objective-c - IOS webView获取js脚本文件的url

Question

如上图片显示，我想在webView加载这个Html文件的时候，能获取js文件的外部链接，比如：当我监控到<script src="http:///localpath/jquery-1.8.3.min.js"></script>这个地址被调用时，我替换地址调用本地脚本文件。
现在我想问：
1.这样可以实现吗？
2.我如何监控webView调用js细节，比如我再webView的代理方法里可以监控webView调用了某个URL

Answer 1

1. This can be achieved
2. The specific principle is actually loading monitoring and dynamic replacement when loading a web page. There is currently a library that implements this functionality. The library is very old~ but you can use specific js cache or dynamic replacement

If you have any problems during use, you can contact me~
