name,picture
         NSDictionary *params = @{
                                  @"fields": @"context.fields(mutual_friends)",
                                  };
         /* make the API call */

         FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                       initWithGraphPath:@"1306652987"
                                       parameters:params
                                       HTTPMethod:@"GET"];
         [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                               id result,
                                               NSError *error) {
             NSLog(@"result %@",result);
             // Handle the result
         }];
         if ([result.grantedPermissions containsObject:@"email"])
         {
             NSLog(@"result is:%@",result);
         }
     }
 }];

}

但是在图形API资源管理器中我得到了正确的输出，其中有共同的朋友姓名和身份以及共同朋友的总数，但我无法在我的代码中获得完整的答案

我遇到了同样的问题。我犯了使用id / user_id而不是上下文id的错误。

CursorLoader

所以它应该是（在Swift中）

context =     {
    id = dXNlcl9jb250ZAXh0OgGQ2NxhPU1adsVlI9wHXlABJbFICZC9PYfcDq57EiAdimkf6Um0P7dgco2lU1qdiM98jXp5hXpZCVkjBeN0DHCROSZAjio6JAD7gmkIZCqTxVp6dNwZD;
};
id = 1306652987;

也！共同的朋友必须已登录应用程序并获得“user_friends”的App权限。

所以你的登录应该是这样的：

 FBSDKGraphRequest(graphPath: "dXNlcl9jb250ZAXh0OgGQ2NxhPU1adsVlI9wHXlABJbFICZC9PYfcDq57EiAdimkf6Um0P7dgco2lU1qdiM98jXp5hXpZCVkjBeN0DHCROSZAjio6JAD7gmkIZCqTxVp6dNwZD", parameters: nil).startWithCompletionHandler({ (connection, result, error) -> Void in
        if (error == nil){
            //everything works print the user data
            print(result)
        }  else {
            print(error.description)
        }
    })

如何使用Facebooksdk列出iOS中的共同朋友？
