FBError.hFBErrorCategory enumIndicates the Facebook SDK classification for the error
typedef enum { FBErrorCategoryInvalid = 0, FBErrorCategoryRetry = 1, FBErrorCategoryAuthenticationReopenSession = 2, FBErrorCategoryPermissions = 3, FBErrorCategoryServer = 4, FBErrorCategoryThrottling = 5, FBErrorCategoryUserCancelled = 6, FBErrorCategoryFacebookOther = -1, FBErrorCategoryBadRequest = -2, } FBErrorCategory; | 常数 | 描述 |
|---|---|
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.hFBErrorCodeError codes returned by the Facebook SDK in NSError.
typedef enum FBErrorCode { FBErrorInvalid = 0, FBErrorOperationCancelled, FBErrorLoginFailedOrCancelled, FBErrorRequestConnectionApi, FBErrorProtocolMismatch, FBErrorHTTPError, FBErrorNonTextMimeTypeReturned, FBErrorDialog, FBErrorAppEvents, FBErrorSystemAPI, FBErrorPublishInstallResponse, FBErrorAppActivatedWhilePendingAppCall, FBErrorUntrustedURL, FBErrorMalformedURL, } FBErrorCode; | 常数 | 描述 |
|---|---|
FBErrorInvalid | Like nil for FBErrorCode values, represents an error code that has not been initialized yet. |
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. |
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 |
