iOS: preview excel and word files - ios

I have an app that stores data and files in CoreData. Some files are photos, and I can display them, some are excel and word files. What is the best way to view them? Should I save em on filesystem and open with url? Does there is some controller in UIKit to display them?

Did you tried to use QLPreviewController before
Check out this url for details
QLPreviewController
It's responsible for opening PDF, .XCL, .word files.
Or for a quick viewer you can load the files in UIWebView

How to highlight text in pdf using PdfKit

I am creating app where i need to load the pdf file from document directory and need to highlight text manually by user.
Also we need to export the updated pdf file and upload it to the server.
Is there any way to manage the same using pdfkit ?
Please share the sample code if available.
We are using the library as a reference is listed below

wicked_pdf create hyperlinks to local files

I wan't to create a PDF document, which contains hyperlinks to local files. E.g. when the PDF is downloaded, along with some files, the PDF contains hyperlinks to these files. Is this possible to achieve, and if so, how?
You could try the following. This method works in general for linking local files to HTML documents.
Link 1
Link 2
Notice the file:/// (3 slashes) before the location.

How to make a Photoshop (.psd) file have hyperlinks when saved as a .PDF file?

I created a template for a document i want to use, in photoshop.
I want to share this document as a PDF file.
I want some of the text i made in photoshop to work as hyperlinks and direct ppl to websites.
How do i save a photoshop file as a PDF and get hyperlinks to work in the PDF file?
I have tried using the slice tool. It works to assign a url and target.
But when saved as a PDF the links do not work.
Anyone?
I know that indesign allows for saving pdf documents in either print or web format. the latter allows for hyperlinks to be available. if photoshop does not offer this you can always add them in acrobat (not reader) and then resave the .pdf.

How to read pdf file in ios .I am not using UIWebView

I want to read a pdf file which is coming in URl from server. I am not using UIWebview.
So, i just want to know that is there any way to view that pdf file without downloading in to device. Just it be readable or buffered, not stored.
Any suggestions for that.
The easiest way to show a PDF outside of a UIWebView is using the QuickLook framework:
http://developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/UsingtheQuickLookFramework.html
However, as isn't unreasonable, Quicklook requires URLs of a "file" type.
So without using a UIWebView, you'll need to add your own code to download/cache/display, which isn't hard. If you need sample code, let me know.

iOS - Download files to application folder

I do have a UIWebview inside one of my UIViewControllers. The destination URL to be displayed within the WebView is a page on my server (therefore I have access to make changes on it).
That page basically has a list of PDFs to be downloaded (imagine an un-ordered list of hyperlinks each pointing to a PDF file).
I need a way to tell my App that whenever a file is downloaded from that WebView by clicking on one of the links, I need it to be saved inside my application folder instead of the iPhone/iPad memory.
Is there any way I can achieve that? Are there alternatives?
You can allow UIWebView to call your Objective-C delegate function. This link provides an overview of how to do it: http://dblog.com.au/iphone-development/iphone-sdk-tip-firing-custom-events-when-a-link-is-clicked-in-a-uiwebview/ Basically, the delegate function will be called on all requests from the UIWebView. You can examine if they are for links to a pdf files, and if so, write your own objective-c code to download the file and store it in your Application directory. You'll probably want to add some UI to let the user know what is happening. Otherwise you let the request go on as normal and it will be displayed in the web browser.
