How can I make a counter?

Question

How can I make a counter from 0 to 10 choosing the delay?

Answer 1

you need to use NSTimer,

Check the below code as reference.

- (void) startCounter {
     counterCount = 0;
    [NSTimer scheduledTimerWithInterval:0.09f target:self selector:@selector(showElapsedTime:) userInfo:nil repeats:YES];
}

showElapsedTime will be called after delay, you provide.

-(void) showElapsedTime: (NSTimer *) timer {
    counterCount++;
    if(counterCount == 10)
    {
      [timer invalidate];
    }

// Write your code here 
}
