iOS determine the number of touches

In my app i need to know if the user is touching with two fingers or only one. How can i do this?. I have this code that works, but i only get where is the touch. How can i determine how many fingers are touching the view?

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{
      NSLog(@"touch at %@", NSStringFromCGPoint([touch locationInView:touch.view]));
      return YES;
}

Need help please. Thanks in advance.

In your target's action selector, you'll have access to [gesture numberOfTouches].

UIGestureRecognizer *gesture = [[UIGestureRecognizer alloc] initWithTarget:self action:@selector(myResponder:)];

- (void)myResponder:(UIGestureRecognizer *)gesture {
  [gesture numberOfTouches];
}
