i saw one application in App store.(files lite by olive toast). inwhich they have used
web server(webDAV url) to transfer file from PC to ipod or iphone and also another option bonjour.how can i use bonjour (what is it ?)..how can i do for my application?
internally how they have done?any help please?
Bonjour is Apple's "Zero-configuration networking". Essentially it allows you to advertise a service on the network by name, allowing other machines on the local network to discover it. There's plenty of high quality documentation available from Apple. Just google it.
Bonjour is just a way for your desktop application to discover the ip address of the iPhone. To actually transfer data to or from your device, you need to write that code yourself. Unfortunately Apple doesn't provide a framework to do this.
Some people use WebDAV, implemented with an open source framework.
Another option is to use ZSync, if you are using Core Data:

I am trying to prototype a solution to a problem and am currently exploring multiple routes I could try. Is it possible for one iOS device, running a certain app, to communicate directly with another iOS device, running the same application - without the need to be on the same LAN?
Solutions I am currently investigating are using Bluetooth and ad-hoc wireless connections.
Ideally, the application when installed would ask the user for the required permissions, and then would accept and/or send data to/from another client after a handshake had happened.
My concern with Bluetooth is that 'pairing' would need to happen with every device, rather than happen in the background once the user has installed the app. I have a feeling what I am talking about isn't possible from what I've been reading elsewhere on Stackoverflow.
Take a look at Bluetooth Low Energy.

Here is another example,
https://github.com/KhaosT/CBPeripheralManager-Demo
You might also want to look into GameKit and peer-to-peer connectivity there.
I can't tell you anything about it, but you might try looking at iOS 7. If that's an option, I'd take a look. Can't talk about what it is because of NDA though.
Depending on what you need to communicate, you could try checking out this project, which lets you share arrays of strings between iOS devices over Bluetooth LE.
You don't need to "pair" the devices and it can still communicate while the app is in the background. SimpleShare
Hope it helps!
From the documentation of MultipeerGroupChat:
MultipeerGroupChat sample application utilizes the Multipeer Connectivity framework to enable nearby users to discover, connected, and send data between each other. This sample simulates a simple chat interface where up to 8 devices can connect with each other and send text messages or images to each other. Here you will learn how to bring up framework UI for discovery and connections and also how to monitor session state, listen for incoming data and resources, and send data and resources.
This is an excellent example at developer.apple.com here is the link
https://developer.apple.com/library/ios/samplecode/MultipeerGroupChat/Introduction/Intro.html
Also this tutorial from Ralf Ebert demonstrates how to use Multipeer Connectivity framework for peer communication should help you.

I am looking for a way to have one iPhone app send a message to another app on a different phone (sort of like a Sender-Receiver set up). I am looking for the best possible way to do this. Does anyone have any ideas and/or tutorials?
Thanks for the help.
You should use GameKit. It is super easy to send messages between two iOS devices using it. Here's a great tutorial: Game Kit. You can also get more information about it here from the docs: About Game Kit.
You communicate by creating an ad-hoc bluetooth or local wireless network.
lmirak provided insightful info about device communication(especially about GameKit). I would like to add one more solution. You can use WiFi network to do your device communication.
See the link or download the sample application from developer.apple
The sample application named as WiTap. It demonstrates how to achieve network communication between applications. Using Bonjour, the application both advertises itself on the local network and displays a list of other instances of this application on the network.
If your app is only going to run on iOS, then you should use the fantastic MultipeerConnectivity library. https://developer.apple.com/documentation/multipeerconnectivity
If you need a solution that will work cross-platform, then one way to accomplish this is using sockets and connecting over a local network. On iOS you can use CocoaAsyncPods for sockets and NetService for discovery.
Here is a basic example app that does this: https://github.com/brendaninnis/LocalNetworkingApp
, which I explain in great detail here: http://brendaninnis.ca/connect-nearby-devices-part-1.html
I have written a VST/AU/RTAS synthesiser plugin for OSX and Windows that also has an iPhone equivalent. I would like to allow the two to communicate with each other over a local area network so that the iPhone app can be used to send MIDI controller data to the plugin. I plan to create a MIDI source on the iPhone and publish it as a Bonjour service so that the plugin running on OSX or Windows can find it and receive midi from it.
I have a couple of questions to ask about this:
1) Do I actually have to publish the MIDI source as a Bonjour service or does a coremidi host (running on iPhone) automatically publish itself?
2) Are there any code examples available that show how to do this sort of thing?
I have seen the following post but the answer to this only covers the client side, finding a Bonjour service but not the publishing side, and it transmits MIDI via OSC, and it only covers OSX but not Windows (I know, I'm not asking much! ;) )
How to send MIDI or OSC signals to a Mac application from my iOS application?
Cheers,
John.
AFAIK you'll have to publish the service yourself. NSNetService and NSNetServiceBrowser are the classes you need. Check out the companion guide. I found this article on Cocoa for Scientists particularly helpful in getting started. Both have some decent code samples. The Bonjour Browser is useful for testing.
The list of bonjour service types already has
apple-midi
and
imidi
But I think it's best to make up your own application-specific type name unless your app is plug-compatible with one of these services.
I'm trying to write a simple chat application for the iPhone (as an experiment). Is there a simple way for two devices to discover each others' IP addresses, and given the addresses is there a simple API or protocol that would let me send text messages back and forth?
I've investigated SIP (specifically Sofia and eXosip), but these tools exist as C libraries and are beyond my current ability to port them to the iPhone.
Update: I'm trying to connect two devices over the Internet (i.e. not over Bluetooth or a local wireless network, which is what GameKit does).
You're going to need a server that provides the match making service. Game Center makes this pretty easy, but your users will have to have Game Center accounts.
Alternatively, you can set up an XMPP (formerly Jabber, it's what powers Google Chat) server (I've never done this, but there are several available) and use the XMPP Framework for Cocoa. There are instructions for using it in iPhone apps here.
I'm sure there are other chat servers and client source also available. IRC and Mobile Colloquy come to mind.
Finally, you could write your own server using your favorite server language / framework. This isn't too hard (I've done it myself), but it's far from what I'd call simple, and I wouldn't use it for a production system.
There is support for exactly this kind of ad-hoc peer-to-peer networking in GameKit. Have a look at the second half of the GameKit documentation for details:
http://developer.apple.com/library/ios/#documentation/...
NSNetService is a good option.
Take a look at WebRTC Datachannels. WebRTC is a newer option with native iOS support a standard that is still being finalized, but it is more flexible should the iOS app need to communicate with browser or even android peers
I have developed an iPhone app which stores photos in the /Documents directory of my app.
I would like to add a feature which gives to the user the opportunity to transfer those pictures to his/her PC or Mac.
I don't really know how to do that.
What is the best way, using Bonjour, bluetooth, or directly USB (if it is possible) ?
I really need some advices on that point ...
Any ideas ?
PS: Forgive my English, I am French :-)
Try NSNetService to register the service in Bonjour, and NSFileHandle to send data over a socket connection associated with the service.
If you do not want to write a Mac or PC part for your app then you can also consider to build in a little http server that people can use to access the data in your app. There are some nice open source http servers available for Cocoa which you can find with Google.
Using Bonjour you can advertise your http server so that people can easily find it with a Bonjour enabled browser like Safari. (Your iPhone app's web server will appear automatically under the dynamic bonjour bookmarks items)
You've edited the question to say that it's about transferring photos. Could you store the photos on the iPhone's photo roll with UIImageWriteToSavedPhotosAlbum(), and let Apple handle getting them onto the computer?
Bonjour!
I mean that both as a greeting and an answer. You have to setup a bonjour connection over wifi to transfer files directly to and from an app. That's actually pretty simple to do on both the iPhone and Mac side. The PC is a little tougher.
You can do bluetooth but bluetooth capability is still fairly rare on desktops.
Without knowing more about your specific application, I agree with Graham Lee--either directly saving to the Camera Roll or giving the user an option to save one or more photos to the Camera Roll is much simpler than http/bonjour.
