Re: [xmlvm-users] Define the layerClass on UIView

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

checkout trunk/crossmobile, then look for a file called advisor.xml. In 
that file do a grep on "toString". This is an example on how a method 
toString() is injected to class NSString. You should be able to do the 
same for a method called layerClass. Once you have done that, do a "ant 
gen-xmlvm-ios" in crossmobile. This will re-generate the iOS API in 
../xmlvm. For this to work you need to point property sdk.path in 
xmlvm.properties to an installation of the iOS 4.3 SDK (note that 
crossmobile cannot deal with 5.* API yet).
