ios中scroll-view组件的bindscrolltoupper事件和bindscrolltolower事件 无法实现scroll-into-view功能（在没加scroll-with-animation的前提下  不需要过渡效果）

scroll-into-view  这个好像只能等页面渲染完成并且不滚动了之后1000ms左右  再设置才能生效   那效果可真的没法看

data: {

idd:null,

},

bindscrolltoupper: function() {

this.setData({

idd: ‘s20185’

})},

bindscrolltolower: function() {

this.setData({

idd: ‘s20185’

})},

<scroll-view scroll-y bindscrolltoupper=“bindscrolltoupper” bindscrolltolower=“bindscrolltolower” scroll-into-view="{{idd}}" style=‘height: 600rpx;’>

<view id=‘s1231’ style=‘height: 600rpx; background: red’>1</view>

<view id=‘s1231’ style=‘height: 600rpx; background: red’>2</view>

<view id=‘s20185’ style=‘height: 600rpx; background: yellow’>3</view>

<view id=‘s1231’ style=‘height: 600rpx; background: red’>4</view>

<view id=‘s1231’ style=‘height: 600rpx; background: red’>5</view>

</scroll-view>
