微信小程序实现倒计时，苹果手机不显示

JS页面代码段：

[code]const app = getApp()
let goodsList = [
{ actEndTime: '2018-07-21 21:00:34' },
{ actEndTime: '2028-07-17 21:00:37' },
{ actEndTime: '2018-09-21 05:00:59' },
{ actEndTime: '2018-08-19 07:00:48' },
{ actEndTime: '2018-08-28 03:00:11' }
]
Page({

data: {
countDownList: [],
actEndTimeList: []
},

onLoad: function () {
let endTimeList = [];
// 将活动的结束时间参数提成一个单独的数组，方便操作
goodsList.forEach(o => { endTimeList.push(o.actEndTime) })
this.setData({ actEndTimeList: endTimeList });
// 执行倒计时函数
this.countDown();
},

//当时间小于两位数时十位数补零。
timeFormat: function (param) {//小于10的格式化函数
return param < 10 ? '0' + param : param;
},

//倒计时函数
countDown: function () {
// 获取当前时间，同时得到活动结束时间数组
let newTime = new Date().getTime();//当前时间
let endTimeList = this.data.actEndTimeList;//结束时间的数组集合
let countDownArr = [];//初始化倒计时数组

// 对结束时间进行处理渲染到页面
endTimeList.forEach(o => {
let endTime = new Date(o).getTime();
let obj = null;
// 如果活动未结束，对时间进行处理
if (endTime - newTime > 0) {
let time = (endTime - newTime) / 1000;
// 获取天、时、分、秒
let day = parseInt(time / (60 * 60 * 24));
let hou = parseInt(time % (60 * 60 * 24) / 3600);
let min = parseInt(time % (60 * 60 * 24) % 3600 / 60);
let sec = parseInt(time % (60 * 60 * 24) % 3600 % 60);
obj = {
day: this.timeFormat(day),
hou: this.timeFormat(hou),
min: this.timeFormat(min),
sec: this.timeFormat(sec)
}
} else {//活动已结束，全部设置为'00'
obj = {
day: '00',
hou: '00',
min: '00',
sec: '00'
}
}
countDownArr.push(obj);
})
//每隔一秒执行一次倒计时函数， 渲染
this.setData({ countDownList: countDownArr })
setTimeout(this.countDown, 1000);
}
})
