單純的抄襲復制~~~~~~~~~~

一 grpc 的簡介（可參考谷歌http://www.grpc.io/）

1.配置可參考http://www.grpc.io/docs/quickstart/objective-c.html

配置要求：

cocoaPods: Version 1.0 or Higher ? 查看版本 pod --Version

Xcode: version 7.2 or higher ? ?：installed:sh [sudo] xcode-select --instal

Install with Homebrewsh brew install autoconf automake libtool pkg-config

2.配置好這些內(nèi)容就去下載官網(wǎng)demo

下載：

?$git clone https://github.com/grpc/grpc.git

Install gRPC plugins and libraries：

$cd grpc

$git submodule update--init

$make

$[sudo]make install

Install protoc compiler：

$brew tap grpc/grpc

$brew install google-protobuf

Run the server：

$cd examples/cpp/helloworld

$make

$./greeter_server&

Run the client：

$cd../../objective-c/helloworld

$pod install

Run the client app：

$ openHelloWorld.xcworkspace

3.以上是官網(wǎng)的demo,以下是自己的操作

（1）創(chuàng)建Xcode你的工程。創(chuàng)建.podspec 和Podfile

? ? $ pod spec create iOS_Demo?

這樣創(chuàng)建ProtoTest.podspec文件 然后編輯此文件可參考（http://guides.cocoapods.org/syntax/podspec.html）

我的.podspec文件如下：

Pod::Spec.new do |s|

? s.name ? ? ? ? = "ProtoTest"

? s.version? ? ? = "0.0.1"

?s.license? = "New BSD"

?s.homepage = "http://www.grpc.io/"

? s.summary = "HelloWorld example!!!"

? s.source = { :git => 'https://github.com/grpc/grpc.git' }

? s.author ? ? ? ? ? ? = { "" => "1602333924@qq.com" }

? s.source_files? = "Classes", "Classes/**/*.{h,m}"

? s.exclude_files = "Classes/Exclude"

? s.ios.deployment_target = "7.1"

? s.osx.deployment_target = "10.9"

? # Base directory where the .proto files are.

? src = "../../protos"

? # 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.

? protoc_dir = "#{pods_root}/!ProtoCompiler"

? protoc = "#{protoc_dir}/protoc"

? plugin = "#{pods_root}/!ProtoCompiler-gRPCPlugin/grpc_objective_c_plugin"

? # Directory where the generated files will be placed.

? dir = "#{pods_root}/#{s.name}"

? s.prepare_command = <<-CMD

? ? mkdir -p #{dir}

? ? #{protoc} \

? ? ? ? --plugin=protoc-gen-grpc=#{plugin} \

? ? ? ? --objc_out=#{dir} \

? ? ? ? --grpc_out=#{dir} \

? ? ? ? -I #{src} \

? ? ? ? -I #{protoc_dir} \

? ? ? ? #{src}/*.proto

? CMD

? # Files generated by protoc

? s.subspec "Messages" do |ms|

? ? ms.source_files = "#{dir}/*.pbobjc.{h,m}", "#{dir}/**/*.pbobjc.{h,m}"

? ? ms.header_mappings_dir = dir

? ? ms.requires_arc = false

? ? # The generated files depend on the protobuf runtime.

? ? ms.dependency "Protobuf"

? end

? # Files generated by the gRPC plugin

? s.subspec "Services" do |ss|

? ? ss.source_files = "#{dir}/*.pbrpc.{h,m}", "#{dir}/**/*.pbrpc.{h,m}"

? ? ss.header_mappings_dir = dir

? ? ss.requires_arc = true

? ? # The generated files depend on the gRPC runtime, and on the files generated by protoc.

? ? ss.dependency "gRPC-ProtoRPC"

? ? ss.dependency "#{s.name}/Messages"

? end

? s.pod_target_xcconfig = {

? ? # This is needed by all pods that depend on Protobuf:

? ? 'GCC_PREPROCESSOR_DEFINITIONS' => '$(inherited) GPB_USE_PROTOBUF_FRAMEWORK_IMPORTS=1',

? ? # This is needed by all pods that depend on gRPC-RxLibrary:

? ? 'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES',

? }

end

以上.podspec內(nèi)容：有幾個重點

# Base directory where the .proto files are.

? src = "../../protos" ? ?#指的就是在你的xcode工程內(nèi)*.xcodeproj當前目錄 上級目錄的上級開始protos文件绊序。

? ?#{src}/*.proto ?指的的protos文件內(nèi)的.proto的內(nèi)容豪嗽。通過終端命令查找編譯。

（2）然后編譯你的podfile（$pod init ?#創(chuàng)建podfile ）,編譯podfile如下：

# Uncomment this line to define a global platform for your project

# platform :ios, '9.0'

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '8.0'

install! 'cocoapods', :deterministic_uuids => false

target 'ProtoTest' do

pod 'ProtoTest', :path => '.'

end

注意：?pod 'ProtoTest', :path => '.'?是指當前目錄下查詢散劫，ProtoTest.podspec的文件。

然后通過$pod install 進行編譯grpc的庫和內(nèi)容

編譯的庫：

Downloading dependencies

Using !ProtoCompiler (3.0.0)

Using !ProtoCompiler-gRPCPlugin (1.0.0)

Using BoringSSL (6.0)

Using Protobuf (3.1.0)

Using gRPC (1.0.0)

Using gRPC-Core (1.0.0)

Using gRPC-ProtoRPC (1.0.0)

Using gRPC-RxLibrary (1.0.0)

這樣庫的就編譯好了。并且在你工程中的pod內(nèi)也就有對應的*.proto ? 對應編譯出來的*.pbobjc.h/*.pbobjc.m/*.pbrpc.h/*.pbrpc.m ?

4.下面就說說如何去利用

類中導入*.pbobjc.h/?*.pbobjc.m? /*.pbrpc.h/*.pbrpc.m ?估蹄，進行利用

比如我發(fā)起的網(wǎng)絡(luò)請求：

? ??NSURL?*url = [NSURL?URLWithString:@"http://115.239.231.164:8080//tv-http/user/verifyPhone"];

?NSMutableURLRequest?*request = [NSMutableURLRequest?requestWithURL:url];

?//? ? request.timeoutInterval = 0.5;

? ? request.HTTPMethod?=?@"POST";

[request?addValue:@"application/x-protobuf"?forHTTPHeaderField:@"Content-Type"];

? ??BaseRequest?*testBaseRequest = [[BaseRequest?alloc]?init]; ? ?//?ProtocBaseRequest.pbobjc.h ?中BaseRequest的類颂碧，中闡述如

? ?/**********?ProtocBaseRequest.proto如下：**************/

? ? ? ? ? ? syntax = "proto3";

? ? ? ? ? ? ?message BaseRequest{

? ? ? ? ? ? string token=1;//用戶標識?zyy

? ? ? ? ? ? string p=2;//加密P zyy

? ? ? ? ? ? string sign=3;//簽名參數(shù)?zyy

? ? ? ? ? ? map SpareParameter= 4;//備用參數(shù)map zyy

? ? ? ? ? ?}

? ?/************************/

[testBaseRequest?setP:@"p->Hello"];

[testBaseRequest?setToken:@"token->hello"];

[testBaseRequest?setSign:@"sign->hello"];

? ? request.HTTPBody?= [testBaseRequest?data]; ?//testBaseRequest轉(zhuǎn)化為data請求數(shù)據(jù)

?NSURLSession?*session = [NSURLSession?sessionWithConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]];

?NSURLSessionDataTask?*task = [session?dataTaskWithRequest:request?completionHandler:^(NSData?*?_Nullable?data,?NSURLResponse?*?_Nullable?response,?NSError?*?_Nullable?error) {

?if?(error)

? ? ? ? {

?NSLog(@"error = %@",error);

? ? ? ? }

?else

? ? ? ? {?? ? ? ? ? ??

?BaseReply?*reply = [[BaseReply?alloc?]?initWithData:data?error:nil];

?BaseReply? *replyOne = [GPBMessage?parseFromData:data?error:&error];?

//ProtocBaseReply.proto ?生成的就是BaseReply

?NSLog(@"%@",result);?

? ? ? ?}

? ? }];

[task?resume];

以上的利用就是對*.pbobjc.h荠列。

對 *.pbrpc.h的利用請參考谷歌官網(wǎng)demo,
