Keeping iOS from going to sleep

[Wild_Eep]

I'm writing an app that displays useful location-based information to the user continuously.

At the moment, after a certain interval, the iOS device goes to sleep.

I'd like the iOS device to remain awake while my app is running.

What is the best approach?

The only suggestion I've read so far is to play a sound every few minutes. Perhaps the sound file could contain silence. (As I write this, I'm thinking about the case where a user is playing music in the background. I wouldn't want to impact the music playback. I'll have to test this a bit.)

Are there any other approaches I should consider?

Hi Eep,

have a look at

iphoneLockIdleTimer
iphoneUnlockIdleTimer

in the iOS Release Notes (p. 40 in version 5.0.2).

Kind regards

I've been working on a similar app that records a GPS path at a user-specified interval. I've had settings/auto-lock set to never, which I assume has the same effect as iPhoneLockIdleTimer. The problem with this is that the battery drains rapidly. A 4S lost 25% of its charge in 1 hour of recording yesterday. Is there a way to dim the screen to conserve power while the app still runs?
