- 1.在iOS模擬器中無法調用Command+R進行刷新
分析： 將模擬器的操作關閉了
解決辦法：將模擬器中國Hardware->Keyboard->Connect Hardware Keyboard打開即可

報錯
原因：init命令默認會創建最新的版本，而目前最新的0.45版本需要下載boost庫編譯。此庫體積龐大，在國內即便翻墻也很難下載成功，導致很多人無法正常運行iOS項目，推薦暫時使用0.44.3的版本。
解決辦法： 創建項目暫時先使用react-native init MyApp --version 0.44.3，指定某個版本。
你可以使用--version參數（注意是兩個杠）創建指定版本的項目。例如react-native init MyApp --version 0.44.3。注意版本號必須精確到兩個小數點。
