Facebook Graph API GET request - Should contain "fields" parameter (Swift, Facebook SDK v4.5.1)

this line needs a parameters value that is NOT nil

let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)

I'll expand more, for example, and this is psuedo code of sorts:

so for ObjC it would be this, for example, so the the above would read the following:

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

In swift it would be something similar

something like this:

parameters:["fields": "email"]

This is for just two fields, and again it's psuedo code, but you need to specify the parameters


UPDATE:

Im adding this update to show folks where you find the parameters for the fields as described above, here's a quick link:

Here's the Paramters field info (this should stay roughly static with FBSDK, some of this is "core" which means it won't really change that much, but I'll update whenever I can):

use "fields" as Key and then comma separate your values

let params = ["fields": "email, friends"]

In Obj-C insert in the logInWithReadPermissions method:

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

if you leave nil in parameters you only receive id and name in the result object, although you have set for example:

NSArray *permissionsArray = @[ @"email", @"public_profile"];

It´s not very clear in the documentation, hope it can helps.


I had the same problem, but adding field options would generate a request error when fetching the user photo. I solved this problem by adding a simple parameters:@{@"fields": @""} to the code:

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:[NSString stringWithFormat:@"me/picture"]
                              parameters:@{@"fields": @""}
                              HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error) {
    if (!error) {
        // success
    } else {
        // fail
    }}
];
