Pop a view animation similar to the presentation of UIAlertView

float pulsesteps[3] = { 0.2, 1/15., 1/7.5 };
- (void) pulse 
{
	self.transform = CGAffineTransformMakeScale(0.6, 0.6);
	[UIView beginAnimations:nil context:nil];
	[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
	[UIView setAnimationDuration:pulsesteps[0]];
	[UIView setAnimationDelegate:self];
	[UIView setAnimationDidStopSelector:@selector(pulseGrowAnimationDidStop:finished:context:)];
	self.transform = CGAffineTransformMakeScale(1.1, 1.1);
	[UIView commitAnimations];
}

- (void)pulseGrowAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context 
{   
	[UIView beginAnimations:nil context:NULL];
