Demonstrates how to get the photos that the user has uploaded. 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)

    // Indicate that we only want the photos the user has personally uploaded.
    rest.addQueryParam(name: "type", value: "uploaded")

    // We could limit the number of photos by setting a limit.
    rest.addQueryParam(name: "limit", value: "5")

    // Gets the 1st page of photos. (Not the actual image data, but the information about each photo.)
    // See https://developers.facebook.com/docs/graph-api/reference/user/photos/ for more information.
