How do I prevent the iPhone screen from dimming or turning off while my application is running?

I'm working on an app that requires no user input, but I don't want the iPhone to enter the power saving mode.
Is it possible to disable power saving from an app?

In swift you can use this as
UIApplication.sharedApplication().idleTimerDisabled = true

Swift 3:

Solution 4 - Ios
I have put this line of code in my view controller yet we still get customers saying the screen will dim or turn off until someone touches the screen. I have seen other posts where not only do you programatically set
UIApplication.sharedApplication().idleTimerDisabled = true
to true but you must reset it to false first
UIApplication.sharedApplication().idleTimerDisabled = false
UIApplication.sharedApplication().idleTimerDisabled = true
Sadly this still did not work and customers are still getting dimmed screens. We have Apple Configurator profile preventing the device from going to sleep, and still some devices screen go dim and the customer needs to press the home button to wake the screen. I now put this code into a timer that fires every 2.5 hours to reset the idle timer, hopefully this will work.

We were having the same issue. Turned out to be a rogue process on our MDM server that was deleted in our account but on the server was still sending the command to dim our devices.
