objective c - Basic iphone timer example -

OK, I've searched online and even seen in some books for answers because I'm apple For the NSTimer I am trying to implement 2 timers on the same scene that each has 3 buttons (START - STOP - reset)

The first timer is 2 minutes and then the beep Is counted from.

The second timer is counted from 00:00 indefinitely.

I'm assuming that all codes will be written in 3 ways behind the different buttons, but I have been completely lost trying to read apple documents. Any help would be greatly appreciated.

Actually what you want is an event that sets fire to every second, or Probably at intervals of 1/10th, and while the timer is ticking, you will update your UI.

The following will create the timer, and add it to its run loop. Save the timer somewhere so that it is necessary when you can kill it. [NSTimer *] createTimer {// Make timer run on the loop return [NSTimer scheduled timer with timer: 1.0 target: self selector: @silator (timerTacket :) user info: zero repeats Is: yes]; }

Now type a handler for the timer tick:

 - (zero) timerTacket: (NSTimer *) timer {// Command Timer 1 ... this is your Have UI, Tick and Redr [my satvoc tick don;]; [MyStopwatch.view SettingsDisplay]; // increase timer 2 ... time of collision in the UP and redraw ...} 

If the user hits a button, you can reset the count, or start or stop the ticking Are there. To end the timer, send an invalid message:

  - (zero) verbatim (id) sender {// stamp tires [myTimer invalid]; }  

Hope this helps you.
