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).
