<view animation="{{animationData}}" style="background:red;height:100rpx;width:100rpx; bottom:10px;position: absolute;"></view>

Page({

    var animation = wx.createAnimation({
      duration: 500,
      timingFunction: ‘ease‘,
    })

    this.animation = animation

    // animation.scale(2, 2).rotate(45).step()

    this.setData({
      animationData: animation.export()
    })
    var n = 0;
   //连续动画需要添加定时器,所传参数每次+1就行
    setInterval(function () {
      // animation.translateY(-60).step()
      n=n+1;
      console.log(n);
      this.animation.rotate(180 * (n)).step()
      this.setData({
