- 1.在iOS模拟器中无法调用Command+R进行刷新
分析： 将模拟器的操作关闭了
解决办法：将模拟器中国Hardware->Keyboard->Connect Hardware Keyboard打开即可

报错
原因：init命令默认会创建最新的版本，而目前最新的0.45版本需要下载boost库编译。此库体积庞大，在国内即便翻墙也很难下载成功，导致很多人无法正常运行iOS项目，推荐暂时使用0.44.3的版本。
解决办法： 创建项目暂时先使用react-native init MyApp --version 0.44.3，指定某个版本。
你可以使用--version参数（注意是两个杠）创建指定版本的项目。例如react-native init MyApp --version 0.44.3。注意版本号必须精确到两个小数点。
