ios - IPHONEOS_DEPLOYMENT_TARGET 设置为 8.0 Xcode 12 (Flutter)

Question

我在 Android Studio 中运行我的 Flutter 项目，pod 安装顺利，但每次 Xcode 构建最终都会失败，比如先完成整个构建的 20/30 步。
奇怪的事实是 Android Studio 说:

但是当我用 Xcode 打开工作区时，我看到我在 Runner 中的目标有 iOS deployment target 14.0所以我不明白，它应该设置为 14 但实际上是 8。
Flutter 生成 Podfile , Podfile.lock和 Pods通过 flutter run我更喜欢让 Flutter 在不使用 pod init 的情况下处理 Pod 的生成和安装, pod install或编辑 Podfile .

Answer 1

除了 Akif 所说的之外，这里还有一个运行列表，其中列出了为什么会出现此错误的原因:

设置MinimumOSversion至9.0在 ios/Flutter/AppFrameworkInfo.plist

在 Xcode 中，确保 iOS 部署目标位于 Runner -> Project -> Runner设置为 9.0

在 Xcode 中，确保 Deployment Info在 Runner -> Targets -> Runner设置为 iOS 9.0

仔细检查您的 GoogleService-Info.plist在那里并且是通过 Xcode 添加的(例如，不是通过 Finder 复制/粘贴到目录中)

取消注释 #platform :iOS, '9.0'在您的 ios/Podfile 中添加一行

然后，在您的终端中运行以下命令以使用新状态进行构建:

flutter clean \
        && rm ios/Podfile.lock pubspec.lock \
        && rm -rf ios/Pods ios/Runner.xcworkspace \
        && flutter build ios
