介紹

本系列是SDK打包的實(shí)踐，主要解決一下3個(gè)問(wèn)題，本篇是第一篇。
【iOS開(kāi)發(fā)】SDK開(kāi)發(fā)之編譯c/c++
【iOS開(kāi)發(fā)】SDK開(kāi)發(fā)之podspec編寫(xiě)
【iOS開(kāi)發(fā)】SDK開(kāi)發(fā)之podspec內(nèi)執(zhí)行腳本

本期問(wèn)題

SDK的源碼是由其他團(tuán)隊(duì)編寫(xiě)，使用的語(yǔ)言為c/c++，且會(huì)依賴(lài)第三方的庫(kù)(也是c/c++編寫(xiě))。
考慮有以下幾種方案：1 Xcode編譯 2 cmake編譯

一 Xcode編譯步驟

1 使用Xcode創(chuàng)建Framework項(xiàng)目

2 添加所有使用的c/c++文件（依賴(lài)的第三方的文件）
3 調(diào)整暴露的頭文件public headers
4 編譯（command+B）

優(yōu)點(diǎn)：
Xcode原生IDE加持，可視化好，操作簡(jiǎn)單
缺點(diǎn)：
1 需要運(yùn)行在mac電腦上（iOS開(kāi)發(fā)肯定有mac電腦，but如果需要編寫(xiě)團(tuán)隊(duì)來(lái)編譯就不行了，因?yàn)樗麄兪莑inux環(huán)境）
2 第三方依賴(lài)需要我們手動(dòng)配置（尤其在依賴(lài)文件有變化的時(shí)候，需要跨團(tuán)隊(duì)溝通）

二 cmake編譯步驟

1 編寫(xiě)cmake腳本
2 執(zhí)行cmake腳本

優(yōu)點(diǎn)：
1 運(yùn)行在任何有cmake環(huán)境的電腦（linux/mac均可）
2 cmake支持嵌套，直接嵌套使用編寫(xiě)團(tuán)隊(duì)使用的cmake
3 腳本編寫(xiě)簡(jiǎn)單，維護(hù)成本低
4 可接CI/CD

最后附上打包SDK的cmake(嵌套的cmake就不貼了)
