                  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!

                  推荐答案

                  将 UIWebView 的 baseURL 更改为 mainbundle 的 url.

                  change the baseURL of the UIWebView to the url of your mainbundle.

                  NSURL *mainBundleURL = [[NSBundle mainBundle] bundleURL];
                  [self.webView loadHTMLString:htmlString baseURL:mainBundleURL];
                  

                  斯威夫特 3:

                  webView.loadHTMLString(contentString, baseURL: Bundle.main.bundleURL)
