I have seen applications for iPad that let you view dxf and dwg files.
Does anyone know where to get info on how to do this? Are there any available tutorials? I haven't been able to find any.
I really need some direction on how to do this. The application I'm making just needs to show the files and layers.
Thanks for any help.
At present RealDwg is not available on iOS platform, so no way to view local dwg/dxf files.
But you have the other option. You create servers which open dwg files and send entities information in some format to your app, then your app can shows them. Through this way, your app can handle extremely large file. See AutoCAD WS.

I'm currently studying swift and came up with such a question:
What are best practices to work with custom user files like .pdf, .doc?
For instance, I have application, that loads different files from server like .pdf, .ppt, .zip and so on, how to present them inside my app?
While googling I came up with solutions mainly for images, but nothing particular for other file types.
For now, what I have is - downloading files from server using Alamofire and saving them to documents directory.
Could anyone please recommend how to present this files inside my app after I saved them?
Possible solution that comes to my mind is web view, but what about zip? Is there some kind of universal solution? I know that there is Files App in iOS 11, but what about iOS 10?
Many thanks for your attention!
I've been asked to add a file browser to an existing Objective C application that uses a WKWebView to load up a Javascript internal app.
Currently we have the capability of looking at the pictures on device to upload images into the app, but I've now been asked to do the same with more generic file types, specifically PDFs.
What I've read so far is that this is only possible if a file is stored in a specific part of the file system and only if the app knows exactly where the file is to begin with, but what I need is the capability to browse to a certain degree.
What I'd like to know is whether this is possible and if there is a good place to start on that?
Thanks.
I am making an iPad application (iOS 5.0/5.1 with ARC and storyboard) for which I need to download an image or sound file from my server and then use it as background for all the screens of my application. I was thinking of keeping a placeholder image/audio file bundled within my application which I will refer to within the storyboard. Then when I get the file from the server, I can replace that image with the one coming from the server. However, I'm not sure if this can be done based on the directories that the app has access to.
Pls let me know if you can direct me whether it's possible to go down this road? and if yes, then which directory should I be downloading the image files to?
Thanks in advance for your help
I understand the basic of Document Interaction Programming and UIDocumentInteractionController and I've got it working in my app. However I'm having trouble with specific details of using custom file types. I can't find this addressed in the Apple docs anywhere.
My app uses it's own file types with unique extensions. The files themselves are just plists (xml), but I want the device to treat the files as only openable in my app. Originally I implemented the Document Interaction stuff to treat them as XML while I got it working, but now I want it to treat them as binary files that it needs to hand off to my app.
At the moment, if you have one of my files in an email attachment, iOS first shows the QuickLook (which just spews all the text content of the xml out) before you can choose to Open In. Similarly if one of my files is opened with Safari, Safari just shows the XML and doesn't give you the option to show it in my app at all.
So how do I get iOS to not treat my files as XML? I've changed the "Conforms to UTI" value and "public.mime-type" value in the info.plist, but it seems to have no effect.
Any tips greatly appreciated.
As far as i understand the UIT concept of Apple you cannot just change the file extension to change a potential UIT of the file. If the file contains XML-Data, other apps as well as internal apps might recognize your content and show it internally as XML.
Try to store your Plists with NSPropertyListSerialization NSPropertyListBinaryFormat_v1_0 (then you readble XML)
When you did that without success, why not trying this:
use zlib to compress the XML plists afterwards to a zipped file.
make a "unique" file extensions (<file>.myappname)
this should "hide" other apps and quick view.
Tell me if one of the ways did work for you.
For a project we need to download and save pdf files on an IPAD device for offline use through an AIR for iOs application.
After a lot of searching I haven't found much information on this subject. My question is, can it be done, and if so, can you provide us with some pointers to lead us in the right direction.
Thanks for your time!
Sure, first you check if you can access the web - can use a class like air.net.URLMonitor, if you can you can set up a URLStream instance.
You get data while its downloading the file using the progress event, write that out to a File instance using the FileStream class.
To display the PDF file you can use a StageWebView or HTMLLoader.
