我已将 BurstlySDK 和 TestFlightSDK 添加到我的项目中，但出现以下链接器错误：

duplicate symbol _OBJC_CLASS_$_TFApplicationInformation in:
/Users/Andrey/Documents/Helicopter/helicopter_clone/HelicopterClone/BurstlySDK/libBurstly.a(TFApplicationInformation.o)
/Users/Andrey/Documents/Helicopter/helicopter_clone/HelicopterClone/TestFlightSDK2/libTestFlight.a(TFApplicationInformation.o)

引用TFApplicationInformation的只是一个例子。错误消息中提到了大约十个带有 TF 前缀的类。任何人都可以解释为什么会这样吗？谢谢

由于 TestFlight SDK 与 SkyRocket SDK 捆绑在一起，因此您无需在 libTestFlight.a 中进行链接，但您需要将 TestFlight.h 保留在您的项目中，并在需要使用 TestFlight 功能时将该标头导入到类中。如果您没有 TestFlight.h（它应该与 TestFlight SDK 完全捆绑在一起），您可以在此处下载 TestFlight SDK：https ://testflightapp.com/sdk/download/

来自 Burslty iOS 集成指南：

Note: The TestFlight SDK has been bundled with SkyRocket since 2.X

正如上面 Alex M 所建议的那样，Burstly 支持建议删除 libTestFlight.a，但这让我感到紧张，因为我感觉到 Burstly 将更多资源用于维护 TestFlight SDK 而不是 SkyRocket SDK。诚然，这种直觉可能是我的想象，但我无法摆脱它。

所以，我写了这个脚本。它从 libBurstly.a 中去除重复的符号并输出一个 libBurstly-noTestFlight.a，它可以无冲突地链接。对于我当前的项目，路径是硬编码的，所以如果你想使用它，你必须为你自己的项目调整脚本。

#!/bin/bash

# I install this script as $(SRCROOT)/scripts/strip_tf_duplicate_symbols, and 
# run it from $(SRCROOT).  
# It looks for libBurstly.a under $(SRCROOT)/Vendors/BurstlySDK.
# Sorry about the hard-coded paths.  I didn't design this to be used in other projects.

if [ -d ./Vendors/BurstlySDK ]
then
    echo "Preparing to strip duplicate symbols from libBurstly.a..."
else
    echo "Creates Vendors/BurstlySDK/libBurstly-noTestFlight.a with duplicate symbols removed."
    echo "Usage: run ./scripts/strip_tf_duplicate_symbols from the Xcode project root"
    exit
fi
