iPad 检测

您应该能够通过查看 userAgent 属性：

var is_iPad = navigator.userAgent.match(/iPad/i) != null;

iPhone/iPod 检测

同样，userAgent 属性：iPhone/iPod 检测 org/en-US/docs/Web/API/NavigatorID/platform" rel="noreferrer">platform 属性来检查 iPhone 或 iPod 等设备：

function is_iPhone_or_iPod(){
     return navigator.platform.match(/i(Phone|Pod))/i)
}

注释

，但您通常应该避免执行特定于浏览器的检测，因为它通常不可靠（并且可能被欺骗）。最好使用实际的功能检测< /a> 在大多数情况下，这可以通过像 Modernizr 这样的库来完成。

正如 Brennen 的回答中指出的，在 Facebook 应用程序中执行此检测时可能会出现问题。请参阅他处理这种情况的答案。

iPad Detection

You should be able to detect an iPad user by taking a look at the userAgent property:

var is_iPad = navigator.userAgent.match(/iPad/i) != null;

iPhone/iPod Detection

Similarly, the platform property to check for devices like iPhones or iPods:

function is_iPhone_or_iPod(){
     return navigator.platform.match(/i(Phone|Pod))/i)
}

Notes

While it works, you should generally avoid performing browser-specific detection as it can often be unreliable (and can be spoofed). It's preferred to use actual feature-detection in most cases, which can be done through a library like Modernizr.

As pointed out in Brennen's answer, issues can arise when performing this detection within the Facebook app. Please see his answer for handling this scenario.

尽管接受的解决方案对于 iPhone 来说是正确的，但它会错误地声明 isiPhone 和 isiPad 对于通过 Facebook 应用在 iPad 上访问您网站的用户来说是正确的。

传统观点认为 iOS 设备有一个 Safari 用户代理和一个 UIWebView 用户代理。这种假设是不正确的，因为 iOS 应用程序可以并且确实自定义其用户代理。这里的主要罪犯是Facebook。

比较 iOS 设备中的这些用户代理字符串：

# iOS Safari
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
iPhone: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

# UIWebView
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

# Facebook UIWebView
iPad: Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; ru_RU) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1;FBBV/4100.0;FBDV/iPhone3,1;FBMD/iPhone;FBSN/iPhone OS;FBSV/5.1.1;FBSS/2; tablet;FBLC/en_US]

请注意，在 iPad 上，Facebook UIWebView 的用户代理字符串包括“iPhone”。

在 JavaScript 中识别 iPhone / iPad 的旧方法：

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);

如果您采用这种方法来检测 iPhone 和 iPad，那么如果用户来自 Facebook，您最终会得到 IS_IPHONE 和 IS_IPAD 均为 true一个iPad。这可能会产生一些奇怪的行为！

在 JavaScript 中识别 iPhone / iPad 的正确方法：

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = (navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);
if (IS_IPAD) {
  IS_IPHONE = false;
}

我们在 iPad 上声明 IS_IPHONE 为 false，以掩盖奇怪的 Facebook UIWebView iPad 用户代理。这是用户代理嗅探如何不可靠的一个例子。自定义用户代理的 iOS 应用程序越多，用户代理嗅探的问题就越多。如果您可以避免用户代理嗅探（提示：CSS 媒体查询），那就这样做。

Although the accepted solution is correct for iPhones, it will incorrectly declare both isiPhone and isiPad to be true for users visiting your site on their iPad from the Facebook app.

The conventional wisdom is that iOS devices have a user agent for Safari and a user agent for the UIWebView. This assumption is incorrect as iOS apps can and do customize their user agent. The main offender here is Facebook.

Compare these user agent strings from iOS devices:

# iOS Safari
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
iPhone: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

# UIWebView
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

# Facebook UIWebView
iPad: Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; ru_RU) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1;FBBV/4100.0;FBDV/iPhone3,1;FBMD/iPhone;FBSN/iPhone OS;FBSV/5.1.1;FBSS/2; tablet;FBLC/en_US]

Note that on the iPad, the Facebook UIWebView's user agent string includes 'iPhone'.

The old way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);

If you were to go with this approach for detecting iPhone and iPad, you would end up with IS_IPHONE and IS_IPAD both being true if a user comes from Facebook on an iPad. That could create some odd behavior!

The correct way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = (navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);
if (IS_IPAD) {
  IS_IPHONE = false;
}

We declare IS_IPHONE to be false on iPads to cover for the bizarre Facebook UIWebView iPad user agent. This is one example of how user agent sniffing is unreliable. The more iOS apps that customize their user agent, the more issues user agent sniffing will have. If you can avoid user agent sniffing (hint: CSS Media Queries), DO IT.

我用这个：

function fnIsAppleMobile() 
{
    if (navigator && navigator.userAgent && navigator.userAgent != null) 
    {
        var strUserAgent = navigator.userAgent.toLowerCase();
        var arrMatches = strUserAgent.match(/(iphone|ipod|ipad)/);
        if (arrMatches != null) 
             return true;
    } // End if (navigator && navigator.userAgent) 

    return false;
} // End Function fnIsAppleMobile


var bIsAppleMobile = fnIsAppleMobile(); // TODO: Write complaint to CrApple asking them why they don't update SquirrelFish with bugfixes, then remove

I use this:

function fnIsAppleMobile() 
{
    if (navigator && navigator.userAgent && navigator.userAgent != null) 
    {
        var strUserAgent = navigator.userAgent.toLowerCase();
        var arrMatches = strUserAgent.match(/(iphone|ipod|ipad)/);
        if (arrMatches != null) 
             return true;
    } // End if (navigator && navigator.userAgent) 

    return false;
} // End Function fnIsAppleMobile


var bIsAppleMobile = fnIsAppleMobile(); // TODO: Write complaint to CrApple asking them why they don't update SquirrelFish with bugfixes, then remove
