ios - React Native 与 Google VR SDK 不兼容

Question

当我尝试添加 Google VR SDK 时，我遇到了 React Native 的问题('GVRSDK') 作为 Podfile 依赖项，并且很容易复制。

步骤:

1. 创建一个新的空白 React Native 项目。使用 react-native run-ios 运行它以确保它有效。
2. cd ios
3. pod 初始化
4. 添加pod 'GVRSDK'到Podfile，执行pod update
5. cd ..
6. react-native run-ios

项目因以下错误而崩溃:

您可以通过删除 libGVRSDK.a 中的重复符号来解决它。 lipo 和ar 命令用于将多个架构中的库文件反汇编并重新归档到另一个文件中。

我制作的shell脚本如下:

pod_post_install.sh

#!/bin/bash

cd ./Pods/GVRSDK/Libraries/
lipo -info libGVRSDK.a

# Divide to each platform
lipo -thin armv7 libGVRSDK.a -output libGVRSDK_armv7
lipo -thin i386 libGVRSDK.a -output libGVRSDK_i386
lipo -thin x86_64 libGVRSDK.a -output libGVRSDK_x86_64
lipo -thin arm64 libGVRSDK.a -output libGVRSDK_arm64

# Delete duplicate file
chmod 777 libGVRSDK_armv7
chmod 777 libGVRSDK_i386
chmod 777 libGVRSDK_x86_64
chmod 777 libGVRSDK_arm64

ar -dv libGVRSDK_armv7 vlog_is_on.o
ar -dv libGVRSDK_i386 vlog_is_on.o
ar -dv libGVRSDK_x86_64 vlog_is_on.o
ar -dv libGVRSDK_arm64 vlog_is_on.o

# rm libGVRSDK.a
lipo -create libGVRSDK_armv7 libGVRSDK_i386 libGVRSDK_x86_64 libGVRSDK_arm64 -output libGVRSDK.a

# Delete media
rm libGVRSDK_armv7
rm libGVRSDK_i386
rm libGVRSDK_x86_64
rm libGVRSDK_arm64

cd ../../../

如果在每个 pod install 运行时调用此脚本，它会更有用。

播客文件

post_install do |installer|
    system(". ./pod_post_install.sh")
end

我相信它会有所帮助。
