frame is the property you are looking for, it gives you the origin and size of a view, relative to its superview

UIView *a = //outer view
UIView *b = //inner view
[a addSubview:b];

CGRect bFrame = b.frame; 
NSLog(@"%@", NSStrinFromCGRect(bFrame)); //will be something like (100, 100, 40, 20)

edit: I didnt realise they werent subviews (I dont use IB), so you will need to convert to the coord system of a:

   CGRect bFrame = [a convertRect:b.frame fromView:b.superView];

to know the position of a view respect another one use [aView convertPoint:toView:] or [aView convertRect:toView:], you can find the documentation of this functions here and here.
