I'm interested in measuring the network traffic for my application. Ideally I would need to separate wireless from 3G network traffic. I can't seem to find any API that gets this information; however I see that there is at least one app in the AppStore that does something close (they actually sum up the traffic for the entire phone).
Any ideas?
I've found one approximate solution: getifaddrs can be used to get statistics on network usage.
One advantage is that it can get separate statistics for Wi-Fi and WWAN interfaces.
A disadvantage is that on multi-tasking devices those interfaces may be used by multiple applications and the statistics are cumulated.
I also was looking for solution and found it here:

I'm working on adding sharing support to my iPhone app. Right now, I'm using Bonjour to create plain TCP connections over a wifi network. This works great, except that it turns out that many wifi networks in the real world (for example, those at Starbucks and other chains) forbid Bonjour publishing and discovery over their networks.
So that limits the usefulness of sharing, since one of the use cases we imagined was that people could bump into each other where wifi was available and seamlessly share data with each other.
Is Bluetooth a viable alternative for this? We're sending large amounts of data (PNG images) over the wire, so latency and throughput might be one issue.
(I'm also interested in any other ways to make it easy to transfer data between two iPhone apps)
i want to measure network traffic of
GPS , 3G and WiFi separately
Application vise separately
in iphone , can any one suggest me the APIs to perform all above task or show me some example or road map.
There's no way to get those figures from the publicly documented APIs (and I don't quite know what you mean by 'network traffic of GPS', because GPS isn't a network protocol). So the answer to your question is: no, nobody can suggest it, because it's not possible within the public APIs.
You can probably do it using undocumented classes or on jailbroken devices, but if you're looking to put your app on the app store there's no point considering that because it will just get rejected.
I want to check the network requests an app is making from my iPhone. It's on the same WiFi network as my computer (or if it makes things easier, I can set it up to use an ad-hoc network). I don't want to see every packet, just the URLs which my iPhone is requesting. I don't care about the returned data all that much.
A simple solution would be much appreciated.
If you want to intercept the phone itself you'll need to point it at an http proxy you set up on a computer and watch the requests come through. Something like http://www.charlesproxy.com/ or there are most likely many free proxies.
Connect your computer to the rest
of your local network via Ethernet.
Turn on Internet Sharing from the
Sharing System Preference to share
your Ethernet connection via
AirPort.
Set your iPhone to
connect to the computer as its base
station.
Use Wireshark to
capture and analyze the packets.
I found a really nice repo on github named Wormholy https://github.com/pmusolino/Wormholy it will show every network request on your iphone, you only add it to your pod file and then on your app, you shake your phone and you will see all requests.
Easy to install
Transparent on your app usage
Overview and details of your request

I want to send some Text plus a image from one iphone application to other iphone app but restriction is I should not use a web server in between communication,Is there any way to fulfill it ?
Details: There are two independent devices and could be far enough say out of network. My requirement one app adds some text with a image and sends it to another iphone which can be at any long distance , and the app installed in another iphone will read that info and image into itself.
Actually there is a solution that meets your needs — and that fits to bbums answer:
Create a HTTP-Server on the iPhone, using cocoahttpserver. than you will ask some webservice like whatismyip.com for your public ip. with this your iPhone can be connected worldwide.
But very likely ur wifi-network is not forwarding your port to the iPhone. Ash.
And even if: Now it gets difficult. How to publish your ip from one phone to the other? hmmm... — I got it: I will exchange the information in a centralized space! In the web!
... wait — that would be a Webserver.
You see: Without any kind of server in the Web the users would need to exchange ip manually and have full admin power and knowledge about the local network.
So IMHO bbums answer is the only way to go.
PS: I am working with http server running on iPhones. In local network that works great, especially with bonjour. And you can use them over distance network — but only with reconfiguration of your router — something you shouldn't force your user to do
There is far from enough information to provide a specific answer.
two apps on two different devices?
are the two devices on the same network?
are the two devices both on WiFi?
do you need the user to receive a notification or something if the app isn't running?
If on same device, you can define a custom URL handler in the destination app and then openURL: in the source app to pass the data over. Encode your image and text into the URL, but be careful of size limitations.
If on different devices, there are many possible solutions, but answering the above questions will be critical to actually knowing what solution is appropriate.
Given your comment -- two apps, different devices, arbitrary networks -- then you are going to have to have some kind of server in between. Note that the recently added Game Center does have the ability to rendezvous two users, but it has a very particular user experience that may not be appropriate to your needs.
I would suggest that you investigate using push notifications to notify the receiving user of the availability of content. As for moving the content between, no direct connection is possible and you will have to have some kind of store-and-forward server in between. And, yes, a web server is going to be the easiest possible solution simply because HTTP is ubiquitous these days.
If there's no network of any kind available, but both parties have amateur radio licenses, then hooking the two devices up to HF packet radios might work.
THIS is super EASY.
I would code up some software that can turn data into modem signal, like the good old dial up modem. The device would actually make those annoying buzzing sounds.
You get the phone number for your friends nearest landline and call him.
He places his iPhone near the phones receiver in listen mode and you connect to his phone using your audible modem.
Bingo, via the power of sounds you have sent data which is decoded on his device and all for the very cheap price of a phone call, there are pretty cheap these days especially if you use Skype.
Easy Way (relatively speaking)
A way two apps on different networks can communicate without setting up a web server of some sort is as follows.
Use an existing third party storage system like DropBox.
Each app would need the login and password for your DropBox. Then both apps can read and write files that the other app can see.
An existing app that does this is a shopping list app called ShopShop.
The app on my phone and my wife's phone both link to the same DropBox account and the app keeps the shopping list synced up when one of us adds something to the list.
I was wondering what amount of time is required to convey information regarding the tilt and position (not gps) of one particular iphone to another. Could 2 iphones send and receive this information simultaneously? What about 3 iphones? I'm interested in an application that is able to simultaneously send and receive and make conditional decisions based on this information received all within a half a second-ish.
Any shot this is possible? If so, is bluetooth or wifi better?
Thanks a ton,
Jake
This is currently not possible without an intermediate server. (Without a jailbreak, which would make it possible, but extremely difficult)
I'm assuming your purpose is gaming, in which case, the latency associated with a trip to a server and back over a cellular data network, is likely to take too long for any satisfactory gaming experience. I don't believe it would be within half a second.
This will be possible via Bluetooth in the upcoming 3.0 iPhone software, but that is still under NDA, so you are not likely to be able to get any reliable performance numbers until it is released. If I were guessing, I would certainly guess that the latency associated with a direct Bluetooth connection would be FAR under half a second.
All you've got as an option right now is Wi-Fi or the Cell Network. If you use Bonjour over Wi-Fi, you'd have latencies in the milliseconds, but all the phones would have to be connected to the same access point. Take a look at the WiTap example.
It is definitely possible, you'd want to connect your peers over WiFi for best performance and reliability, but Bluetooth would be ok as long as your data packets were constrained to small sizes (< 1k). Check out this documentation and sample code to see how to access UIAccelerometer:

The trick is that the update frequency is controlled in part by the systems needs, so there may be a window (while the system is attempting to update device orientation) wherein your application receives no updates.
