ProtocolBuf Swift 使用

环境搭建

Mac安装swift-protobuf

brew install swift-protobuf

复制

使用Podfile集成Xcode

再Podfile里添加

pod 'SwiftProtobuf'

复制

然后在此目录下打开terminal运行

Pod install

复制

使用

新建BookInfo.proto

syntax = "proto3";

message BookInfo {
   int64 id = 1;
   string title = 2;
   string author = 3;
}

复制

在此文件同目录下执行下面命令，生成.swift文件

protoc --swift_out=. BookInfo.proto

复制

将.swift文件拖入工程，编译一下，使用

// Create a BookInfo object and populate it:
var info = BookInfo()
info.id = 1734
info.title = "Really Interesting Book"
info.author = "Jane Smith"

do {
    // Serialize to binary protobuf format:
    let binaryData: Data = try info.serializedData()

    // Deserialize a received Data object from `binaryData`
    let decodedInfo = try BookInfo(serializedData: binaryData)

    // Serialize to JSON format as a Data object
    let jsonData: Data = try info.jsonUTF8Data()

    // Deserialize from JSON format from `jsonData`
    let receivedFromJSON = try BookInfo(jsonUTF8Data: jsonData)
} catch {
    print(error)
