ios 修改webView字体

 UIFont *font = [UIFont systemFontOfSize:];

    //方法一

    NSString *fontColor =@"CCCCFF";

    NSString *htmlString =[NSString stringWithFormat:@"<html> \n"

                        "<head> \n"

                        "<style type=\"text/css\"> \n"

                        "body {font-family: \"%@\"; color: %@;}\n"

                        "</style> \n"

                        "</head> \n"

                        "<body>%@</body> \n"

                        "</html>", font.familyName,fontColor,self.html];

    //方法二

   NSString* htmlString = [NSString stringWithFormat:@"<span style=\"font-family: %@!important; font-size: %i\">%@</span>",

                  font.fontName,

                  (int) font.pointSize,

                  self.html];

    //方法三

    NSString *htmlString = [NSString stringWithFormat:@"<font face='%@' >%@", font.fontName,self.html];

   //以上三种方法都需 提起获取到 html,然后用下面方法加载html

    [self loadHTMLString:htmlString baseURL:DDWebBaseURL];

//方法4 也可以在webview中代理方法中修改  这种方法体验不好

- (void)webViewDidFinishLoad:(UIWebView *)webView {
      UIFont *font = [UIFont systemFontOfSize:14];        
      NSString *script = [NSString stringWithFormat:@"document.body.style.fontFamily = '%@'",font.familyName];
     [webView stringByEvaluatingJavaScriptFromString:script];

}
//通过修改DOM,修改特定节点的样式

NSString *script1 = @"document.getElementsByClassName('component-item component-content')[0].getElementsByTagName('p')[0].style.fontSize='30px'";

NSString *script = @"document.getElementsByClassName('component-item component-content')[0].getElementsByTagName('p')[0].style.fontFamily='DFWaWaW5'";

NSString *html341 =[webView stringByEvaluatingJavaScriptFromString:script1];

NSString *html34 =[webView stringByEvaluatingJavaScriptFromString:script];
