使用React Native打开iOS iPad模拟器

Question

使用react-native run-ios它测试React Native应用程序时会打开一个iPhone模拟器.

您可以在Simulator选项中将虚拟设备更改为iPad,但React Native应用程序不会出现在已安装的应用程序列表中.

有没有办法从CLI打开iPad模拟器？

Answer 1

--simulator flag正是你要找的

例如,react-native run-ios --simulator 'iPad 2'将在iPad 2模拟器上运行该应用程序.

作为侧节点,如果您需要获取名称使用的可用模拟器列表 xcrun simctl list devices

Answer 2

使用此命令获取设备列表

xcrun simctl list devices
