UIWebView和本地css文件 [英] UIWebView and local css file

问题描述

我想为桌面设计一个网页样式，以便在iPhone上的UIWebView上显示。我无法访问该页面源自的Web服务器。我想通过以编程方式更改< link> stylesheet元素的 href 属性来实现。

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。

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：] 消息并更改主体的 backgroundColor

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.

我是咆哮错误的树吗？

推荐答案

您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];
