Im implementing a reminder app.There are two reminders (one for everyday and other for future dates.)everyday reminder is working fine.In the app there are some tips and when user like one tip,i want it to be able to save that tip for some date in future(eg:august 29 9.00pm).can anyone help me what is the correct path for implementing this scenario.All the tips are saved in an array.How can i save the different time and dates user selected from date picker into an array and fire the local notification at correct time and displaying the tip user saved for that day.
(i tried using NSUserdefaults for saving the day and time and also retrieving the index of tip from array and comparing both but not working).

The problem is that your App needs to be running at the time in the future that the user wants to be notified, while the iOS or the user can kill your App at any time, or power cycle their device.
One way to do this would be to have a background daemon that runs all the time, but that is not permitted by the iOS Developer Agreement.
On *NIX systems you can use cron. While the iOS is based on FreeBSD, a form of UNIX, either it does not have cron or it is not available to App developers. I’m not entirely certain of that, so I suggest Googling around to see whether there is a way to implement periodic tasks on the iOS. But I’m pretty sure there isn’t, or I would have heard of it by now.
However, you could use Push Notifications. That would require that you also write a web application to save your users’ notification dates in a database, that would then issue a push notification via Apple’s push notification server at the desired time.
From an end-user perspective this is just what you want, but it also means that your total app, including the web application and database, just got a whole lot more complicated compared to what it would take to implement it with cron or a daemon.
There are push notification hosting services though, that could take care of most of what you need for a very modest fee.
