Creating new NSFileManager

[mrf]

Hello,

I've read through most of the book and must say it's excellent!

I've just started the 16th chapter. The first page describes how to create a new File Manager object

Code: (Objective-C)

[NSFileManager defaultManager]

What I don't understand is why the alloc "message" is not called here, like the previous chapters have talked about? I tried creating the object using

Code: (Objective-C)

[[NSFileManager alloc] init]

and that seems to do the same thing?

I also noted the same thing in the chapter about NSArray, where the code

Code: (Objective-C)

[NSArray array]

is used?

I'm sure there's a logic explanation to this, tho I have not found it explained in the book so far?
