Detect if device is iOS

I'm wondering if it's possible to detect whether a browser is running on iOS, similar to how you can feature detect with Modernizr (although this is obviously device detection rather than feature detection).

Normally I would favour feature detection instead, but I need to find out whether a device is iOS because of the way they handle videos as per this question YouTube API not working with iPad / iPhone / non-Flash device

Detecting iOS

I am not a fan of User Agent sniffing, but here is how you would do it:

var iOS = /iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream;

Another way is relying on navigator.platform:

var iOS = !!navigator.platform && /iPad|iPhone|iPod/.test(navigator.platform);

iOS will be either true or false

Why not MSStream

Microsoft injected the word iPhone in IE11's userAgent in order to try and fool Gmail somehow. Therefore we need to exclude it. More info about this here and here.

Below is IE11's updated userAgent (Internet Explorer for Windows Phone 8.1 Update):

Mozilla/5.0 (Mobile; Windows Phone 8.1; Android 4.0; ARM; Trident/7.0; Touch; rv:11.0; IEMobile/11.0; NOKIA; Lumia 930) like iPhone OS 7_0_3 Mac OS X AppleWebKit/537 (KHTML, like Gecko) Mobile Safari/537


Easily add more devices, without using Regular Expressions:

function iOS() {

  var iDevices = [
    'iPad Simulator',
    'iPhone Simulator',
    'iPod Simulator',
    'iPad',
    'iPhone',
    'iPod'
  ];

  if (!!navigator.platform) {
    while (iDevices.length) {
      if (navigator.platform === iDevices.pop()){ return true; }
    }
  }

  return false;
}

iOS() will be either true or false

Note: Both navigator.userAgent and navigator.platform can be faked by the user or a browser extension.


Detecting iOS version

The most common way of detecting the iOS version is by parsing it from the User Agent string. But there is also feature detection inference*;

We know for a fact that history API was introduced in iOS4 - matchMedia API in iOS5 - webAudio API in iOS6 - WebSpeech API in iOS7 and so on..

Note: The following code is not reliable and will break if any of these HTML5 features is deprecated in a newer iOS version. You have been warned!

function iOSversion() {

  if (/iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream) {
    if (!!window.indexedDB) { return 'iOS 8 and up'; }
    if (!!window.SpeechSynthesisUtterance) { return 'iOS 7'; }
    if (!!window.webkitAudioContext) { return 'iOS 6'; }
    if (!!window.matchMedia) { return 'iOS 5'; }
    if (!!window.history && 'pushState' in window.history) { return 'iOS 4'; }
    return 'iOS 3 or earlier';
  }

  return 'Not an iOS device';
}
Answer

After iOS 13 you should detect iOS devices like this, since iPad will not be detected as iOS devices by old ways (due to new "desktop" options, enabled by default):

let isIOS = /iPad|iPhone|iPod/.test(navigator.platform)
|| (navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1)

The first condition for iOS < 13 or iPhone or iPad with disabled Desktop mode, the second condition for iPadOS 13 in the default configuration, since it position itself like Macintosh Intel, but actually is the only Macintosh with multi-touch.

Rather a hack than a real solution, but work reliably for me

P.S. As being said earlier, you probably should add IE checkup

let isIOS = (/iPad|iPhone|iPod/.test(navigator.platform) ||
(navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1)) &&
!window.MSStream
Answer

This sets the variable _iOSDevice to true or false

_iOSDevice = !!navigator.platform.match(/iPhone|iPod|iPad/);
Answer

If you are using Modernizr, you can add a custom test for it.

It doesn't matter which detection mode you decide to use (userAgent, navigator.vendor or navigator.platform), you can always wrap it up for a easier use later.

//Add Modernizr test
Modernizr.addTest('isios', function() {
    return navigator.userAgent.match(/(iPad|iPhone|iPod)/g);
});

//usage
if (Modernizr.isios) {
    //this adds ios class to body
    Modernizr.prefixed('ios');
} else {
    //this adds notios class to body
    Modernizr.prefixed('notios');
}

There is this custom Modernizr tests: https://gist.github.com/855078

Answer

A simplified, easy to extend version.

var iOS = ['iPad', 'iPhone', 'iPod'].indexOf(navigator.platform) >= 0;
Answer

It's probably worth answering that iPads running iOS 13 will have navigator.platform set to MacIntel, which means you'll need to find another way to detect iPadOS devices.

Answer

I wrote this a couple years ago but i believe it still works:

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");

    }
Answer

Wow, a lot of longish tricky code here. Keep it simple, please!

This one is IMHO fast, save, and working well:

 iOS = /^iP/.test(navigator.platform);

 // or, more future-proof (in theory, probably not in practice):

 iOS = /^iP(hone|[ao]d)/.test(navigator.platform);

 // or, if you prefer readability:

 iOS = /^(iPhone|iPad|iPod)/.test(navigator.platform);
  • It's fast because the regexp checks the ^starting position of the platform string first and stops if there is no "iP" (faster than searching the long UA string until the end anyway)
  • It's safer than UA check (assuming navigator.platform is less likely faked)
  • Detects iPhone / iPad Simulator


UPDATE: This doesn't cover iPad in desktop mode (and therefore default iPadOS 13).
That's fine for my usecases, if it's not for you, see Justin's and kikiwora's answers.

Answer

The user-agents on iOS devices say iPhone or iPad in them. I just filter based on those keywords.

Answer

Wherever possible when adding Modernizr tests you should add a test for a feature, rather than a device or operating system. There's nothing wrong with adding ten tests all testing for iPhone if that's what it takes. Some things just can't be feature detected.

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

For instance on the iPhone (not the iPad) video cannot be played inline on a webpage, it opens up full screen. So I created a test 'no-inpage-video'

You can then use this in css (Modernizr adds a class .no-inpagevideo to the <html> tag if the test fails)

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

This will hide the video on iPhone (what I'm actually doing in this case is showing an alternative image with an onclick to play the video - I just don't want the default video player and play button to show).

Slightly update the first answer using a more functional approach.

    const isIOS = [
      'iPad Simulator',
      'iPhone Simulator',
      'iPod Simulator',
      'iPad',
      'iPhone',
      'iPod',
    ].indexOf(navigator.platform) !== -1;
Answer

In order to detect the iOS version, one has to destructure the user agent with a Javascript code like this:

 var res = navigator.userAgent.match(/; CPU.*OS (\d_\d)/);
    if(res) {
        var strVer = res[res.length-1];
        strVer = strVer.replace("_", ".");
        version = strVer * 1;
    }
Answer

var isiOSSafari = (navigator.userAgent.match(/like Mac OS X/i)) ? true: false;

Answer

In my case the user agent was not good enought since in the Ipad the user agent was the same as in Mac OS, therefore I had to do a nasty trick:

var mql = window.matchMedia("(orientation: landscape)");

/**
 * If we are in landscape but the height is bigger than width
 */
if(mql.matches && window.screen.height > window.screen.width) {
    // IOS
} else {
    // Mac OS
}
Answer

None of the previous answers here work for all major browsers on all versions of iOS, including iOS 13. Here is a solution that works for Safari, Chrome and Firefox for all iOS versions:

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()));
})();

Note that this code snippet was written with priority on readability, not conciseness or performance.

Explanation:

  • 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.

Answer

You can also use includes

  const isApple = ['iPhone', 'iPad', 'iPod', 'iPad Simulator', 'iPhone Simulator', 'iPod Simulator',].includes(navigator.platform)
