In general, in response to an error connecting to Facebook, an application should, retry the operation, request permissions, reconnect the application, or prompt the user to take an action. The error category can be used to understand the class of error received from Facebook. For more infomation on this see https://developers.facebook.com/docs/reference/api/errors/

shouldNotifyUserForError:

If YES indicates that a user action is required in order to successfully continue with the facebook operation

參數說明
error

The error to inspect.

+ (BOOL) shouldNotifyUserForError:(NSError *)error;
Discussion:

In general if this returns NO, then the application has a straightforward mitigation, such as retry the operation or request permissions from the user, etc. In some cases it is necessary for the user to take an action before the application continues to attempt a Facebook connection.
