我想更改 HTML 文档中背景图像属性的 URL。
DOMCSSStyleDeclaration *style = domELement.style;
NSString *imageURL = [style backgroundImage];
现在 imageURL 看起来像 url(/image.jpg)。但在 HTML 源代码中它是 url(image.jpg)。
现在我想将 image.jpg 更改为其他图像并仍然保留相对路径。我该怎么做？因为当我设置类似 url(newImage.jpg) 的内容时，渲染的输出看起来像 url(/newImage.jpg) 。
获取 HTML 时我可以更改一些内容吗？
DOMHTMLElement *htmlElement = (DOMHTMLElement*)[document documentElement];
NSString *html = [htmlElement outerHTML];
或者有其他方法可以在 css 属性中设置相对 URL 吗？
[style setBackgroundImage:@"url(newImage.jpg)"];
I want to change the URL's of a background-image property in a HTML document.
DOMCSSStyleDeclaration *style = domELement.style;
NSString *imageURL = [style backgroundImage];
Now the imageURL looks something like url(<base URL I've loaded the HTML with>/image.jpg). But in the HTML source it's url(image.jpg).
Now I'd like to change the image.jpg to an other image and still keep the relative path. How do I do that? Because when i set something like url(newImage.jpg) the rendered output looks like url(<base URL I've loaded the HTML with>/newImage.jpg).
May I change something when getting the HTML?
DOMHTMLElement *htmlElement = (DOMHTMLElement*)[document documentElement];
NSString *html = [htmlElement outerHTML];
Or is there an other way how I can set a relative URL in a css attribute?
[style setBackgroundImage:@"url(newImage.jpg)"];

我根本没有发现任何东西。所以我自己用 NSSCanner 解析了它
