原理：在~/Library/MobileDevice/Provisioning\ Profiles文件夹中删除之前的描述文件，然后系统检测到没有描述文件则会自动生成一个新的
3.打开电脑终端,进入原来embedded.mobileprovision的目录,然后运行命令行:security cms -D -i embedded.mobileprovision
先安装 bundle (bundler.io/) cd 到项目根目录 执行 bundle exe fastlane build 根据提示选择打包哪个target 打包完毕后包会在 桌面（~/Desktop） 目录中
~/Library/Developer/Xcode/Products/

经常遇到从Mac复制之后到ios模拟器上无法粘贴的情况：
解决方案
iOS模拟器–>Edit–>Automatically Sync Pasteboard 选中就可以, 如果不生效, 先取消在选中这也样就解决了
