在用 appium 做 iOS 混合 APP 自动化时，碰到了无法获取 webView 上下文的问题，参考社区中http://testerhome.com/topics/10951###的帖子，依然未解决问题，仍然只能获取到 Native,麻烦大佬们给个指点

iOS 版本 15.1

Appium 版本 1.21.0

你有用 ios-webkit- debug- proxy 这个工具吗？

检查下 iOS safari 的设置，有没有按照参考贴楼主的提示启用Web Inspector（也可以参考https://webkit.org/web-inspector/enabling-web-inspector/#ios-device）
使用 Mac Safari/Safari Technology Preview 检查下有没有 webview context
ios-webkit-debugger-proxy 对于 appium > 1.15 不是必须的，> 1.15 的，安装 appium-ios-device 试试（https://appium.io/docs/en/writing-running-appium/web/hybrid/index.html）
webview 的加载很多时候需要时间，加个等待试试
调试下 webview 相关的参数，参考：http://appium.io/docs/en/writing-running-appium/caps
另外就是支持的 webview 类型了: Appium can automate WkWebView and UIWebView elements. Unfortunately, it is not currently able to handle SafariViewController elements
