That's odd, when I search iPhone + NDA on this list a got a lots of
answer like thoses ones:
“As ever, the iPhone SDK is under the NDA you agreed to. You cannot
discuss it here.”
“This is the point where we slam up hard against the non-disclosure
agreement to which we all had to agree to even know that video
existed, much less access it. As has been beaten to death on this list
many times before (is there even anything left of that carcass any
more?), we can't discuss that here.”
“iPhone SDK is under NDA (non-disclosure agreement) and cannot be
discussed via a channel such as this list.”
And a lot of others like this.
Try to create a simple Xcode / Cocoa (not Cocoa touch) project at
first. It's very similar and you may get some help from people here.

Hi Jean,
Merci!
I tried to rename it to Adder.mm, also tried to rename my
viewcontroller to viewcontroller.mm, it didn't work. I searched
google, ADC, and cocoadev.com, and really couldn't find an answer.
Cheers,
Tang

Hi,
I'm new to iphone os programming and my project involves to build c+
+ files
within the xcode cocoa touch environment.
So i tried to create a new cocoa touch project and use the interface
builder
to add a button and a label.
So that when i press the button, the label would show the result of
the
"add()" method i call from the following c++ file.
I then add a new c++ file called Adder.cpp which looks like this:
class Adder{
public:
Adder();
int add(int x,int y){
return x+y;
}
};
Simple enough, following the example i found from
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Articles/chapter_12_section_3.htm
The first thing to do it to learn how to search the mailine list
archive. For example try to search for iPhone and NDA:
http://www.cocoabuilder.com/search/archive/cocoa?words=iphone+nda
Then try to compile your file as an obj-c++ file and not as a C++
file. To do this, rename it using the .mm extension (instead of .m
or .cpp).
