We have an iOS Point of Sale application where we want to show information on a customer facing iPad what is being inputted in the main iPad.
So basically we are looking to push information from one iPad to another iPad. I have seen some information about Bonjour network. Just looking for direction how to use it?
One of the things, I was thinking if we should send a push notification to 2nd iPad every time product is entered and call an web service to show the data.. It seems too much.
Thanks,

My scenario that I need to show the first Local Notification using Swift and then using the same identifier add another Local Notification, but without showing it as a popup in iOS device. So basically the flow would be like this:
Starting upload... <-- Show on the screen and adds to the Tray bar
Uploading photos... <-- Does not shows on the screen, but clears all the notifications and add another one in Tray bar silently (or changes previous one)
Uploading data... <-- Same as Uploading photos...
Finished uploading... <-- Same as Uploading photos...
Tried different ways, on Android it is not hard to do that, but iOS makes everything hard to do, is it even possible? :)
Thanks!
The reason it works on Android is because the "state showing" notifications are very Android thing. iOS is not designed for this kind of stuff because you almost never do something in the background of an app that also needs to be reflected to the user while user is outside of an app. So the real answer to your question is no. In iOS environment it is not possible to simulate Android way of showing status changes in a notification.
I am working on the app that shows Ads (Video or image) when iPhone is running. If I open any app(eg. Twitter) then also my Ads should be visible at particular interval of time. Is it possible to do so?
No. Your app will not be informed about any other apps being launched. Even if it were, you can't "force-grab" the foreground to display videos. That would totally violate any user interface principle established by iOS.
Besides the technical aspect I'd have my doubts of such an app surviving app review in general, though I don't know the specific part of the TOS right now.
It is possible to show your ads inside your application in intervals or in any pattern you like. However it is not possible to bring your app to foreground when in background to play ads, it is actually not recommended at all. Best thing you can do is set a timer when the app gets in background to send a notification.
I am creating a conference app for iOS 9, which makes a call. Once call is made it takes user to native iPhone screen. Later user can come back to our app to do various tasks, when call is running in background. We need to give a user option to control that iPhone speakers On/Off from our app itself.
But unfortunately, we are not able to find any document or sample on ths.
Kindly advice us how to achieve ths functionality.
I have developed an iOS enterprise app for iPad. When it is launched it connects to a webservice, gets some data, and stores it in Core Data. Then the next screens use this data and do what is needed, like fill UITextFields, drop downs, show the user a UIAlertView, etc. Basically i use the data, manipulate it, and save it.
Consider this: I install the app now in morning, I use it immediately, and then I click the home button on iPad and leave it there for couple of hours. I then launch the app, and it shows a black screen before crashing and going back to iPad main menu.
Why is it crashing like that? Any ideas?
If you need more information please let me know.
You need to check your logs for errors.
Plug your device to your computer and open Xcode/Organizer/Devices/Device Logs
Would anyone know the whereabouts of the documentation on how to implement AirPlay dual-screen functionality into an app?
e.g. http://www.apple.com/uk/appletv/airplay/
This link has very brief, but from what I can see totally sufficient information if you scroll down to "Make the Most of a Second Display".
In short, you register for notifications on a connect to an external display to get a handle to it, and switch between drawing on the two displays by using setScreen(). Besides that, everything drawing related should be "the usual".
Overview
The user can connect additional screens to an iOS device at any time using AirPlay or a physical cable. Each additional screen represents new space on which to display your app’s content, and is managed by a UIScreen object. For example, a game might show its content on a connected display and show game controls on the iPhone screen, as illustrated in Figure 1. Displaying Content on a Connected Screen
