IOSView Property Type

If I add a Public Property of type IOSView under App, then try and assign it to any View, i cant access the Methods or Controls.

app.inst_View = Nil
app.inst_View = new View1 or app.inst_View = new View2

it is not treated as an instance of the view. I need to be able to asign an Public instance to any of my View Controllers. Is this Possible?
