This Objective-C method takes two parameters.
replaceSubview is the method name
oldView is the first parameter name.
What is 'with' and 'newView'?
Thanks for help and time.
It must take two parameters, replacing the first parameter in the object with the second parameter. It seems a peculiar method to write, passing a value which might or might not be a field of your object already, then another value to replace it with which might already be a field of your obect (or might not).
