当同时导入Leancloud最新插件和Unity自带的IAP插件时出现如下问题：
error CS1704: An assembly with the same name `UnityEditor.iOS.Extensions.Xcode' has already been imported. Consider removing one of the references or sign the assembly
Assets/LeanCloud/UnityEditor.iOS.Extensions.Xcode.dll (Location of the symbol related to previous error)
/Applications/Unity/PlaybackEngines/iOSSupport/UnityEditor.iOS.Extensions.Xcode.dll (Location of the symbol related to previous error)

Compilation failed: 1 error(s), 0 warnings

我去查了下,在/Applications/Unity/PlaybackEngines/iOSSupportxia这个文件夹下已经有了UnityEditor.iOS.Extensions.Xcode.dll。
之后把插件中的UnityEditor.iOS.Extensions.Xcode.dll删掉，编译通过，运行时又出现下面错误：

请问这个问题要怎样解决？（用的mac版的Unity）
谢谢

导入的这6个dll.

请问具体怎样操作呢？我用/Applications/Unity/Unity.app/Contents/UnityExtensions/Unity/Advertisements/Editor/UnityEditor.iOS.Extensions.Xcode.dll这个替换掉插件里的dll，运行时还是有错误啊？

5.5.2f1

有没有导入Unity IAP的包？
不导入这个包可以运行。
导入IAP包并且替换dll之后运行时出现这个问题：

新建的项目也是这样的

LeanCloudTest.zip6 (2.0 MB) 好的,里面的UnityEditor.iOS.Extensions.Xcode.dll已经被我替换掉了
