UIView animationWithDuration not working second when called twice

I have created a category on UITextField which allows to animate between red and white color as shown below:

@implementation UITextField (Additions)

-(void) flash
{
    [UIView animateWithDuration:2.0 animations:^{

        [self setBackgroundColor:[UIColor redColor]];

    } completion:^(BOOL finished) {

        [self setBackgroundColor:[UIColor whiteColor]];
    }];

}

@end

I call it like this: 

[self.paymentTextField flash];

First time it works and it shows the red background and then switches back to white color. But on second call it does not do anything.

I'm not sure why that doesn't work. I tried it and got the same thing. However, since the color doesn't really animate, you can do it like this instead:

self.backgroundColor = [UIColor redColor];
[self performSelector:@selector(setBackgroundColor:) withObject:[UIColor whiteColor] afterDelay:2];

This should give you the same look.
