Very simple countdown

[gadsadasd]

Hi, I want to create a simple countdown two
minutes. Every second that every time you change the number issued
a sound. A very simple thing: A UIButton and UILAbel.
Thanks thanks

Use the button's pressed event to start an NSTimer that triggers a method every second for two minutes. In that method update your label and play your sound.

NSTimer *timer;
int seconds;

-(IBAction)buttonPressed:(id)sender
{
    timer = [NSTimer timerWithTimeInterval:1.0
    target:self
    selector:@selector(Update:)
    userInfo:nil
    repeats:YES];
}

-(void)Update
{
   // update your label
   // play your sound
   
   seconds++;
   
   if (seconds > 120)
   {
      [timer invalidate];
      timer = nil;
   }
}

Something like that would probably work. May be some errors...

unfortunately does not work or might not get it to work.
The operation that I want is simply the fact
and a countdown showing the time UILabel. And then
every second for a sound.
Thanks

You'll need to explain what you're asking better...

I do not know how to explain. Here is a picture:

That's what I thought. It would be done the way I showed in my first post. That should be enough to get you started, no one here is going to write all of the code for you.
