Code conditional on iOS

[Kyle Baley]

Is there a non-JSNI way of detecting whether a user is on iOS, specifically iOS 6. We had a bug introduced in our app that happens only on iOS6. It has to do with how two different panels are inserted into the DOM and whether they accept mouse down events. The method we have now works everywhere except on iOS 6 (it works on earlier versions). We have a workaround that works in iOS 6 but it has other minor quirks in the other browsers so we want to implement it only in iOS.

For now, we're using a JSNI method to retrieve the userAgent client-side. I'd like to use Deferred Binding but as far as I know, I can't use it specifically for iOS, just gecko1_8, safari, etc.

You don't need JSNI: http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/Window.Navigator.html

You can create a new binding property, there's an example at https://code.google.com/p/google-web-toolkit/wiki/ConditionalProperties#Example_2:_Avoiding_permutation_explosion
