There is far from enough information to provide a specific answer.

<ul>
<li>two apps on two different devices?</li>
<li>are the two devices on the same network?</li>
<li>are the two devices both on WiFi?</li>
<li>do you need the user to receive a notification or something if the app isn't running?</li>
</ul>

If on same device, you can define a custom URL handler in the destination app and then <code>openURL:</code> 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.

<hr/>

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.

<ol>
<li>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.</li>
<li>You get the phone number for your friends nearest landline and call him.</li>
<li>He places his iPhone near the phones receiver in listen mode and you connect to his phone using your audible modem.</li>
<li>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.</li>

blocks|key|3313012|text|实际上，有一种解决方案可以满足您的需要--并且适合于bbums的答案：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3313013|使用cocoahttpserver在iPhone上创建一个cocoahttpserver。而不是问一些像whatismyip.com这样的ask服务来获取您的公共ip。有了这个，您的iPhone就可以连接到全世界。|3313014|但是很可能您的wifi网络并没有将您的端口转发到iPhone。阿什。|3313015|即使:现在变得很困难。如何将你的ip从一部手机发布到另一部手机？嗯..。-我明白了:我将在一个集中的空间交换信息！在网上！|3313016|..。等等-那会是个网络服务器。|3313017|您可以看到:如果Web中没有任何类型的服务器，用户将需要手动交换ip，并且拥有完全的管理能力和对本地网络的了解。|3313018|所以IMHO的bbums答案是唯一的方法。|3313019|3313020|PS:我正在使用运行在iPhones上的http服务器。在本地网络中工作得很好，尤其是与bonjour。而且您可以通过远程网络使用它们--但只有在重新配置路由器时才能使用--这是您不应该强迫用户做的事情。|3313021|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/3824977/iphone-app-communication-without-using-webservices/3825220#3825220|1^0|Q|5|0|0|0|0|0|0|0|7|5|1|0|0|0^^$0|@$1|2|3|4|5|6|7|11|8|@]|9|@$A|12|B|13|1|14]]|C|$]]|$1|D|3|E|5|6|7|15|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|16|8|@]|9|@]|C|$]]|$1|H|3|I|5|6|7|17|8|@]|9|@]|C|$]]|$1|J|3|K|5|6|7|18|8|@]|9|@]|C|$]]|$1|L|3|M|5|6|7|19|8|@]|9|@]|C|$]]|$1|N|3|O|5|6|7|1A|8|@]|9|@$A|1B|B|1C|1|1D]]|C|$]]|$1|P|3|-4|5|6|7|1E|8|@]|9|@]|C|$]]|$1|Q|3|R|5|6|7|1F|8|@]|9|@]|C|$]]|$1|S|3|-4|5|6|7|1G|8|@]|9|@]|C|$]]]|T|$U|$5|V|W|X|C|$Y|Z]]|10|$5|V|W|X|C|$Y|Z]]]]

Actually there is a solution that meets your needs — and that fits to <a href="https://stackoverflow.com/questions/3824977/iphone-app-communication-without-using-webservices/3825220#3825220">bbums</a> 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 <a href="https://stackoverflow.com/questions/3824977/iphone-app-communication-without-using-webservices/3825220#3825220">bbums</a> 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

blocks|key|3313041|text|简单的方法(相对来说)两种不同网络上的应用程序可以在不设置某种web服务器的情况下进行通信的方法如下。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3313042|使用现有的第三方存储系统(如DropBox+)。每个应用程序都需要DropBox的登录和密码。然后两个应用程序都可以读取和写入其他应用程序可以看到的文件。|3313043|一个现有的应用程序就是一个名为ShopShop的购物清单应用程序。我手机上的应用程序和我妻子的手机都链接到同一个DropBox帐户，当我们中的一个在列表中添加一些内容时，应用程序会保持购物列表同步。|3313044|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

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 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.
