GRPC是一个高性能、通用的开源RPC框架，基于HTTP/2协议标准和Protobuf序列化协议开发，支持众多的开发语言。。。更多介绍
编写Proto(
asset.proto)(这里使用server写的没有自己写)
syntax = "proto3";
option java_multiple_files = true;
option java_package = "io.grpc.examples.proto.asset";
option java_outer_classname = "AssetProto";
package nameservers;
// 定义服务
service AssetService {
// 服务中的方法，以流的方式返回
rpc getAsset (User) returns (stream Asset) {
}
}
message User {
string account = 1;
}
message Asset {
string account=1;
int64 cash = 2;
int64 timestamp = 3;
}
编写
Podspec:

# Run protoc with the Objective-C and gRPC plugins to generate protocol messages and gRPC clients.
s.dependency "!ProtoCompiler-gRPCPlugin", "~> 1.0"
# Pods directory corresponding to this app's Podfile, relative to the location of this podspec.
pods_root = 'Pods'
# Path where Cocoapods downloads protoc and the gRPC plugin.

# Files generated by protoc

end
s.pod_target_xcconfig = {
# This is needed by all pods that depend on Protobuf:

# This is needed by all pods that depend on gRPC-RxLibrary:
'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES',
}
end
Podfile:
platform :ios, '8.0'
target 'GRPCDemo' do
inhibit_all_warnings! #屏蔽所有warning
pod 'gRPC'
pod 'GRPCDemo', :path => '.'
use_frameworks!
end
pod intall
引入头文件
*.pbobjc.h*.pbrpc.h
Asset demo使用:
User *user = [[User alloc] init];
user.account = @"";
// 服务中的方法，以流的方式返回
[service getAssetWithRequest:user eventHandler:^(BOOL done, Asset * _Nullable response, NSError * _Nullable error) {
if (error) {
NSLog(@"%@", error);
}
if (response) {
NSLog(@"%lld", response.cash);
}
}];
