                  问题描述

                  我想为桌面设计一个网页样式,以便它可以在 iPhone 上的 UIWebView 上显示.我无权访问页面来源的 Web 服务器.我想通过以编程方式更改 <link> 样式表元素的 href 属性来做到这一点.

                  I want to style a web page meant for the desktop so that it is presentable on a UIWebView on iPhone. I do not have access to the web server from which the pages originate. I would like to do this by changing the href attribute of the <link> stylesheet element programmatically.

                  我使用 IBOutlet UIWebView *webView 执行以下操作.

                  I do the following with my IBOutlet UIWebView *webView.

                  NSString *cssPath = [[NSBundle mainBundle] pathForResource:@"MyStyleSheet" 
                                                                      ofType:@"css"];
                  NSString *js = @"document.getElementsByTagName('link').setAttribute('href','";
                  NSString *js2 = [js stringByAppendingString:cssPath];
                  NSString *finalJS = [js2 stringByAppendingString:@"');"];
                  
                  //check element structure
                  NSString *res = [webView stringByEvaluatingJavaScriptFromString:finalJS]; 
                  

                  这不起作用.使用 [webView stringByEvaluatingJavaScriptFromString:] 消息并更改正文的 backgroundColor 确实有效 - 作为练习来查看我是否正确使用了调用.

                  This does not work. Using the [webView stringByEvaluatingJavaScriptFromString:] message and making a change to the backgroundColor of the body does indeed work - done as an exercise to see if I was using the call correctly.

                  我是不是找错树了?

                  推荐答案

                  可以从本地项目目录加载CSS

                  You can load CSS from local project directory

                  NSString *path = [[NSBundle mainBundle] bundlePath];
                  NSURL *baseURL = [NSURL fileURLWithPath:path];
                  [webView loadHTMLString:htmlString baseURL:baseURL];
