微信小程序在ios端分享给别人时 分享卡上面没有图片
但在安卓上面图片是能显示的

onShareAppMessage: function (res) {

var that = this;
return {
  title: that.data.title,
  path: '/pages/detail/detail?id=1',
  imageUrl: that.data.img,
  success: function (res) {
    wx.showToast({
      title: '分享成功',
      icon: 'success',
      duration: 1500
    })
  },
  fail: function (res) {
    wx.showToast({
      title: '分享失败',
      icon: 'none',
      duration: 1500
    })
  }
}

}
