Try this. You can make some changes so it suits your need,

        CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform"];
        anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
        anim.duration = 0.125;
        anim.repeatCount = 1;
        anim.autoreverses = YES;
        anim.removedOnCompletion = YES;
        anim.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)];
        [senderView.layer addAnimation:anim forKey:nil];

Hope this helps.
