Unity 打包IOS平台错误

1、Unity 下打包

Bulid Failed

Assets/Plugins/uLua/x86_64/ulua.dll would be copied to /ulua.dll

Plugin ‘ulua.dll’ is used from several locations:
Assets/Plugins/uLua/x86_64/ulua.dll would be copied to /ulua.dll
Assets/Plugins/uLua/x86/ulua.dll would be copied to /ulua.dll
Please fix plugin settings and try again.

UnityEditor.Modules.DefaultPluginImporterExtension:CheckFileCollisions(String)
UnityEditorInternal.PluginsHelper:CheckFileCollisions(BuildTarget) (at /Users/builduser/buildslave/unity/build/Editor/Mono/Plugins/PluginsHelper.cs:25)
UnityEditor.HostView:OnGUI()

解决：
http://doc.ulua.org/article/faq/pluginuluadllisusedfromserverallocations.html

Plugin ‘ulua.dll’ is used from serveral locations
Assets/Plugins/xxx/ulua.dll would be copied to /ulua.dll 解决方案：

如果是32位Unity编辑器，删掉x86_64目录，如果是64位编辑，删除x86目录即可。

DXT5 compressed textures are not supported when publishing to iPhone

Bulid Success 但仍然有错误，这些问题可能导致游戏闪退

DXT5 compressed textures are not supported when publishing to iPhone
Assets/FX/textures/daoguang/daoguang_00019.dds
Included from scene:
UnityEditor.HostView:OnGUI()

DXT5 纹理压缩时不支持发布iPhone

暂时解决方案：
删除这种纹理贴图

2、Xcode下编译

Signing for “Unity-iPhone” requires a development team. Select a development team in the project editor.

Code signing is required for product type ‘Application’ in SDK ‘iOS 10.3’

原因：
没有在Signing team里面添加签名信息

解决：
xcode7.0开始就可以免证书真机调试
Unity发布至IOS的流程（踩坑记录）
xcode8.2 免证书手机调试详解

ld:’/…/Libraries/Plugins/uLua/iOS/libulua.a(array.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)

‘XXXX’ was compiled with optimization - stepping may behave oddly; variables may not be available

工程在编译之后被优化了，所以导致单步的时候程序表现异常，变量也都不能访问了。这是由于编译的时候选择的是 release，而 release 的时候是会做很多优化，导致上述结果。

解决方法

把编译方式改为Debug。
