Sometimes I see (mostly iOS) apps, that serve their own HTTP content, which can be accessed with browser on local network in order to transfer files, for example certain audio or video players. In Android world, this is not so much an issue, since the user can access device filesystem using USB cable, but this is not possible on iOS.
Is there any tutorial/best practice/other resource providing deeper insight into this topic? I already did some research and tried to discover some tools for this purpose, but I did not find anything describing exactly this use-case.
Could somebody give me a hint, where to get started?

My client wants a mobile-app that can run with no WiFi and no cellular network available. I think that a PWA gives them the most cost-effective way to meet their needs, accept that the app needs to know location even when there is no network available. To do this the PWA would need access to the true-GPS, i.e., the info gathered by the GPS chip talking to the satellites. It's my understanding that a PWA does not yet have this access and there is no date for when we can expect it. Could we buy or develop a native mobile app that delivered the GPS-info to my PWA? I've seen some discussion of this using Cordova, but I would like to avoid diving into that world if I can.
I put my Android into airplane-mode and took it for a walk around the block. The PWA that I had installed on the Android was still able to give me the updated location. So perhaps the discussions and complaints I see on stackoverflow, etc., regarding this not working, are out-of-date. BTW: In the navigator.geolocation options I have:
enableHighAccuracy: true
so hopefully the browser uses this as a hint to use the GPS-chip if available, and not care if there is no network available.
I'm working on an app that connects to a security camera. The camera has its own SIP server (Asterisk).
I'm having a very hard time finding a reliable iOS library to connect to the camera.
Can anyone recommend a high-quality SIP library that will stream video? I've tried several so far and none of them are fit for the task (I don't want mention them by name).
Or is there another way to access the video (using webRTC or possibly AVFoundation via the Asterisk server)?
I do not have a lot of experience with hardware, so I'm a bit lost.
What are you looking for called MCU(media control unit). There are some free availible for vido, but all are early beta and very hard to setup.
Just from my own general curiosity, I was wanting to see if it was possible to stream LIVE audio between iOS devices by online using bluetooth or by "enslaving" one device over a local network—basically the same experience as a phone/Skype call. I have found tuts/information on how to stream a saved file and solutions that use a server side solution, but not exactly what I am looking for.
Anyone with solutions, information, or what not to get me started would be much appreciated.
Apologies in advance for the general-ness of the question.
I'm writing a multiple client iOS app for viewing the video feed from a single camera. Can the QX10 api support two (or 3) iPad's discovering/viewing the same QX10 at the same time?
I've been looking QX10 sample code, the camera api docs, StackOverflow, and of course the dev website and haven't seen an answer. I'd just buy the bloody thing to test with, but there are none nearby and I was hoping to avoid having to mail order/return it if it didn't work.
....And we're not locked into HW. If there's a better option, I'm open....
I don't believe it does. For ios, the camera creates a network that the ios connects to. (In ios settings/wireless) Any further attempts to connect to the camera from another device fail. Since the API only works after a network connection is established, I don't see how the API could possibly allow 2 devices could connect at once.
(No extraneous words in this post b/c that will get edited which auto down votes the question.....ahhh internet)
I did not try it, but you could use a computer with nat. For example an openrwt router to open up multiple wifi interfaces, one to connect to the camera, using the 10.0.0.0 network the camera uses and then an other network to connect your clients with NAT.
The question would be when the API would start to get confused.
So depending on what you want, maybe some mapper on that helper-computer could
do some proxying of information.
So in theory with an external box, maybe, but as Oldmicah said, it seems that only
one device can connect at the time (at least my QX100 also behaves like that). :(
I develop an enterprise application for iOS and the user should be able to add files from the desktop to the application.
I implemented this using filesharing, which works great.
Now this company wants to get rid of iTunes from their machines (which is quite understandable, iTunes is a very invasive process).
The question is, is it still possible to somehow use filesharing without iTunes? maybe with another application?
Or what other way is there to send files to the app (preferrably without the need of an internet connection)
//edit: must work on windows 7 and must not require to install iTunes (there are some other tools that allow access to the iPad filesystem, but they go through drivers installed by iTunes)
You could exchange data via the local wireless network (a connection to the internet is not required, just the iOS device and the Windows computer need to be on the same network).
One option:
You can then create a simple TCP/IP connection over sockets between an iOS app and a Windows application and exchange the data you want.
However you probably need to implement a suitable simple Windows application to do this.
An other, maybe simpler, solution:
You could start a webserver in your iOS-App and show it's IP on the screen. By entering this IP in a browser on the desktop computer you can access websites on the iOS device, which can make documents available for download or receive uploads.
For how to do this, have a look at this question.
There are a number of ways to achieve this, ranging from trivial to sophisticated.
Your question says that you would prefer to avoid an internet connection. Simple solutions may require it - if you want to abstract the difficult parts, you're going to have to let somebody do the dirty work, and that's probably going to be someone(thing) on the internet. Midrange solutions may require a network but not internet connection. A sophisticated solution could probably be whatever you want - but one thing I would say, is that trying to tap into the USB connector is either going to result in a hacktastic or very complicated solution to implement.
One method would be to integrate a third party framework that basically does what your looking for. Look at the Dropbox development kit, for example - allowing Windows (or any platform) users to drop files on their desktops into a shared dropbox, and this can then be read by an iOS application which includes the iOS drobox API.
Another method would be to setup a simple WebDAV server in your office. Host it on a windows box, or a cheap linux box. Give users desktop's access to the share via whatever protocol you want (eg, Windows File Sharing). Then you'd implement a WebDAV client in your app (eg, WTClient) to pull files.
Finally, you could build your own transmission system. A sophisticated example might involve Bonjour and TCP/IP, a simpler-but-custom solution may involve a simple JSON web service running off a local (or remote) server.
I have suggestion but that will require the Internet. I would suggest you to use the DropBox API in the windows and iPhone both. It's awesome to use and very simple for file sharing.
Now a days everybody have dropbox account and have files in it to share. So that shouldn't cost anything other than a bit of implementation (this learning can also be used in other file sharing applications).
Here are some guidance:
iOS
REST API
You can add apps and documents to USB-connected devices with the Apple Configurator
You may use a simple Ftp server installed on PC, so you can connect to server from Ios and upload/download files from iOS to PC....
http://developer.apple.com/library/ios/#documentation/Networking/Conceptual/CFNetwork/CFFTPTasks/CFFTPTasks.html
All work is done by Pc and your app will use IP (Intranet or Internet) of PC to share all files.
From Ios you can read all files in FTP server and work with them.
I use the FileBrowser app to get access to network shares over WiFi and will allow you to load supported files to the device. The company responsible is creating an API to allow you to do this within your own app: https://twitter.com/#!/Stratospherix/status/193114857271336960
