IOS9版本9.2（Iphone 6s）中的Greensock Lib TweenMax问题

Question

我遇到了一个问题，下面是我用来制作动画的代码。

var showStep1 = function() {
    beer1.style = "display: block; opacity: 0";
    beer2.style = "display: block; opacity: 0";
    TweenMax.to([beer1,beer2], 0.3, {autoAlpha: 1,scale:0.4});
    button.style = "display: block; opacity: 0";
    TweenMax.fromTo(button, 0.5 , {scale: 0, autoAlpha: 0}, {scale: 1, autoAlpha: 1});



};

var hideStep1 = function() {
    pyro.style= "display: block; opacity: 0";
    TweenMax.fromTo(pyro, 0.003, {autoAlpha: 0}, {autoAlpha: 1});
    TweenMax.to(beer1, 1 , {left: 110,rotation:13});
    TweenMax.to(beer2, 1 , {left: 235, onComplete: hideStep1Complete,rotation:-12},'-=1');


};

var hideStep1Complete = function() {
    beer1.style = "display: none;";
    beer2.style = "display: none";
    button.style = "display: none";
    bg.style = "display: none";
    pyro.style= "display: none";


};
    showStep1();          


var showStep2 = function() {
    bg2.style = "display: block; opacity: 0";
    TweenMax.fromTo(bg2,0.3,{autoAlpha: 0},{autoAlpha: 1,delay: 1.1});
};




document.getElementById("bg").addEventListener("click", function(){
    hideStep1();
    showStep2();  
});

它在包括Android和IOS（11，12）在内的所有设备上都运行良好。但是我看不到IOS9上的任何动画，确切地说是9.2版。

这就是我在HTML中放入的绿色袜子和tweenmax。

有人可以教我如何纠正它吗？拜托。

非常感谢所有人。
