Is it possible and how to create objects of such classes like NSString from C++ code?
You’ve got 3 options:
1) If you’re mainly writing in C++ and want to communicate with an API that expects cocoa strings and collections, then Core Foundation is a C (and therefore C++) api for creating and interacting with many of Foundation’s classes. Many NS-prefixed cocoa classes have a CF-prefixed equivalent, and can be used interchangeably.
2) If you’re integrating c++ code with objective-c code, then you have the option of compiling the interface classes as objective-c++ which allows you to mix both in the same source file. So it’s valid to do stuff like
vector.push_back( [NSString stringWithFormat:@"string"] )3) It is possible to access (near enough) the whole objective-c language as a C runtime library by including
<objc/runtime.h>. I can’t actually think of a good reason for using this over one of the other 2, but it might be worth keeping in mind if there’s a good reason you can’t.
