iOS本地文件访问和webkit(iOS local file access and webkit)

iOS本地文件访问和webkit(iOS local file access and webkit)

我是iOS App开发的新手（我还没有真正开始，还处于设计阶段）。 我必须用我的应用程序完成的任务是从某个地方下载一个zip，将任何内容解压缩到本地存储并在嵌入的webkit小部件中显示其内容（带有javascript的html页面）。

问题是： 1）我的应用程序可以访问我的iPad存储内存的任何文件夹吗？ 2）我的应用程序的嵌入式Webkit小部件是否能够显示本地html页面（如file：///somewhere/over/the/rainbow.html？ 3）本地页面是否能够使用Ajax方法（通过httpxmlrequest）动态加载外部脚本或xml（也是本地存储的 - 即./something.xml）？

提前感谢您的帮助！

I'm absolutely new to iOS App development (I haven't actually started yet, still in a design phase). The task that I have to accomplish with my app is to download a zip from somewhere, extract anywere to local storage and display its content (html pages with javascript) in a embed webkit widget.

The questions are: 1) Will my app have access to any folder of my iPad storage memory? 2) Will my app's embedded Webkit widget be able to display local html pages (like file:///somewhere/over/the/rainbow.html ? 3) WIll that local page be able to use Ajax method (over httpxmlrequest) to dynamically load external scripts or xml (also locally stored - ie ./something.xml)?

Thank in advance for any help!

不，它无法访问任何文件。 应用程序在iOS上进行沙盒处理。 您只能访问应用包的内容和文档文件夹（应用程序独有的可写区域）。 是 - 如果所述内容属于（1）中提到的区域。 这就是基于Phonegap的应用程序的工作方式。 是的他们可以。 我们已经在我们的几个应用程序中广泛地完成了这项工作。 No it can't access any file. Apps are sandboxed on iOS. You can only access the app bundle's content and documents folder (a writable area unique to your app). Yes - provided said content is in the areas mentioned in (1). This is how Phonegap-based apps work. Yes - they can. We've done exactly this extensively in several of our apps.
