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:

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

改变字体颜色

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