问题
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.

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!
