Re: [xmlvm-users] iOS 4 and new API

[Arno P. <ar...@pu...>]

Apple advocates universal binaries that can be deployed on all their 
devices and recommends to use runtime checks to see if certain 
capabilities are present on the current device:
http://developer.apple.com/iphone/library/documentation/General/Conceptual/iPadProgrammingGuide/StartingYourProject/StartingYourProject.html

Check section called "Adding Runtime Checks for Newer Symbols".

Well, we can mimic just the same in the Java API. 
Class.forName("UISplitViewController") will return null if not executed 
on an iPad.

Anyways, another issue I wanted to raise: there is more and more API 
being added and it incurs a lot of work to include Java versions for 
XMLVM because the wrappers are manually written. I think we should take 
a more serious look at projects such as 
http://code.google.com/p/jnaerator/ and consider to generate the 
wrappers automatically.

Comments?
