微信小程序适配iphoneX

// 在app.js中判断是否是哪种设备
globalData: { 
  isIphoneX: false, 
  userInfo: null 
}, 
onShow:function(){ 
  let  that = this; 
  wx.getSystemInfo({ 
    success:  res=>{ 
      // console.log(‘手机信息res‘+res.model) 
      let modelmes = res.model; 
      if (modelmes.search(‘iPhone X‘) != -1) { 
        that.globalData.isIphoneX = true 
      } 
    } 
  }) 
},

<view class=‘contentView‘ style=‘padding-bottom:{{btuBottom}}‘>
       <button class=‘but‘>Button </button>
</view>

data: {
  btuBottom:"";
  },
//在这里只需要判断是不是iphonex，然后设置下padding-bottom:即可
  onLoad: function (options) {
    let isPhone = app.globalData.isIphoneX;
    if(isPhone){
      this.setData({
        btuBottom:"68rpx",
      })
    }
}
