经过长时间的研究，我的问题终于得到了答案

- (void)webViewDidFinishLoad:(UIWebView *)webView{
[self stopProgressHUD];
NSString *cssString = [[[[@"body { font-family:" stringByAppendingString:centuryGothicRegular] stringByAppendingString:@"; font-size:"] stringByAppendingString:[NSString stringWithFormat:@"%ld",normalFont]] stringByAppendingString:@"}\""] ; //1

NSString *javascriptString = @"var style = document.createElement('style'); style.innerHTML = '%@'; document.head.appendChild(style)"; // 2
NSString *javascriptWithCSSString = [NSString stringWithFormat:javascriptString, cssString]; // 3
NSLog(@"javascriptWithCSSString: \n %@", javascriptWithCSSString);
NSString *loadedContent = [webView stringByEvaluatingJavaScriptFromString:javascriptWithCSSString];
NSLog(@"loaded ocntent: %@", loadedContent);

}

centuryGothicRegular 是声明为常量的字体名称。 normalFont 是字体大小，也声明为整数常量
