其他备份
If you need to have libxml2 first in your PATH run:

echo 'export PATH="/usr/local/opt/libxml2/bin:$PATH"' >> ~/.bash_profile
For compilers to find libxml2 you may need to set:
export LDFLAGS="-L/usr/local/opt/libxml2/lib"
export CPPFLAGS="-I/usr/local/opt/libxml2/include"
For pkg-config to find libxml2 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig”
4.打开ios模拟器
open -a Simulator
5.安装其他命令
brew install --HEAD libimobiledevice
brew install ideviceinstaller ios-deploy cocoapods
pod setup
6.用android stuodio创建一个demo运行效果如下
