A formal protocol very similar to the informal protocol NSErrorRecoveryAttempting

Extends Protocol:	`NSObject`
Declared in:	`FBSDKErrorRecoveryAttempting.h`

Metodi di istanza

attemptRecoveryFromError:optionIndex:delegate:didRecoverSelector:contextInfo:

Attempt the recovery

Parametro	Descrizione
`error`	The error
`recoveryOptionIndex`	The selected option index
`delegate`	The delegate
`didRecoverSelector`	The callback selector, see discussion.
`contextInfo`	Context info to pass back to callback selector, see discussion.

- (void)

`attemptRecoveryFromError:`	`(NSError *)error`
`optionIndex:`	`(NSUInteger)recoveryOptionIndex`
`delegate:`	`(id)delegate`
`didRecoverSelector:`	`(SEL)didRecoverSelector`
`contextInfo:`	`(void*)contextInfo;`

Discussion:

Given that an error alert has been presented document-modally to the user, and the user has chosen one of the error's recovery options, attempt recovery from the error, and send the selected message to the specified delegate. The option index is an index into the error's array of localized recovery options. The method selected by didRecoverSelector must have the same signature as: - (void)didPresentErrorWithRecovery:(BOOL)didRecover contextInfo:(void *)contextInfo; The value passed for didRecover must be YES if error recovery was completely successful, NO otherwise.

FBSDKErrorArgumentCollectionKey

FBSDK_EXTER N NSString *const FBSDKErrorArgumentCollectionKey;

Discussion:

If the invalid argument is a collection, the collection can be found with this key and the individual invalid item can be found with FBSDKErrorArgumentValueKey.

Typedef

NS_ENUM

Indicates an app switch to the browser (typically for a dialog) failed.

typedef NS_ENUM(NSInteger, FBSDKErrorCode) { 
    /*!
        */
    FBSDKReservedErrorCode = 0,  /*!
        */

        */
    FBSDKBrowswerUnavailableErrorCode __attribute__ ((deprecated("use FBSDKBrowserUnavailableErrorCode instead"))) = 
    FBSDKBrowserUnavailableErrorCode, 
};

Discussion:

This error may signify that the configuration for the dialogs has not yet been downloaded from the server or that the dialog is unavailable. Subsequent attempts to use the dialog may succeed as the configuration is loaded.
