onExtensionError

Occurs when the extension runs incorrectly.

- (void)onExtensionError:(NSString * __nullable)provider
                 extension:(NSString * __nullable)extension
                     error:(int)error
                   message:(NSString * __nullable)message;

When calling enableExtensionWithVendor(YES) fails or the extension runs in error, the extension triggers this callback and reports the error code and reason.

Parameters

provider: The name of the extension provider.
extension: The name of the extension.
error: Error code. For details, see the extension documentation provided by the extension provider.
message: Reason. For details, see the extension documentation provided by the extension provider.

            key:(NSString * __nullable)key
