Class Methods
errorCategoryForError:

Categorizes the error, if it is Facebook related, to simplify application mitigation behavior

ParameterDescription
error

The error to be categorized.

+ (FBErrorCategory) errorCategoryForError:(NSError *)error;
Discussion:

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/

Declared In: FBErrorUtility.h
shouldNotifyUserForError:

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

ParameterDescription
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. For more infomation on this see https://developers.facebook.com/docs/reference/api/errors/

Declared In: FBErrorUtility.h
userMessageForError:

Not all Facebook errors yield a message suitable for user display; however in all cases where fberrorShouldNotifyUser is YES, this property returns a localizable message suitable for display.

ParameterDescription
error

The error to inspect.
