一.先在码云创建一个项目不做介绍 二.生成ssh公钥和私钥 开始菜单搜索PuTTYgen并打开 点击Generate开始生成 然后鼠标在上方的空白区域随便乱晃,直到生成好为止 保存私钥,点击下方的Save private key 将私钥保存到任意一个位置这个文件等下要用到 保存公钥,将上方方框中的公钥全部复制下来到一个文本文件中,等下会用到 三.在码云设置上公钥 点击个人图标选择设置,进入个人设置界面 点击左侧安全设置下的 “SSH公钥” 复制公钥到码云,并设置公钥标题,标题随便填一下吧 我写的是 “SSH” 将第二部生成的公钥复制到码云中 四.设置本地Git 选择一个文件夹作为项目文件夹 在项目文件夹上右击选择 “在这里创建版本库”,然后点击确认即可 在文件夹中右击选择TortoiseGit->设置 设置远端 选择Git下的远端选项 分别填入如下类容 远端: 随便起一个名字,我这边是和项目名相同 Url 项目的ssh (码云中进入项目 选择克隆下载中的ssh地址) 推送URl: 和上方的Url相同即可 putty秘钥: 选择第二步操作中的私钥 最好点击下方的添加保存即可 五.推送项目 右击Git提交,选择需要推送的文件 选择提交并推送 点击提交并推送之后会弹出一个新窗口 请勾选 “已知变更” 因为是首次提交,不勾选可能会出现错误,以后推送的时候就不需要勾选这个选项了 点击确定,即可推送完成

使用unity打包成ios项目时 如果unity项目中使用了反射基本上就会有问题 ios这边不支持反射 所以一些常用的C#的反射库还是不要使用了 如果一定要使用某些反射的库 一定要仔细查询一下这个库是否支持ios

在对应的项目上右击属性->生成事件->生成后事件 命令行中添加以下命令,则自动复制头文件到对应的项目目录下,这样就无需通过手动去复制头文件的方式引用静态库 xcopy ".\*.h" "..\RegCenter" /s /h /d /y
