如何在UIWebview中的目录（js，images，css）中加载本地html资源？ （IOS） [英] How to load local html assets in directories (js, images, css) in a UIWebview? (iOS)

问题描述

具体来说 - 如何在不更改原始HTML（删除目录）的内容的情况下从各自的目录（images /，css /，js /）中加载所有资源？

我使用此代码将index.html加载到UIWebview中：

  NSURL * url = [ [NSBundle mainBundle] URLForResource：@indexwithExtension：@html]; 
 NSString * html = [NSString stringWithContentsOfURL：url encoding：NSUTF8StringEncoding error：nil]; 
 
 NSString * path = [[NSBundle mainBundle] bundlePath]; 
 NSURL * baseURL = [NSURL fileURLWithPath：path]; 
 
 [webView loadHTMLString：html baseURL：baseURL]; 
  

然后我的html看起来像这样：

  ... 
< link rel =stylesheettype =text / csshref =css / main.css/> 
< script type =text / javascriptsrc =js / classes.js>< / script> 
< script type =text / javascriptsrc =js / animate.js>< / script> 
等... 
  

如果我删除了js /，css /和images /一切正常，因为iOS认为一切都在我的包的根目录中。但是，这意味着我无法跨项目使用相同的代码，而无需将其全部转储到一个目录中（跛脚）。我的工程师无法应对这种混乱。

提前致谢。

解决方案

简单：当您将文件夹添加到Xcode时，请确保将它们添加为文件夹引用。

<然后将它们作为文件夹添加到.app包中：

Specifically -- how do you get all the assets to load from their respective directories (images/, css/, js/) without changing the content of the original HTML (removing directories)?

I am using this code to load index.html into the UIWebview:

NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"];
NSString *html = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];

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

[webView loadHTMLString:html baseURL:baseURL];

Then my html looks like this:

...
<link rel="stylesheet" type="text/css" href="css/main.css" />
<script type="text/javascript" src="js/classes.js"></script>
<script type="text/javascript" src="js/animate.js"></script>
etc...

If I remove the js/, css/, and images/, everything works because iOS thinks everything is in the root of my bundle. But, that means I cant use the same code across projects without dumping it all into one directory (lame). The engineer in me can't deal with this kind of disorganization.

Thanks in advance.

解决方案

Easy: when you add the folder(s) to Xcode, make sure you add them as folder references.

They will then be added as folders to the .app bundle:
