你可以尝试这样的事情:

    NSString *varMySheet = @"var mySheet = document.styleSheets[0];";

NSString *addCSSRule =  @"function addCSSRule(selector, newRule) {"
"if (mySheet.addRule) {"
    "mySheet.addRule(selector, newRule);"                               // For Internet Explorer
"} else {"
    "ruleIndex = mySheet.cssRules.length;"
    "mySheet.insertRule(selector + '{' + newRule + ';}', ruleIndex);"   // For Firefox, Chrome, etc.
"}"
"}";

    // NSLog(@"w:%f h:%f", webView.bounds.size.width, webView.bounds.size.height);

NSString *insertRule1 = [NSString stringWithFormat:@"addCSSRule('html', 'padding: 0px; height: %fpx; -webkit-column-gap: 0px; -webkit-column-width: %fpx;')", webView.frame.size.height, webView.frame.size.width];
NSString *insertRule2 = [NSString stringWithFormat:@"addCSSRule('p', 'text-align: justify;')"];
NSString *setTextSizeRule = [NSString stringWithFormat:@"addCSSRule('body', '-webkit-text-size-adjust: %d%%;')",fontPercentSize];
