检测设备是否为iOS

以上所有答案都不适用于所有版本的iOS(包括iOS 13)上的所有主要浏览器。下面是一个适用于所有iOS版本的Safari、Chrome和Firefox的解决方案:

var isIOS = (function () {
    var iosQuirkPresent = function () {
        var audio = new Audio();

        audio.volume = 0.5;
        return audio.volume === 1;   // volume cannot be changed from "1" on iOS 12 and below
    };

    var isIOS = /iPad|iPhone|iPod/.test(navigator.userAgent);
    var isAppleDevice = navigator.userAgent.includes('Macintosh');
    var isTouchScreen = navigator.maxTouchPoints >= 1;   // true for iOS 13 (and hopefully beyond)

    return isIOS || (isAppleDevice && (isTouchScreen || iosQuirkPresent()));
})();

请注意，此代码片段的编写优先考虑的是可读性，而不是简洁性或性能。

解释:

If the user agent contains any of "iPod|iPhone|iPad" then clearly the device is iOS. Otherwise, continue... Any other user agent that does not contain "Macintosh" is not an Apple device and therefore cannot be iOS. Otherwise, it is an Apple device, so continue... If maxTouchPoints has a value of 1 or greater then the Apple device has a touch screen and therefore must be iOS since there are no Macs with touch screens (kudos to kikiwora for mentioning maxTouchPoints). Note that maxTouchPoints is undefined for iOS 12 and below, so we need a different solution for that scenario... iOS 12 and below has a quirk that does not exist in Mac OS. The quirk is that the volume property of an Audio element cannot be successfully set to any value other than 1. This is because Apple does not allow volume changes on the Audio element for iOS devices, but does for Mac OS. That quirk can be used as the final fallback method for distinguishing an iOS device from a Mac OS device.

iOS设备上的用户代理会显示iPhone或iPad。我只是根据这些关键词进行筛选。

如果你正在使用React，有一个很棒的库可以解决这类问题:React - agent。(使用ua-parser-js构建。)

https://github.com/medipass/react-ugent

可用的浏览器有:

Chrome, chromium, edge, firefox，即，lynx, safari, opera

可用的操作系统包括:

安卓，黑莓，铬操作系统，debian, ios, linux, MAC操作系统，ubuntu, unix, Windows

可选设备包括:

游戏机、电脑、手机、平板电脑、智能电视、可穿戴、嵌入式

易于使用:

<Ugent browser="safari" os="ios">
  <div>
    This text only shows on Safari on iOS.
  </div>
</Ugent>

如果你不使用React，你可以使用- ua-parser-js

在添加Modernizr测试时，只要有可能，您应该添加针对某个特性的测试，而不是针对某个设备或操作系统。如果需要的话，为iPhone添加10个测试并没有什么错。有些东西就是不能被特征检测到。

    Modernizr.addTest('inpagevideo', function ()
    {
        return navigator.userAgent.match(/(iPhone|iPod)/g) ? false : true;
    });

例如，在iPhone(不是iPad)上，视频不能在网页上内联播放，它会全屏打开。所以我创建了一个测试" no-inpage-video "

然后你可以在css中使用它(Modernizr添加类.no-inpagevideo到<html>标签如果测试失败)

.no-inpagevideo video.product-video 
{
     display: none;
}

这将隐藏iPhone上的视频(我在这种情况下实际做的是显示一个可供选择的图像，点击播放视频-我只是不想显示默认的视频播放器和播放按钮)。

我在几年前写过这个，但我相信它仍然有效:

if(navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.match(/iPhone/i) || (navigator.userAgent.match(/iPod/i))) 

    {

        alert("Ipod or Iphone");

    }

else if (navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.match(/iPad/i))  

    {

        alert("Ipad");

    }

else if (navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.indexOf('Safari') != -1)

    {

        alert("Safari");

    }

else if (navigator.vendor == null || navigator.vendor != null)

    {

        alert("Not Apple Based Browser");

    }
