Es ist eine neuere Version dieser Klasse verfügbar. Sieh sie dir an mit der aktuellsten Version.

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:.

parameters

The optional parameters dictionary.

HTTPMethod

The optional HTTP method. nil defaults to @"GET".

- (instancetype)
initWithGraphPath: (NSString *)graphPath
parameters: (NSDictionary *)parameters
HTTPMethod: (NSString *)HTTPMethod;

initWithGraphPath:parameters:tokenString:version:HTTPMethod:

Initializes a new instance.

ParameterBeschreibung
graphPath

The graph path (e.g., @"me").

parameters

The optional parameters dictionary.

tokenString

The token string to use. Specifying nil will cause no token to be used.

setGraphErrorRecoveryDisabled:

If set, disables the automatic error recovery mechanism.

ParameterBeschreibung
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:].

startWithCompletionHandler:

Starts a connection to the Graph API.

ParameterBeschreibung
handler

The handler block to call when the request completes.

- (FBSDKGraphRequestConnection *) startWithCompletionHandler:(FBSDKGraphRequestHandler)handler;
