See more Facebook Examples

Demonstrates how to read the contents of a single Facebook post. A post is an individual entry in a profile's feed. The profile could be a user, page, app, or group. Swift

func chilkatTest() {
    var success: Bool = false

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  This example assumes a previously obtained an access token
    let oauth2 = CkoOAuth2()!
    oauth2.accessToken = "FACEBOOK-ACCESS-TOKEN"

    let rest = CkoRest()!

    //  Connect to Facebook...
    success = rest.connect(hostname: "graph.facebook.com", port: 443, tls: true, autoReconnect: true)
    if success == false {
        print("\(rest.lastErrorText!)")
        return
    }

    //  Provide the authentication credentials (i.e. the access key)
    rest.setAuthOAuth2(authProvider: oauth2)

    //  This example assumes a post id was already retrieved.
    //  For example, it could've been retrieved by reading the user's feed:
    //  See Parsing the Facebook User Feed for code showing how to parse the JSON feed content.

    sbPath.append(value: postId)

    //  This example will select almost all the possible fields.
