Editable Webview/TextView ? Or Any other Controller?

I am working on a project which can edit any document file whether it is doc, rtf, txt, pdf file.

After editing user can save or you can say update that file.

Please ad开发者_如何学JAVAvise .. how can anyone edit pdf or doc and re save it ?

There is no support for editing pdf or doc files in iOS4. If you want this you'll have to write it yourself.

A UIWebView can natively interpret a lot of document formats but there is no editing for this. If you just want to open these formats I would recommend a UIWebView. If you really need to save to a certain format, you'll have to look around for a framework that can save text to the formats you need. Or you're going to have to do it yourself.
