macOS the difference between mac and iphone - loading process

[Howiieque]

hi everyone.
both UIView and NSView conform to the NSCoding Protocol.

i subclass both of them and make a instance in the IB respectively in two projects.

mac:
1. initWithFrame: was invoked
2. awakeFormNib: was invoked
(initWithCoder: was NOT)

iphone:
1. initWithCoder: was invoked
2. awakeFromNib: was invoked
(initWithFrame: was NOT)

i think the iphone loading process makes sense. since the view is stored in the nib file, when it get unarchived, initWithCoder: is get caller.
could someone explain the difference.
thank you in advance.

It's documented here (go down to the The Object Loading Process section):
http://developer.apple.com/mac/libr...ual/LoadingResources/CocoaNibs/CocoaNibs.html

My guess is they kept it consistent in UIKit because it was new. AppKit can't have such drastic changes as it would probably break the majority of apps out there.

thank you very much. especially the recommendation of The Object Loading Process section. things are so much clear now.
