Looks like you now need to the combination of the id of the user or page that made the post (or who’s wall it is on), an underscore, and then the post id.

For your example post, `10153513872748291`, that is made by a page `Drama-addict`, that has the id `141108613290` – so `141108613290_10153513872748291` will work.

And so does `788239567865981_10153513872748291`, because `788239567865981` is the id of the user making the post.

I&#39;m trying to mock a repository&#39;s method like that

    public async Task&lt;WhitelistItem&gt; GetByTypeValue(WhitelistType type, string value)

using Moq ReturnsAsync, like this:

    static List&lt;WhitelistItem&gt; whitelist = new List&lt;WhitelistItem&gt;();
    
    var whitelistRepositoryMock = new Mock&lt;IWhitelistRepository&gt;();
    
    whitelistRepositoryMock.Setup(w =&gt; w.GetByTypeValue(It.IsAny&lt;WhitelistType&gt;(), It.IsAny&lt;string&gt;()))
                                        .ReturnsAsync((WhitelistType type, string value) =&gt;
                                        {
                                            return (from  item in whitelist
                                                    where item.Type == type &amp;&amp; item.Value == value
                                                    select item).FirstOrDefault();
                                        });

but i&#39;m getting this error in the line &quot;... ReturnsAsync((WhitelistType type...): 

&gt; Cannot convert lambda expression to type &#39;Model.WhitelistItem&#39; because
&gt; it is not a delegate type

WhitelistType is an Enum like that:


    public enum WhitelistType
        {
            UserName,
            PostalCode
        }

I searched by hours and didn&#39;t found any answer to my problem.

Any clues?

Python pandas has a pct_change function which I use to calculate the returns for stock prices in a dataframe:

    ndf[&#39;Return&#39;]= ndf[&#39;TypicalPrice&#39;].pct_change()
I am using the following code to get logarithmic returns, but it gives the exact same values as the pct.change() function:

    ndf[&#39;retlog&#39;]=np.log(ndf[&#39;TypicalPrice&#39;].astype(&#39;float64&#39;)/ndf[&#39;TypicalPrice&#39;].astype(&#39;float64&#39;).shift(1))
    #np is for numpy

I just tried through the Graph API Explorer with this path /v2.4/10153513872748291 and I&#39;ve got this result:

    {

        &quot;code&quot;: 12
      }
    }

But https://developers.facebook.com/docs/reference/api/post/ doesn&#39;t say anything about deprecation.

I&#39;m not sure if I miss something, or there&#39;s another way to get info about an individual post.

Edit: v2.3 works, but v2.4 is the latest one.

Have you had any experience in Facebook in-app browser detection?
What&#39;s the core difference in user agent?

I don&#39;t want to know if it is a only mobile/ios/chrome. I need to know whether user agent is specific from *Facebook in-app browser*

While submitting my app to the App Store, I got this message: &quot;Your app is using the Advertising Identifier (IDFA). You must either provide details about the IDFA usage or remove it from the app and submit your binary again.&quot;

I am no longer displaying ads so I said that I was not using the IDFA when I was asked. I also tried submitting the app by saying that I was using the IDFA to display targeted ads. 

When I WAS displaying ads, I was using MoPub and Facebook Audience Network. Is there a way to see where I was using the IDFA?

My iOS app uses Facebook&#39;s Graph API Request during sign up to get user information, which worked fine prior to upgrading to Facebook&#39;s newest SDK. After upgrading, I&#39;m getting a runtime error stating: &quot;FBSDKLog: starting with Graph API v2.4, GET requests for /me should contain an explicit &quot;fields&quot; parameter&quot;.

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

I&#39;ve followed [this](https://developers.facebook.com/docs/ios/ios9) guide to update my application to use Facebook SDK 4.6 to work properly when built with the iOS 9 SDK.

When I tap the login button now, a Safari view controller gets presented (shouldn&#39;t it redirect to the Facebook app?), but after accepting permission the Safari view controller is never dismissed. It loads a new blank page and sits there doing nothing. If I tap the Done button, the returned `FBSDKLoginManagerLoginResult`&#39;s `isCancelled` is true.

Is it normal that the SDK is choosing the Safari view controller over the Facebook app? And why am I not getting callbacks after login is complete?

Facebook SDK login never calls back my application on iOS 9

When I click on login with Facebook button, it is opening safari browser and getting closed immediately. Noticed error on the console.

Any help?


facebook login issue - canOpenURL: failed for URL: &quot;fbauth2:///&quot; - error: &quot;(null)&quot;

While using the [facebook debugger](https://developers.facebook.com/tools/debug/og/object/), it complains:

&gt; Warning
fb:app_id hasn&#39;t been included in the meta tags. Specify the app ID so that stories shared to Facebook will be properly attributed to the app. Alternatively, app_id can be set in url when open the share dialog. Otherwise, the default app id( 966242223397117 ) will be assigned.

I don&#39;t understand why I have such a message, since I don&#39;t have an app_id for my website, and I shouldn&#39;t need why since I&#39;m not doing any facebook connect or using any of their plugin. 

Am I missing something, or is it simply that facebook wants to push me to create an app for my website?
