I already go Inter application communication in iphone but is it possible to communicate two ios apps. or alteast i want notify second app when something happens(event) in First app
Read this for more information on inter-app communication. This requires though that the other developer of the app you want to communicate with, handles a URL Scheme and you know what it is. Or that the developer supports the "share"capability in iOS. If you develop the apps that communicate, you should either create your own URL scheme or use App-Groups. I hope this helps :)
