react-native-motion-manager 安装AccelerometerGyroscopeMagnetomer 介绍
react-native-motion-manager 是 CMMotionManager 对 react-native 的封装， 是 React
Native 的动力传感器（加速计，陀螺计，磁力计）组件。
添加到你的项目：
-
npm install react-native-motion-manager@latest --save
-
在 XCode 的项目导航右击 Libraries ➜ Add Files to [your project's name]
-
转到 node_modules ➜ react-native-motion-manager 然后添加 RNMotionManager.xcodeproj
-
在 XCode 项目导航选择你的项目，添加 libRNMotionManager.a 到你项目的 Build Phases ➜ Link Binary With Libraries
-
在项目导航中点击 RNMotionManager.xcodeproj 然后转向 Build Settings 标签。确保 ‘All’ 勾选上 (替代 ‘Basic’)。查看 Header Search Paths 确保它包括 $(SRCROOT)/../react-native/React 和 $(SRCROOT)/../../React - ，把两个都标记为 recursive
-
运行你的项目 (Cmd+R)
