QT On IOS + protobuf3的使用

如果你看到了这个，并且你还有在android上面使用的需求，请看我另外一篇博文。

因为需要用到，确实也百度和谷歌找了很多，基本没什么关于protobuf3+QT的使用的，大部分都是讲protobuf2.6的。功夫不负有心人，终于搞定了protobuf3+qt的使用。

1、编写编译脚本

该脚本源自于git，点击前往git

如果直接使用该脚本，则可以生成protobuf2.6的，可以使用。

如果要想生成protobuf3的，则需要修改一些地方。

需要修改的地方为

使用方法就是，新建一个文件夹，把上面的代码赋值到 xxx.sh文件中去，然后添加权限，然后执行即可。
注意安装必要的依赖库，比如执行语句 

brew install autoconf automake libtool curl make g++ unzip

2、在QT中的使用办法：
与调用普通库一样的，例如

ios:{CONFIG -= bitcode       INCLUDEPATH += /Users/macos/mylibs/protobuf/include       LIBS += -L/Users/macos/mylibs/protobuf/platform/universal \-lprotobuf}

注意，其中有一条很重要，
CONFIG -= bitcode
这一句是必须的，这都是百度谷歌很多次，才在一个角落里面发现的。
