WebView 和 RN 通信只能靠极其有限的手段:RN 可以通过 injectJavaScript 向 WebView 内部注入 JS 代码 (string),注入时会立即执行;反之,WebView 内部可以通过调用 window.ReactNativeWebView.postMessage 向 RN 发送消息 (string), RN 通过监听 onMessage 获取到相应的信息。
onLoadProgress={e => console.log(e.nativeEvent.progress)} /> ); } } ``` 如果出现如下报错: >Invariant Violation: requireNativeComponent: "RNCWKWebView" was not found in the UIManager 解决方案: ###1.将RNCWebView.xcodeproj添加到项目的Libraries中, ...
