UIWebView 更改加载内容里面的字体大小

方法一：

1 - (void)webViewDidFinishLoad:(UIWebView *)webView 
2 { 
3     // finished loading, hide the activity indicator in the status bar 
4     [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; 
5     [self.guideWebView stringByEvaluatingJavaScriptFromString:@"document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= ’150%’"]; 
6 }

方法二：

[NSString stringWithFormat:@"<html> \n" 
                                 "<head> \n" 
                                 "<style type=\"text/css\"> \n" 
                                 "body {font-family: \"%@\"; font-size: %f; color: %@;}\n" 
                                 "</style> \n" 
                                 "</head> \n" 
                                 "<body>%@</body> \n" 
                                 "</html>", @"宋体", fontSize,fontColor,stringValue] ;

改变字体颜色

NSString *jsString = [[NSString alloc] initWithFormat:@"document.body.style.fontSize=%f;document.body.style.color=%@",fontSize,fontColor]; 
[webView stringByEvaluatingJavaScriptFromString:jsString];  
[jsString release];
