1、page入场动画可以在uni.navigateTo设置

uni.navigateTo({
	url: '../test/test',
	animationType: 'pop-in',
	animationDuration: 200
});
uni.navigateBack({
	delta: 1,
	animationType: 'pop-out',
	animationDuration: 200
});

<navigator animation-type="pop-in" animation-duration="300" url="../test/test">navigator</navigator>
<navigator animation-type="pop-out" animation-duration="300" open-type="navigateBack" >navigator</navigator>

"style": {
	"app-plus": {
		"animationType": "fade-in",
		"animationDuration": 300
	}
}

2、组件动画可以使用uni.createAnimation(OBJECT)实现

<view :animation="animationData" style="background:red;height:100rpx;width:100rpx"></view>

export default{
  data() {
    return {
      animationData: {}
    }
  },
  onShow: function(){
    var animation = uni.createAnimation({
      duration: 1000,
        timingFunction: 'ease',
    })

    this.animation = animation

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

    this.animationData = animation.export()

    setTimeout(function() {
      animation.translate(30).step()
      this.animationData = animation.export()
    }.bind(this), 1000)
  },
  methods:{
    rotateAndScale: function () {
      // 旋转同时放大
      this.animation.rotate(45).scale(2, 2).step()
      this.animationData = this.animation.export()
    },
    rotateThenScale: function () {
      // 先旋转后放大
      this.animation.rotate(45).step()
      this.animation.scale(2, 2).step()
      this.animationData = this.animation.export()
    },
    rotateAndScaleThenTranslate: function () {
      // 先旋转同时放大，然后平移
      this.animation.rotate(45).scale(2, 2).step()
      this.animation.translate(100, 100).step({ duration: 1000 })
      this.animationData = this.animation.export()
    }
  }
}
