Flutter构建IOS位码问题，如何修复位码错误

Question

我尝试在连接手机的情况下构建iOS或者运行"flutter build ios"命令时，出现了以下错误：

ld: '/Users/Library/Developer/Xcode/DerivedData/Runner-dwvxvkkosgpgqncynmszqlholtde/Build/Products/Debug-iphoneos/BoringSSL-GRPC/libBoringSSL-GRPC.a(BoringSSL-GRPC-dummy.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/Library/Developer/Xcode/DerivedData/Runner-dwvxvkkosgpgqncynmszqlholtde/Build/Products/Debug-iphoneos/BoringSSL-GRPC/libBoringSSL-GRPC.a' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如果我使用模拟器运行，它能够正常工作，但是当连接实体设备或者进行Flutter构建时就出现了问题，如何解决？

安装一个依赖于位码的库后，我也遇到了类似的问题。请像图片中一样，在项目“Pods”所有目标中更改启用位码。

这个对我有用。我认为这应该是被接受的答案。 - filiph

每次我想要构建时都必须这样做。一定有更好的方法来做这件事并让它记住。有什么想法吗？ - Drew Bartlett

首先，如果您使用的库默认启用了位码，则无需一次又一次地设置它，这样会很方便。是的，这很令人沮丧，但Flutter目前不支持位码，所以我找到的唯一更好的方法是避免使用需要位码的库。我在项目中删除了需要位码的扩展名，并使用了自己的实现，这样我就不必再经历这些麻烦了。这是我找到的更好的方法。 - Alish Giri

将启用的位码从YES更改为NO解决了我的问题。 - sanyam jain
