How do I transpose a view's frame to it's superview?

Question

Not even sure how to ask this. Transpose local coordinates to global?

Answer 1

The UIView class has a handful of methods for converting coordinates of CGPoints or CGRects from one view to another. Take a look at convertPoint:toView:, convertPoint:fromView:, etc in the UIView class reference.

You can convert coordinates from one view to another or from any view to the window or vice versa.
