I’m reading a post about iPhone programming and I’ve noticed that the talk about Objective C++, the code shown in the post looks mainly like Objective-C but there also are several snippets in C++. Is it really possible to program Cocoa from C++?
In addition to the other comments, I would add that Objective-C++ is not exactly the same as ‘program Cocoa from C++’ because there is no C++ to Cocoa bridge involved.
In Objective-C++, you program the Cocoa API entirely with Objective-C objects/syntax. The Cocoa API remains unchanged, so you need to communicate with it in the same way (using Objective-C strings, Objective-C arrays and Objective-C objects).
The difference with Objective-C++, compared to plain Objective-C, is that you can also use C++ objects (containing Objective-C objects, contained by Objective-C objects or just along-side Objective-C objects).
