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.
