Detailed Description

An object can implement this protocol to receive responses from server from a call.

Method Documentation

didCloseWithTrailingMetadata:error:

- (void) didCloseWithTrailingMetadata: (nullable NSDictionary *)  trailingMetadata error: (nullable NSError *)  error

optional

Issued when a call finished.

If the call finished successfully, error is nil and trailingMetadata consists any trailing metadata received from the server. Otherwise, error is non-nil and contains the corresponding error information, including gRPC error codes and error descriptions.

didReceiveInitialMetadata:

- (void) didReceiveInitialMetadata: (nullable NSDictionary *)  initialMetadata

optional

Issued when initial metadata is received from the server.

didReceiveProtoMessage:

- (void) didReceiveProtoMessage: (nullable GPBMessage *)  message

optional

Issued when a message is received from the server.

The message is the deserialized proto object.

didWriteMessage

- (void) didWriteMessage

optional

Issued when flow control is enabled for the call and a message (written with writeMessage: method of GRPCStreamingProtoCall or the initializer of GRPCUnaryProtoCall) is passed to gRPC core with SEND_MESSAGE operation.

Property Documentation
