React Native FBSDK无法识别的选择器发送到实例答案

【问题标题】：React Native FBSDK unrecognized selector sent to instanceReact Native FBSDK无法识别的选择器发送到实例
【发布时间】：2016-12-29 07:20:04
【问题描述】：

我正在尝试让 react-native FBSDK 工作。具有讽刺意味的是，之前没有任何更改的相同代码（我什至有登录工作的屏幕记录）但是自从重新启动 xcode 和模拟器后，我在应用启动时收到了这个崩溃。

我仔细检查以确保我正确执行了安装步骤。我还用 cocoapods 切换了手动下载的版本，但同样的错误

【问题讨论】：

重启模拟器或在另一个模拟器中运行代码
@KAR 果然，切换模拟器或重置现有模拟器确实有效，但导致此问题的原因是什么，我该如何避免遇到它？实际设备是否有可能发生这种情况？
这是模拟器导致的错误。我认为模拟器中存在一些错误。
或在模拟器中重新安装应用

【解决方案1】：

我认为您错过了在应用的 Info.plist 中添加这些内容。

<key>FacebookAppID</key>
<string>Your_App_ID</string>
<key>FacebookDisplayName</key>
<string>Your_App_Display_Name</string>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-share-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

【解决方案2】：

对我来说，因为我使用 cocoapods 进行链接，删除手动链接解决了这个问题。

也就是说，转到 Xcode > Project Root > Build Phases > Link Binary with Libraries 并删除 Facebook Core/Login 等。
