UIWebView获取HTML源代码 [英] UIWebView get HTML Source

问题描述

我正在尝试获取UIWebView的HTML源代码，而无需再次重新下载它（也可以进行其他下载，例如 [NSData dataWithContentsOfURL：（NSURL *）URL] 或启动一个NSURLRequest浏览UIWebView头文件，似乎没有办法访问当前加载的NSData的源代码，我错过了什么？

I am trying to get the HTML source of a UIWebView without re-downloading it again (a.k.a. do another download, such as [NSData dataWithContentsOfURL:(NSURL*)URL] or launching an NSURLRequest. Browsing the UIWebView header and documentation, there seems to be no way of accessing the current loaded NSData of the source. Am I missing something ?
