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:.

FBSDKGraphRequest.hsetGraphErrorRecoveryDisabled:If set, disables the automatic error recovery mechanism.
| Параметр | Описание |
|---|---|
disable | Whether to disable the automatic error recovery mechanism |
- (void) setGraphErrorRecoveryDisabled:(BOOL)disable;By default, non-batched FBSDKGraphRequest instances will automatically try to recover
from errors by constructing a FBSDKGraphErrorRecoveryProcessor instance that
re-issues the request on successful recoveries. The re-issued request will call the same
handler as the receiver but may occur with a different FBSDKGraphRequestConnection instance.
This will override [FBSDKSettings setGraphErrorRecoveryDisabled:].
FBSDKGraphRequest.hstartWithCompletionHandler:Starts a connection to the Graph API.
| Параметр | Описание |
