This uses a combination of window.navigator.userAgent and window.navigator.standalone. It can distinguish between all four states relating to an iOS web app: safari (browser), standalone (fullscreen), uiwebview, and not iOS.

Demo: http://jsfiddle.net/ThinkingStiff/6qrbn/

var standalone = window.navigator.standalone,
    userAgent = window.navigator.userAgent.toLowerCase(),
    safari = /safari/.test( userAgent ),
    ios = /iphone|ipod|ipad/.test( userAgent );

if( ios ) {
    if ( !standalone && safari ) {
        //browser
    } else if ( standalone && !safari ) {
        //standalone
    } else if ( !standalone && !safari ) {
        //uiwebview
    };
} else {
    //not iOS
};

User Agents

Running in UIWebView
Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176

Running in Safari on 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

Running in Safari on Mac OS X
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.55.3 (KHTML, like Gecko) Version/5.1.5 Safari/534.55.3

Running in Chrome on Mac OS X
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.151 Safari/535.19

Running in FireFox on Mac OS X
Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:11.0) Gecko/20100101 Firefox/11.0

Detection Code

var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);
var is_safari_or_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit/i.test(navigator.userAgent);

I think that you can just use the User-Agent.


UPDATE

Page browsed using iPhone Safari

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8B117 Safari/6531.22.7

I will try in a second with UIWebView

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

The difference is that the Safari one says Safari/6531.22.7


Solution

var isSafari = navigator.userAgent.match(/Safari/i) != null;

Yeah:

// is this an IPad ?
var isiPad = (navigator.userAgent.match(/iPad/i) != null);

// is this an iPhone ?
var isiPhone = (navigator.userAgent.match(/iPhone/i) != null);

// is this an iPod ?
var isiPod = (navigator.userAgent.match(/iPod/i) != null);

I know this code will check if it is being accessed from an icon added to the home screen:

if (window.navigator.standalone == true) {
//not in safari
}

but I'm not sure how it would react in a UIWebView. The only other solution I could think of is getting the user agent or using - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType and replacing the query string of the page you are accessing with something the page uses to identify that it is being accessed from a web view.

Neoneye's solution does not work anymore (see comments) and can be simplified. On the other hand, testing only "Safari" in the UA adresses much more than the ios handheld devices.

This is the test i'm using :

var is_ios = /(iPhone|iPod|iPad).*AppleWebKit.*Safari/i.test(navigator.userAgent);

I don't think there's anything specific you can use in client-side Javascript, but if you have control over what the originating UIWebView can do, you might want to consider playing with the user agent string it generates, and testing for that in your client-side Javascript instead? A bit of a hack I know, but hey… This question may give some pointers on tweaking the user agent:

@ Sod, Well i don’t have answer, but i am not convinced why you want to check, Since, browser engine whether its safari ( Browser ) or Application will be same its Webkit only, Yes Application can configure the Browser engine capabilities like, whether application wants to run JS or Display Image etc…

I believe, you must check for certain property whether Flash supported by Browser or whether browser displays image or not, or probably may be you would like to check the screen size,
