Another blog post explains how to deal with this: How-to: Prevent iPhone from Deep Sleeping The code in the how-to isn't the one I'm currently using, though, but the demo project on GitHub is updated.

Any new developments on this? I am working on an app that has a stopwatch and I would like it to work when the screen is locked so that the user may hold the device however they choose without accidentally pressing the cancel button, but the timers are stalled as soon as the screen is manually locked.

To Shabbir : This code is not working on my side (OS3.1.2)

nice tip. I didn’t connect the two cause I have a timer firing in one program that didn’t have this problem after adding the code to disable the idle timer but in another it seemed idle timer didn’t make a difference (on 3.0 of course). Seems like having something (unecessarily) ticking away solves it (ugh).

I’m sorry, if I offended you with my annoying bad grammatical skills. (Am I really?!)

Why do you use so many unnecessary commas when you write? Only read the first two paragraphs and couldn’t take it anymore.

I think I found a better way to fix this, rather than firing a silent sound every 10 seconds. You can try this, I used this with my alarm application. For whichever NSTimer you need to work while the iPod/iPhone is sleeping add this line of code

[[NSRunLoop currentRunLoop] addTimer:exampleTimer forMode:NSRunLoopCommonModes];

The post is almost ready.

I ran into a little problem with the rendering of the code quotes. I fixed this, but the post is not quite ready to be published, yet.

I will upload the complete project I built to my github, too (including the needed silent sound file).

Tomorrow it will all be online, double promise!

Need to get some sleep now.
