ios – React Native Reload和Dev Tools不起作用

概述TL; DR – 我的React Native项目成功运行/渲染.设备震动能力的重装或开发工具无法正常工作. 我在this guide之后的现有项目中设置了React Native.我能够使用以下内容成功呈现我的React Native视图： >在项目根目录中：(JS_DIR = pwd / js; cd node_modules / react-native; npm run start – – TL; DR – 我的React Native项目成功运行/渲染.设备震动能力的重装或开发工具无法正常工作.

我在this guide之后的现有项目中设置了React Native.我能够使用以下内容成功呈现我的React Native视图：

>在项目根目录中：(Js_DIR = pwd / Js; cd node_modules / react-native; npm run start – –root $Js_DIR)
>在Xcode中构建并运行项目

但是,一旦模拟器运行,我就无法使用命令r重新加载JavaScript,也无法使用命令控件z来显示开发人员工具.

我没有使用react-native init< Projectname>创建项目.我正在将React Native添加到现有的Swift项目中.我没有使用react-native run-ios,因为它会抛出以下错误：

我应该寻求什么来重新加载和开发人员工具能力？

解决方法 如果您有自定义配置并且您正在使用Cocoapods,请确保Podfile指定这些配置应该是调试配置.默认情况下,它们被假定为发布配置.将以下行添加到Podfile的顶部(假设您的自定义配置是“Dev”,“Local”和“Staging”)：

对于1.0之前的Cocoapods使用xcodeproj：

xcodeproj 'MyProject','Dev' => :deBUG,'Local' => :deBUG,'Staging' => :deBUG

对于Cocoapods 1.0使用project：

project 'MyProject','Staging' => :deBUG

然后,要更新Pods.xcodeproj文件：

rm -rf Pods/pod install

这将确保为Pods项目的那些配置设置DEBUG = 1预处理器宏.
