问题描述

我查看了各种类似的问题和答案，但仍然无法解决这个问题，所以我添加了我自己的问题:

I have looked at various similar questions and answers and still cannot get this to work, so I'm adding my own question:

我正在玩 UIWebView.我可以使用内联 CSS 创建一个工作 html 页面.如果 CSS 在应用资源组的文件中，我无法弄清楚如何加载它.

I'm playing with UIWebView. I can create a working html page with inline CSS. I cannot figure out how to get the CSS to load if it is in a file in the app resources group.

我的代码是:

NSString *path = [[NSBundle mainBundle] pathForResource:@"webViewPage2" ofType:@"html"];
    NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:path];

    NSString *htmlString = [[NSString alloc] initWithData: 
                              [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];


    webView.opaque = NO;
    webView.backgroundColor = [UIColor clearColor];
    [self.webView loadHTMLString:htmlString baseURL:nil];
    [htmlString release];

我的 html 调用是这样的:

And my html call is this:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no, width=device-width">
<link rel="stylesheet" type="text/css" media="only screen and (max-device-width: 480px)" href="/greek123.css" />
</head>

<body style="background-color: transparent;">

<h2>Some Title</h2>


<p>We can put instructions here. Such as: 
"uh-oh You should not have pushed that button!"
</p>


</body>

</html>

如果有任何想法或解决方案，我将不胜感激.非常感谢！

I would appreciate any ideas or solutions. Many thanks!
