ios - 为 iOS 编译时出现 UniWebView 链接器错误(使用 Unity 5、XCode 7.3.1 和 iOS SDK 9.3)

Question

我在跨平台应用程序中使用 UniWebView 2，虽然该应用程序在 Android 上编译和运行，但在为 iOS 构建它时，我在 XCode 中构建项目时遇到错误。我尝试创建一个空项目并编译 UniWebView 示例场景之一，但遇到了同样的错误。

报错如下:

• 我保留了 Plugins 目录结构
• 我使用 IL2CPP 作为脚本后端
• 我的目标是正确的设备、SDK 和 iOS 版本
• 我已尝试在 XCode 项目设置中禁用 bitcode 并启用 Preserve Private External Symbols

• 我设法在 iPad 模拟器上构建和部署(x86_64，因为我是在 64 位 Mac 上构建的)

• Here是定义相关方法的 WebViewObject.cs 文件

感谢您的宝贵时间。

WebViewPlugin是Gree的unity web view，所以应该不是UniWebView的问题(他们是不同的包)。

如果您不使用 WebViewPlugin 和相关的东西，您可以尝试从您的项目中删除它们。并仅使用 UniWebView 再试一次。
