You will be needing a server for this. Its a long process. Briefing you with the overall details

• You get the information when users are loggedIn.
• User will try to send the image to the server first.
• Get the screenshots images continuously from the user screen.follow this link
• convert the image to NSData.
• From server detect the other user(to whom screen is to be shared.) send the data to that user. And convert the NSData into UIImage and update the UI accordingly.

• Loop the process.

  // for taking screen shot

   UIGraphicsBeginImageContext(self.window.bounds.size);
      [self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
      UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
      UIGraphicsEndImageContext();
      NSData * data = UIImagePNGRepresentation(image);
      [data writeToFile:@"foo.png" atomically:YES];

you can do this exchange the image stream(Current screen image context / Captured current screen) for both device vice-versa. Means transfer current context of your screen to connected device and make this process like continues sending/receiving like live stream of data.

Screen sharing working you get idea from following links.

1) Desktop sharing
2) Remote access of device
