我正在使用关键帧动画旋转圆。在android浏览器,chrome和Mozilla中运行正常。但是在iPhone的Safari / Chrome浏览器中,单击按钮时的动画速度不会改变。
class App extends React.Component{
state = {
speedClass : "two"
};
render(){
return(
<div>
<div className={"spinMe " + this.state.speedClass}>I am spinning</div>
<button onClick={this.handleClick}>Change speed</button>
</div>
);
}
handleClick=()=>{
this.setState({ speedClass: this.state.speedClass === "two"?"one":"two" });
}
}
ReactDOM.render(
<App/>,
document.getElementById("root")
);
.spinMe{
width:100px;
height:100px;
border-radius:50%;
border:1px solid red;
display:flex;
justify-content:center;
align-items:center;
}
.spinMe.one {
-moz-animation: spin 1s infinite linear;
-webkit-animation: spin 1s infinite linear;
-o-animation: spin 1s infinite linear;
animation: spin 1s infinite linear;
}
.spinMe.two {
-moz-animation: spin 2s infinite linear;
-webkit-animation: spin 2s infinite linear;
-o-animation: spin 2s infinite linear;
animation: spin 2s infinite linear;
}
}

我找不到任何解决方案,请帮助我解决此问题。在iPhone中,速度不起作用。可能是什么问题?
答案 0 :(得分:0)
为解决此问题,我两次添加了相同的关键帧动画。在单击时,我切换了动画,它才起作用!
