/**
|
Represents a request to the Facebook Graph API.
|
|
|
`FBSDKGraphRequest` encapsulates the components of a request (the
|
Graph API path, the parameters, error recovery behavior) and should be
|
used in conjunction with `FBSDKGraphRequestConnection` to issue the request.
|
|
Nearly all Graph APIs require an access token. Unless specified, the
|
`[FBSDKAccessToken currentAccessToken]` is used. Therefore, most requests
|
will require login first (see `FBSDKLoginManager` in FBSDKLoginKit.framework).
|
|
A `- start` method is provided for convenience for single requests.
|
|
By default, FBSDKGraphRequest will attempt to recover any errors returned from
|
Facebook. You can disable this via `disableErrorRecovery:`.

|
