iPhone sleep

[Michael]

I'm writing a task timer in HTML/CSS/Javascript and plan to use
phonegap. My timer plays an "bell" sound when a certain amount of
time working on the task has elapsed. However, if the iPhone goes to
sleep while the timer is running, the bell doesn't sound. Is there a
way in phonegap to either (i) stop iPhone going to sleep (I think the
answer to this one is "no") or (ii) programatically waking it from
sleep at a certain time? I presume these things are possible in a
native app written in Objective-C but I want to avoid Objective-C if I
can.

You could write a plugin to create an alarm event that will be
serviced by iOS.

[Giacomo Balli]

you can disable sleep.

Thanks everyone! That's plenty to keep me going for now. Switching
off sleep seems like the easier option - I might try both ideas out
and See how I get on. It's a relief to know it can be done... I was
worried I was going to have to scrap everything and start learning
Objective-C!

If you alarms are too far in to the future you may not have any
battery left to actually do the alert.

This is one of those Apple approval grey areas - you may have to alert
the user that the phone will be kept on and that long period alarms
will result in shorter battery life.
