使用Facebook SDK后，反应原生IOS应用程序中的链接错误

Question

我正在使用 RNFirebase.io 并尝试它的入门套件。它确实工作正常，但在设置 Facebook SDK 后我开始收到以下这些错误。

ld: warning: Auto-Linking supplied '/Users/xyz/Documents/FacebookSDK/FBSDKLoginKit.framework/FBSDKLoginKit', framework linker option at /Users/xyz/Documents/FacebookSDK/FBSDKLoginKit.framework/FBSDKLoginKit is not a dylib

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已经尝试过的解决方案 -1. 在构建设置部分的"框架搜索路径"中添加了"~/文档/FacebookSDK"。2. 还检查了 libRCTFBSDK.a 是否添加到"链接二进制文件与库"中

我应该怎么做才能解决它？

Answer 1

我遇到了同样的问题，解决方案非常简单，但解决方案并没有忘记..

我们走吧。

使用此步骤 iOS 指南

但在第 7 步。

通过在项目的根文件夹的命令提示符下执行以下命令来安装文件ios_setup.js。

我建议您输入原始iOS安装脚本

在根iOS文件夹中的终端上使用。

六 ios_setup.js

和粘贴

 A node script to help set up FBSDK frameworks for use with https://github.com/facebook/react-native-fbsdk

 1. add to the 'script' section in package.json of your react-native project the following:

之后，执行脚本

node ios_setup.js 'fb_id_here' 'fb_app_name_here'
