Represents a request to the Facebook Graph API.

Discussion:

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:.

setGraphErrorRecoveryDisabled:

If set, disables the automatic error recovery mechanism.

ПараметрОписание
disable

Whether to disable the automatic error recovery mechanism

- (void) setGraphErrorRecoveryDisabled:(BOOL)disable;
Discussion:

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:].
