判断终端是ios还是安卓的一些妙用（附加微信分享图标修改）

最近遇到一个项目 要求有两个icon（就是下载地址 下载安卓的apk  和ios的安装包）

 一开始的方案是 什么设备都显示这两个icon 但是后来老大说这样不好   安卓用户给他下载ios 也不行  ios下载安卓也不行 于是就想到了一个办法 （判断终端）

于是百度了一些 经测试是可以完成的

复制代码
var u = navigator.userAgent, app = navigator.appVersion;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1; //android终端或者uc浏览器
var isiOS = !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
    if(isAndroid){
        $(".down0").css('display','none')
    }else if(isiOS){
        $(".down").css('display','none')
    }
    else{
        return false;
    }
复制代码

判断微信：

	function isWeiXin(){
				    var ua = window.navigator.userAgent.toLowerCase();
				    if(ua.match(/MicroMessenger/i) == 'micromessenger'){
				        return true;
				    }else{
				        return false;
				    }
				}

　　

代码如下 应该都看得懂吧。。。。  这样的话什么设备就针对什么设备显示icon   完美。。。

当你的才华撑不起你的野心的时候、请潜下心、低下头、好好学习、
 
 
现有需求：判断IOS，安卓，点击下载判断：
奇葩：小米note 用上面的判断方法显示是他妈IOS，所以
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1|| u.indexOf('MI') > -1|| u.indexOf('XiaoMi') > -1; //android终端或者uc，小米浏览器
不是安卓就是IOS，上面的IOS判断不准确
