// 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

// Connect to Facebook.

// Provide the authentication credentials (i.e. the access key)
[rest SetAuthOAuth2: oauth2];

// Indicate that we only want the photos the user has personally uploaded.

// We could limit the number of photos by setting a limit.
[rest AddQueryParam: @"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.
