No highlight effect on tapping uibutton

I created UIButton programmatically, it appearance is ok, but when i tap button there is no "highlight" effect, when u usually tap button. How to add this?

_payBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [_payBtn setTitle:@"    Оплатить    " forState:UIControlStateNormal];
    [_payBtn setTitleColor:[UIColor lightGreen] forState:UIControlStateNormal];
    [_payBtn setContentMode:UIViewContentModeCenter];
    _payBtn.tintColor = [UIColor lightGreen];
    [[_payBtn layer] setBorderWidth:1.0f];
    [[_payBtn layer] setBorderColor:[UIColor lightGreen].CGColor];
    [_payBtn addTarget:self action:@selector(didTapPayBtn) forControlEvents:UIControlEventTouchUpInside];
    [self.payContainerView addSubview:_payBtn];

You can use default methods to highlight a button:

 [self.button showsTouchWhenHighlighted];

If you want some kind of touch effect like setting background color from highlighted to normal you can use CABasicAnimation class with key backgroundColor for for background appearance:

- (IBAction) didTapPayBtn:(UIButton *)sender{

   CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"backgroundColor"];
   animation.fromValue = (id)[[UIColor lightGrayColor] CGColor];
   //    animation.toValue = (id)[[UIColor lightGrayColor] CGColor];   // optional
   animation.duration = 1.0f;  // animation duration
   //    animation.autoreverses = YES;   // optional
   //    animation.repeatCount = NSIntegerMax;   // optional    
   [self.button.layer addAnimation:animation forKey:@"ColorPulse"];
}

If you need to show the effect over button's shadow you can do like by changing the key value:

// inside viewDidLoad
self.button.layer.shadowOpacity = 1.0f;'

// inside didTapPayBtn action
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"shadowColor"];
[self.button.layer addAnimation:animation forKey:@"shadow"];
