尝试这个，

您可以在 webview 的委托webViewDidFinishLoad方法中尝试这个 java 脚本

NSString *setTextSizeRule = [NSString stringWithFormat:@"addCSSRule('body', '-webkit-text-size-adjust: %d%%;')", currentTextSize];

NSString *changeColor = [NSString stringWithFormat:@"addCSSRule('html, body, div, p, span, a', 'color: #000000;')"];

[webView stringByEvaluatingJavaScriptFromString:setTextSizeRule];
[webView stringByEvaluatingJavaScriptFromString:changeColor];

您可以在 webview 的 done 加载方法中使用 java 脚本进行很多更改。
