How to call function in every "X" minute?

Question

Hi folks,

I was trying to make a sample iphone application to update current location. I have a function that logs the current location, "logCurrentLocation", but I have no idea how to call this function automatically in every X minutes( or seconds).

Please advise me which method I need to look at in the apple documentation.

Thank you for your help.

Hi sungl,

Check out the documentation for NSTimer. It allows you to schedule a timer which will call a function (defined by a "Target" object and a "Selector" you want to call). You can change the interval at which the timer fires, and it should do the trick!

Answer 2

You need to set an NSTimer, have a look at this sample app

The timer in this sample app is 1 sec and calls a method that updates the display. Just implement a simmilar timer of duration x minutes and call which ever method you like :)
