By +walking through this example you'll learn how to: + +- Define a service in a .proto file. +- Generate client code using the protocol buffer compiler. +- Use the Objective-C gRPC API to write a simple client for your service. + +It assumes a passing familiarity with [protocol buffers](https://developers.google.com/protocol-buffers/docs/overview). +Note that the example in this tutorial uses the proto3 version of the protocol buffers language, +which is currently in alpha release: you can find out more in the [proto3 language guide](https://developers.google.com/protocol-buffers/docs/proto3) +and see the [release notes](https://github.com/google/protobuf/releases) for the new version in the +protocol buffers Github repository. + +This isn't a comprehensive guide to using gRPC in Objective-C: more reference documentation is +coming soon. + +- [Why use gRPC?](#why-grpc) +- [Example code and setup](#setup) +- [Try it out!](#try) +- [Defining the service](#proto) +- [Generating client code](#protoc) +- [Creating the client](#client) + +<a name="why-grpc"></a> +## Why use gRPC? + +With gRPC you can define your service once in a .proto file and implement clients and servers in any +of gRPC's supported languages, which in turn can be run in environments ranging from servers inside +Google to your own tablet - all the complexity of communication between different languages and +environments is handled for you by gRPC. You also get all the advantages of working with protocol +buffers, including efficient serialization, a simple IDL, and easy interface updating. + +gRPC and proto3 are specially suited for mobile clients: gRPC is implemented on top of HTTP/2, which +results in network bandwidth savings over using HTTP/1.1. Serialization and parsing of the proto +binary format is more efficient than the equivalent JSON, resulting in CPU and battery savings. And +proto3 uses a runtime that has been optimized over the years at Google to keep code size to a +minimum. The latter is important in Objective-C, because the ability of the compiler to strip unused +code is limited by the dynamic nature of the language. + + +<a name="setup"></a> +## Example code and setup + +The example code for our tutorial is in [grpc/grpc-common/objective-c/route_guide](https://github.com/grpc/grpc-common/tree/master/objective-c/route_guide). +To download the example, clone the `grpc-common` repository by running the following command: +```shell +$ git clone https://github.com/grpc/grpc-common.git +``` + +Then change your current directory to `grpc-common/objective-c/route_guide`: +```shell +$ cd grpc-common/objective-c/route_guide +``` + +Our example is a simple route mapping application that lets clients get information about features +on their route, create a summary of their route, and exchange route information such as traffic +updates with the server and other clients. + +You also should have [Cocoapods](https://cocoapods.org/#install) installed, as well as the relevant +tools to generate the client library code (and a server in another language, for testing). You can +obtain the latter by following [these setup instructions](https://github.com/grpc/homebrew-grpc). + + +<a name="try"></a> +## Try it out! + +To try the sample app, we need a gRPC server running locally. Let's compile and run, for example, +the C++ server in this repository: + +```shell +$ pushd ../../cpp/route_guide +$ make +$ ./route_guide_server & +$ popd +``` + +Now have Cocoapods generate and install the client library for our .proto files: + +```shell +$ pod install +``` + +(This might have to compile OpenSSL, which takes around 15 minutes if Cocoapods doesn't have it yet +on your computer's cache). + +Finally, open the XCode workspace created by Cocoapods, and run the app. You can check the calling +code in `ViewControllers.m` and see the results in XCode's log console. + +The next sections guide you step-by-step through how this proto service is defined, how to generate +a client library from it, and how to create an app that uses that library. + + +<a name="proto"></a> +## Defining the service + +First let's look at how the service we're using is defined. A gRPC *service* and its method +*request* and *response* types using [protocol buffers](https://developers.google.com/protocol-buffers/docs/overview). +You can see the complete .proto file for our example in [`grpc-common/protos/route_guide.proto`](https://github.com/grpc/grpc-common/blob/master/protos/route_guide.proto). + +To define a service, you specify a named `service` in your .proto file: + +```protobuf +service RouteGuide { + ... +} +``` + +Then you define `rpc` methods inside your service definition, specifying their request and response +types. Protocol buffers let you define four kinds of service method, all of which are used in the +`RouteGuide` service: + +- A *simple RPC* where the client sends a request to the server and receives a response later, just +like a normal remote procedure call. +```protobuf + // Obtains the feature at a given position. + rpc GetFeature(Point) returns (Feature) {} +``` + +- A *response-streaming RPC* where the client sends a request to the server and gets back a stream +of response messages. You specify a response-streaming method by placing the `stream` keyword before +the *response* type. +```protobuf + // Obtains the Features available within the given Rectangle. Results are + // streamed rather than returned at once (e.g. in a response message with a + // repeated field), as the rectangle may cover a large area and contain a + // huge number of features. + rpc ListFeatures(Rectangle) returns (stream Feature) {} +``` + +- A *request-streaming RPC* where the client sends a sequence of messages to the server. Once the +client has finished writing the messages, it waits for the server to read them all and return its +response. You specify a request-streaming method by placing the `stream` keyword before the +*request* type. +```protobuf + // Accepts a stream of Points on a route being traversed, returning a + // RouteSummary when traversal is completed. + rpc RecordRoute(stream Point) returns (RouteSummary) {} +``` + +- A *bidirectional streaming RPC* where both sides send a sequence of messages to the other. The two +streams operate independently, so clients and servers can read and write in whatever order they +like: for example, the server could wait to receive all the client messages before writing its +responses, or it could alternately read a message then write a message, or some other combination of +reads and writes. The order of messages in each stream is preserved. You specify this type of method +by placing the `stream` keyword before both the request and the response. +```protobuf + // Accepts a stream of RouteNotes sent while a route is being traversed, + // while receiving other RouteNotes (e.g. from other users). + rpc RouteChat(stream RouteNote) returns (stream RouteNote) {} +``` + +Our .proto file also contains protocol buffer message type definitions for all the request and +response types used in our service methods - for example, here's the `Point` message type: +```protobuf +// Points are represented as latitude-longitude pairs in the E7 representation +// (degrees multiplied by 10**7 and rounded to the nearest integer). +// Latitudes should be in the range +/- 90 degrees and longitude should be in +// the range +/- 180 degrees (inclusive). +message Point { + int32 latitude = 1; + int32 longitude = 2; +} +``` + +You can specify a prefix to be used for your generated classes by adding the `objc_class_prefix` +option at the top of the file. For example: +```protobuf +option objc_class_prefix = "RTG"; +``` + + +<a name="protoc"></a> +## Generating client code + +Next we need to generate the gRPC client interfaces from our .proto service definition. We do this +using the protocol buffer compiler (`protoc`) with a special gRPC Objective-C plugin. + +For simplicity, we've provided a [Podspec file](https://github.com/grpc/grpc-common/blob/master/objective-c/route_guide/RouteGuide.podspec) +that runs `protoc` for you with the appropriate plugin, input, and output, and describes how to +compile the generated files. You just need to run in this directory (`grpc-common/objective-c/route_guide`): + +```shell +$ pod install +``` + +which, before installing the generated library in the XCode project of this sample, runs: + +```shell +$ protoc -I ../../protos --objc_out=Pods/RouteGuide --objcgrpc_out=Pods/RouteGuide ../../protos/route_guide.proto +``` + +Running this command generates the following files under `Pods/RouteGuide/`: +- `RouteGuide.pbobjc.h`, the header which declares your generated message classes. +- `RouteGuide.pbobjc.m`, which contains the implementation of your message classes. +- `RouteGuide.pbrpc.h`, the header which declares your generated service classes. +- `RouteGuide.pbrpc.m`, which contains the implementation of your service classes. + +These contain: +- All the protocol buffer code to populate, serialize, and retrieve our request and response message +types. +- A class called `RTGRouteGuide` that lets clients call the methods defined in the `RouteGuide` +service. + +You can also use the provided Podspec file to generate client code from any other proto service +definition; just replace the name (matching the file name), version, and other metadata. + + +<a name="client"></a> +## Creating the client + +In this section, we'll look at creating an Objective-C client for our `RouteGuide` service. You can +see our complete example client code in [grpc-common/objective-c/route_guide/ViewControllers.m](https://github.com/grpc/grpc-common/blob/master/objective-c/route_guide/ViewControllers.m). +(Note: In your apps, for maintainability and readability reasons, you shouldn't put all of your view +controllers in a single file; it's done here only to simplify the learning process). + +### Constructing a client object + +To call service methods, we first need to create a client object, an instance of the generated +`RTGRouteGuide` class. The designated initializer of the class expects a `NSString *` with the +server address and port we want to connect to: + +```objective-c +#import <RouteGuide/RouteGuide.pbrpc.h> + +static NSString * const kHostAddress = @"http://localhost:50051"; + +... + +RTGRouteGuide *client = [[RTGRouteGuide alloc] initWithHost:kHostAddress]; +``` + +Notice that we've specified the HTTP scheme in the host address. This is because the server we will +be using to test our client doesn't use [TLS](http://en.wikipedia.org/wiki/Transport_Layer_Security). +This is fine because it will be running locally on our development machine. The most common case, +though, is connecting with a gRPC server on the internet, running gRPC over TLS. For that case, the +HTTPS scheme can be specified (or no scheme at all, as HTTPS is the default value). The default +value of the port is that of the scheme selected: 443 for HTTPS and 80 for HTTP. + + +### Calling service methods + +Now let's look at how we call our service methods. As you will see, all these methods are +asynchronous, so you can call them from the main thread of your app without worrying about freezing +your UI or the OS killing your app. + +#### Simple RPC + +Calling the simple RPC `GetFeature` is nearly as straightforward as calling any other asynchronous +method on Cocoa. + +```objective-c +RTGPoint *point = [RTGPoint message]; +point.latitude = 40E7; +point.longitude = -74E7; + +[client getFeatureWithRequest:point handler:^(RTGFeature *response, NSError *error) { + if (response) { + // Successful response received + } else { + // RPC error + } +}]; +``` + +As you can see, we create and populate a request protocol buffer object (in our case `RTGPoint`). +Then, we call the method on the client object, passing it the request, and a block to handle the +response (or any RPC error). If the RPC finishes successfully, the handler block is called with a +`nil` error argument, and we can read the response information from the server from the response +argument. If, instead, some RPC error happens, the handler block is called with a `nil` response +argument, and we can read the details of the problem from the error argument. + +```objective-c +NSLog(@"Found feature called %@ at %@.", response.name, response.location); +``` + +#### Streaming RPCs + +Now let's look at our streaming methods. Here's where we call the response-streaming method +`ListFeatures`, which results in our client receiving a stream of geographical `RTGFeature`s: + +```objective-c +[client listFeaturesWithRequest:rectangle + eventHandler:^(BOOL done, RTGFeature *response, NSError *error) { + if (response) { + // Element of the stream of responses received + } else if (error) { + // RPC error; the stream is over. + } + if (done) { + // The stream is over (all the responses were received, or an error occured). Do any cleanup. + } +}]; +``` + +Notice how the signature of the `eventHandler` block now includes a `BOOL done` parameter. The +`eventHandler` block can be called any number of times; only on the last call is the `done` argument +value set to `YES`. If an error occurs, the RPC finishes and the block is called with the arguments +`(YES, nil, error)`. + +The request-streaming method `RecordRoute` expects a stream of `RTGPoint`s from the cient. This +stream is passed to the method as an object of class `GRXWriter`. The simplest way to create one is +to initialize one from a `NSArray` object: + + +```objective-c +#import <RxLibrary/GRXWriter+Immediate.h> + +... + +RTGPoint *point1 = [RTGPoint message]; +point.latitude = 40E7; +point.longitude = -74E7; + +RTGPoint *point2 = [RTGPoint message]; +point.latitude = 40E7; +point.longitude = -74E7; + +GRXWriter *locationsWriter = [GRXWriter writerWithContainer:@[point1, point2]]; + +[client recordRouteWithRequestsWriter:locationsWriter + handler:^(RTGRouteSummary *response, NSError *error) { + if (response) { + NSLog(@"Finished trip with %i points", response.pointCount); + NSLog(@"Passed %i features", response.featureCount); + NSLog(@"Travelled %i meters", response.distance); + NSLog(@"It took %i seconds", response.elapsedTime); + } else { + NSLog(@"RPC error: %@", error); + } +}]; + +``` + +The `GRXWriter` class is generic enough to allow for asynchronous streams, streams of future values, +or even infinite streams. + +Finally, let's look at our bidirectional streaming RPC `RouteChat()`. The way to call a +bidirectional streaming RPC is just a combination of how to call request-streaming RPCs and +response-streaming RPCs. + +```objective-c +[client routeChatWithRequestsWriter:notesWriter + eventHandler:^(BOOL done, RTGRouteNote *note, NSError *error) { + if (note) { + NSLog(@"Got message %@ at %@", note.message, note.location); + } else if (error) { + NSLog(@"RPC error: %@", error); + } + if (done) { + NSLog(@"Chat ended."); + } +}]; +``` + +The semantics for the handler block and the `GRXWriter` argument here are exactly the same as for +our request-streaming and response-streaming methods. Although both client and server will always +get the other's messages in the order they were written, the two streams operate completely +independently. diff --git a/grpc-common/objective-c/route_guide/RouteGuide.podspec b/grpc-common/objective-c/route_guide/RouteGuide.podspec new file mode 100644 index 0000000000..7b99a6c6a7 --- /dev/null +++ b/grpc-common/objective-c/route_guide/RouteGuide.podspec @@ -0,0 +1,35 @@ +Pod::Spec.new do |s| + s.name = "RouteGuide" + s.version = "0.0.1" + s.license = "New BSD" + + s.ios.deployment_target = "6.0" + s.osx.deployment_target = "10.8" + + # Base directory where the .proto files are. + src = "../../protos" + + # Directory where the generated files will be place. + dir = "Pods/" + s.name + + # Run protoc with the Objective-C and gRPC plugins to generate protocol messages and gRPC clients. + s.prepare_command = <<-CMD + mkdir -p #{dir} + protoc -I #{src} --objc_out=#{dir} --objcgrpc_out=#{dir} #{src}/route_guide.proto + CMD + + 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 + ms.dependency "Protobuf", "~> 3.0.0-alpha-3" + end + + 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 + ss.dependency "gRPC", "~> 0.6" + ss.dependency "#{s.name}/Messages" + end +end diff --git a/grpc-common/objective-c/route_guide/RouteGuideClient.xcodeproj/project.pbxproj b/grpc-common/objective-c/route_guide/RouteGuideClient.xcodeproj/project.pbxproj new file mode 100644 index 0000000000..6ab6b27a1b --- /dev/null +++ b/grpc-common/objective-c/route_guide/RouteGuideClient.xcodeproj/project.pbxproj @@ -0,0 +1,366 @@ +// !$*UTF8*$! +{ + archiveVersion = 1;
