Brad,
I've been making a similar transition back to Objective-C/Cocoa after
8+ years away. Firstly, this is not the appropriate list for iPhone
specific questions. If you log into the iPhone dev center( http://developer.apple.com/iphone)
, there is a link to the iPhone developer forums beta. I would highly
suggest you browse the posts there and repost your question from here
to the appropriate forum (there are lots of subcategories). There are
also other websites with additional examples/forums (Eg. http://www.iphonedevsdk.com
).
That being said, having beat my head into the wall for a bit, trying
to figure things out, I have to say just keep RTFM'ing. Apple has
actually provided quite a good amount of documentation. I would
recommend thoroughly reading all of the guides on the iPhone dev
center home page (after you've logged in) and then looking at as many
examples as possible.
One XCode specific tip that I find very helpful is, if you have a
class, say UINavigationController, in your code, select the text
(UINaviagationController in this case), right click, and choose Find
Selected Text in Documentation. This will bring up the XCode doc
window and show you all occurrences of that text in the doc. This
will typically point you to guides, examples, and class doc.
I'm sorry that I haven't answered your specific question, but I can
say that I too have gotten myself in some knots as I come up to speed
(and it's definitely frustrating not having source code like you do
with Java), but stick with it, and you'll get through it.

Apologies if this appears twice; Entourage is acting up...
After years of Java/Swing/Web (and far too many away from ObjC ;), I'm
having a real struggle getting oriented to iPhone's way of doing
things. Can
someone please help me get started?
I'm building a navigation based application (I think ;) by following
this:
http://theappleblog.com/2009/04/15/iphone-dev-sessions-create-a-navigation-b
ased-application/ Call that with its several subpanes Pane2.
So far so good; I have that much working. I also have another project
with a login pane (Pane1), and several others with other panes I
need for
the full app. (Pane 2-n). No app content for now; I simply need to
navigate
between non-homogeneous panes.
Problem is, how the heck to sew this stuff together? Login pane
first, then
Pane2 on clicking the OK button, then Pane3 on selecting one of the
Pane2
rows, and so forth?
Then Pane2 needs to collect a set of on/off options for each of its
rows.
I've been trying to use the first example from the UIControls
sampler (in
ControlsViewController; the one with the slide switch) for that. But
running
into much the same problems; lack of the "big picture" about how all
these
tutorials and documents tie together.
Can someone please help? Thanks!
PS: Current problem is an infinite loop where [CALayer sublayers]
calls
[UIViewHierarchy
makeSubtreePerformSelector:withObject:withObject:copySublayers:]
forever.
Probably due to the same thing; lack of understanding how interface
builder
operations relate to the code.
