iOS TRTC SDK 编译问题解决办法

1、Bitcode 报错

错误信息：

Pods/TXLiteAVSDK_Professional/TXLiteAVSDK_Professional/TXLiteAVSDK_Professional.framework/TXLiteAVSDK_Professional(dict.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. for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方法：

在项目的target的 Build Setting 里面，搜素bitcode，把 Enable Bitcode设置成NO。

2、缺少依赖库

错误信息片段如下：

解决方案：

引入如下库：

libz.tbd
libc++.tbd
libresolv.tbd
libsqlite3.tbd
Accelerate.framework
OpenAL.framework

引入步骤：

3、xxx file not found（Objective-C报错信息）

No such module 'TXLiteAVSDK_TRTC'（Swift报错信息）

检查一下search patch 相关的设置，看看路径是否

设置Framework 路径如下：

另外Header等的路径也确保没有出现错误。

4、Objective-C和Swift混编引起的问题

Swift引用OC代码，需要创建bridge文件，把OC文件引入

OC引用Swift代码，需要在OC文件中引入 '项目名-Swift.h'，同时把Swift类设置成public，方法和属性前面添加@Objc

5、符号冲突

错误信息：

duplicate symbol xxx

把 other linker flags 需要设置成-Objc

-Objc：加载OC代码

-all_load，-force_load 加载全部代码

6、8.0版本的SDK，缺少replaykit库

错误信息

Undefined symbols for architecture arm64:

"_RPVideoSampleOrientationKey", referenced from:

-[TXCReplayKitExtVideoEncoder rotationOfSampleBuffer:imageWidth:imageHeight:] in TXLiteAVSDK_ReplayKitExt(TXCReplayKitExtVideoEncoder.o)

"_OBJC_CLASS_$_RPScreenRecorder", referenced from:

objc-class-ref in TXLiteAVSDK_Professional(TXCCaptureAndEnc.o)

objc-class-ref in TXLiteAVSDK_TRTC(TXCCaptureAndEnc.o)

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方案：

引入 ReplayKit.framework。
