iOS 上的 Firebase 应用检查在构建时崩溃答案

【发布时间】：2021-12-29 19:17:54
【问题描述】：

在我添加包firebase_app_check: ^0.0.3之前，每个想法都运行良好

该应用在构建项目时崩溃，无法在 iOS 上运行，但在 Android 上运行良好。

Andoird 应用可以连接到 firebase，但是 iOS 不能这样做，因为请求没有经过身份验证。

颤振：2.5.2

【解决方案1】：

将platform :ios, '11.0' 添加到 Podfile。

AppCheckrequires iOS 11.

【解决方案2】：

我认为，您的 CocoaPods 设置将会崩溃。因为 firebaseAppcheck 版本问题。您将不得不手动删除 Specs 存储库的任何本地副本并重新克隆 Specs 存储库的新版本。您可以使用以下命令执行此操作：

在终端执行以下命令即可解决。

1. Go to /ios folder inside your Project.
2. Delete Podfile.lock (YourPoject/ios/Podfile.lock)
3. Delete Project.Workspace file.
3. Run pod install --repo-update (Make sure your cd into the iOS directory of the flutter app)
4. Run flutter clean
5. Once complete, rebuild your Flutter application: flutter run

如果上述步骤不适用于您的项目。你也可以试试这个：

 1. change the higher minimum deployment target (at least 11). 
 2. Just Follow the above steps.
