Constante | Description |
---|---|
FBErrorCategoryInvalid | Indicates that the error category is invalid and likely represents an error that is unrelated to Facebook or the Facebook SDK |
FBErrorCategoryRetry | Indicates that the error may be authentication related but the application should retry the operation. This case may involve user action that must be taken, and so the application should also test the fberrorShouldNotifyUser property and if YES display fberrorUserMessage to the user before retrying. |
FBErrorCategoryAuthenticationReopenSession | Indicates that the error is authentication related and the application should reopen the session |
FBErrorCategoryPermissions | Indicates that the error is permission related |
FBErrorCategoryServer | Indicates that the error implies that the server had an unexpected failure or may be temporarily down |
FBErrorCategoryThrottling | Indicates that the error results from the server throttling the client |
FBErrorCategoryUserCancelled | Indicates the user cancelled the operation |
FBErrorCategoryFacebookOther | Indicates that the error is Facebook-related but is uncategorizable, and likely newer than the current version of the SDK |
FBErrorCategoryBadRequest | Indicates that the error is an application error resulting in a bad or malformed request to the server. |
FBError.h
NS_ENUM (NSUInteger, FBErrorCode)
Error codes returned by the Facebook SDK in NSError.
typedef NS_ENUM(NSUInteger, FBErrorCode) { FBErrorInvalid = 0, FBErrorOperationCancelled, FBErrorLoginFailedOrCancelled, FBErrorRequestConnectionApi, FBErrorProtocolMismatch, FBErrorHTTPError, FBErrorNonTextMimeTypeReturned, FBErrorDialog, FBErrorAppEvents, FBErrorSystemAPI, FBErrorPublishInstallResponse, FBErrorAppActivatedWhilePendingAppCall, FBErrorUntrustedURL, FBErrorMalformedURL, FBErrorSessionReconnectInProgess, FBErrorOperationDisallowedForRestrictedTreament, };
Constante | Description |
---|---|
FBErrorInvalid | Like nil for FBErrorCode values, represents an error code that has not been initialized yet. |
FBErrorOperationCancelled | The operation failed because it was cancelled. |
FBErrorLoginFailedOrCancelled | A login attempt failed |
FBErrorRequestConnectionApi | The graph API returned an error for this operation. |
FBErrorProtocolMismatch | The operation failed because the server returned an unexpected response. You can get this error if you are not using the most recent SDK, or if you set your application's migration settings incorrectly for the version of the SDK you are using. If this occurs on the current SDK with proper app migration settings, you may need to try changing to one request per batch. |
FBErrorHTTPError | Non-success HTTP status code was returned from the operation. |
FBErrorNonTextMimeTypeReturned | An endpoint that returns a binary response was used with FBRequestConnection. Endpoints that return image/jpg, etc. should be accessed using NSURLRequest |
FBErrorDialog | An error occurred while trying to display a native dialog |
FBErrorAppEvents | An error occurred using the FBAppEvents class |
FBErrorSystemAPI | An error occurred related to an iOS API call |
FBErrorPublishInstallResponse | An error occurred while trying to fetch publish install response data |
FBErrorAppActivatedWhilePendingAppCall | The application had its applicationDidBecomeActive: method called while waiting on a response from the native Facebook app for a pending FBAppCall. |
FBErrorUntrustedURL | The application had its openURL: method called from a source that was not a Facebook app and with a URL that was intended for the AppBridge |
FBErrorMalformedURL | The URL passed to FBAppCall, was not able to be parsed |
FBErrorSessionReconnectInProgess | The operation failed because the session is currently busy reconnecting. |
FBErrorOperationDisallowedForRestrictedTreament | Reserved for future use. |
These are valid only in the scope of FacebookSDKDomain.

Constante | Description |
---|---|
FBAppCallErrorUnknown | A general error in processing an FBAppCall, without a known cause. Unhandled exceptions are a good example |
FBAppCallErrorUnsupported | The FBAppCall cannot be processed for some reason |
FBAppCallErrorUnknownMethod | The FBAppCall is for a method that does not exist (or is turned off) |
FBAppCallErrorServiceBusy | The FBAppCall cannot be processed at the moment, but can be retried at a later time. |
