导入oc动态库(framework)到C++项目中混编出现的问题

1.Could Not build module 'xxx'

解决：change In target setting the "Allow Non-modular Includes in Framework modules" setting to YES.

2.Use of '@import' when C++ modules are disabled, consider using -fmodules and -fcxx-modul

解决：在target-build settings - Apple Clang - Custom Compiler Flags ，将Other C++ Flags选项debug和release加上-fcxx-modules

3.'string' file not found：

解决：在target-build settings - Apple Clang - Language，将Compile Sources As改为Objective-C++

4. [!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `xxxxxx` to `Target Support Files/Pods-xxxxxx/Pods-xxxxxx.debug.xcconfig` or include the `Target Support Files/Pods-xxxxxx/Pods-xxxxxx.debug.xcconfig` in your build configuration (`ios/UserConfigIOS.debug.xcconfig`).

解决：修改debug.xcconfig文件，增加

#include "../Pods/Target Support Files/Pods-xxxxxx/Pods-xxxxxx.debug.xcconfig"，xxxxx为targets名。

release文件同样方式修改。

 

5. Cannot synthesize weak property in file using manual reference counting

 解决：Weak Reference In Manual Retain Release 改为 YES

6.Xcode fails to build: “Unable to resolve build file: XCBCore.BuildFile”

解决：XCode > Preferences > Locations > Derived Data目录，删除模拟器缓存文件，退出xcode重新打开再编译
