Question

I have an app which displays an image when I say some word, and the word is from my dictionary which I had exclusively created for the app.

Now I want that image displayed on my friends iPad simultaneously, when it shows on my iPad. Is there any way for that?

Thanks and regards,

Christy

If both iPads are in the same local network, you can use cocoahttpserver to run a HTTP-Server on every device and announce the services via Bonjour. Once a new picture is available, that devices connects the server on the other devices and informs it, that new data is available. The second device than will connect the server running on the first device and download the picture.
the advantage of this approach: the protocols you are using are well-know and a lot of additionally tools are available.

But you can also have a similar, more downlevel appoach, where you design your own network protocol. In that case I’d use Asyncsocket
