Question

Using NSTimer for my application in which I have to show countdown timer with initial timing equal to 100sec. It shows 99,then 98..96..94..92…86 and so on. But I want each sec to show up. Here is my code….

   -(void)updateTimerLabel{
   if (timeRemaining>0 ) {



    timeRemaining=timeRemaining-1.0;
    timerLabel.text=[NSString stringWithFormat:@"%.0f", timeRemaining];


    countdownTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateTimerLabel) userInfo:nil repeats:YES];
    }
}

Answer 1

Try following code

int i =100;

-(void)viewDidLoad
{
[super viewDidLoad];
[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(theActionMethod) userInfo:nil repeats:YES];  

}

-(void)theActionMethod
{
   if(i > 0)
   {
      NSString *str = [NSString stringWithFormat:@"%d",i];
      lbl.text = str;
   }
   i--;
}
