Hi!
I totally agree that it is a little confusing. But #new an #new(owner) are two different methods, especially in Obj-C.
Calling A.new(arg) cannot call -init, since -init doesn't take any argument, so it will call any initializer method that takes one argument :-).
This is why:
class A; def initialize; end; end; # Will never be called with A.new, because -init will be called instead
class A; def initialize(str); end; end; # Will be called with A.new(str), because -init cannot be called
It simply depends on how you define your initilizer method :-)

This is only true if you follow objc init I think... for example...
I came across this problem with NSWindowController and it took me a while to figure out.
class PasswordController < NSWindowController
def initialize
initWithWindowNibName("Password") ##FAIL Never called! init called instead
end
class PrefController < NSWindowController
def initialize(owner)
@owner = owner
initWithWindowNibName("Preferences")
end
end
The first example fails and so I finally got that I needed the init method to make the window appear but I couldn't figure out why the second option worked.
Must have been a long day but clearly if designate an initialize with a param init is bypased...
so if I take the
class A <String
def initialize(b)
super
end
end
example and do A.new("hi there") gives
initialize
=> "hi there"
so what is going on? I think there might need to be some clarity.....
