Can you help me with some solution if possible. I am now really in need of some solutions.
Thank you.

Alas, you can't do anything about PDF shown in a UIWebView.
You need to work hard parsing PDF files and manipulating it.

How can I prevent a PDF file from being downloaded or printed with PHP or JavaScript?

I am looking for ways to present a PDF file in the browser but make it not downloadable or printable.
If someone really goes through all the trouble to disable the JavaScript library or anything like that, that is fine. This is more for the reason that the content within the PDF will be updated regularly so if you download it it will be out of date by the next day.
I also cannot rely on marking the pdf as protected or encryption as a reasonable way to accomplish this.
If you have any library recommendations or anything else it would be appreciated. I am currently exploring if it is feasible using PDF.js and ViewerJS
I was able to find a solution using ViewerJS and this CSS. The CSS shows a blank page when you try to print (ViewerJS already distorts it to a non-printable state) and ViewerJS prevents you from downloading as a PDF file and instead tries to save as an HTML file.
This meets the requirements of making it just inconvenient enough to discourage users from trying to download the file since the file is always easily accessible on almost any page of the site.

Programmatically generate preview of Adobe files

I am willing to programmatically generate file previews for a large set of Adobe files. This should be done programmatically (not via user interface via recorded actions).
The idea is to generate jpg/png previews for psd files, pdf preview for indd files and so on.
Is there a library or SDK to easily do that?
I am open to every programming language that can get the job done, however I prefer a js solution since I am willing to run the script on a nodeJS server.
Is there any system requirement or program to be installed to make this thing work? Do I need an Adobe subscription to do that?
Thank you in advance.
I cannot find yet a proper solution in JavaScript. But this is a reference link I found on search engines.
https://unix.stackexchange.com/questions/11835/pdf-to-jpg-without-quality-loss-gscan2pdf
With ImageMagick on a server, it may help solve the problem.
Another reference link is on about to improve the speed and reduce the memory consumption. This may also help you integrate it on your server.

This code snippet may help you. You may have to apply back-ends on your server instead of directly integrating it in your NodeJS server.

Navigate PDF File using Jquery

I have a question about PDF files with Jquery.
Though most browsers has an embedded PDF Viewer, but what i need is something totally different.
while i was browsing IKEA Catalouge http://onlinecatalogue.ikea.com/TR/tr/IKEA_Catalogue/
i found it simple and professional, viewing the catalouge this way is so easy and nice, but on the other hand it's using Flash which I don't recommend !
So, is there any possible way to read the content of a PDF File using Jquery and then i will write the arrow keys function to go to the next page or go back and so on ?
Waiting your help and Ideas.

Ways to format one-liner JavaScript file

What are some of the best and quickest ways to format a JavaScript file.
I ask because I've downloaded a file called slides.min.jquery.js and I
would like to know how to change it so instead of being a one-liner it
is formatted properly.
I've got Aptana Studio but don't know how to open a JavaScript Project.
Any ideas? Thanks. Or else another tool will do.
Thanks.
You can use a tool like jsbeautifier to de-minify the compressed js.
Firefox has a plugin called deminifyer which can be used for this purpose as an offline solution.

How to migrate browser-based HTML5 and Javascript code into Xcode?

I have an HTML file containing JavaScript code, which is read by PC browsers(like IE).
Now I want to "migrate" those codes to make it part of my iOS app.
Is there an easy way to do this? I now using Titanium is a good way but what if I intend to use Xcode? (Also, the HTML contains some JQuery codes.)
Thank you very much!
Use UIWebView and you can run it as is.
