FWIW, I have written major parts of an app in C++ and had no problems. There are two things to keep in mind,
The rules for memory management are different. Don't confuse them.
A C++ object is different from an Obj-C object. Don't confuse the access rules.
Otherwise, everything works. You can put an OC method call into C++ code and so forth. I made great use of NSString methods in C++ code, for example.

The previous person (a Window's programmer) decided it was a good idea to develop a core "engine" (15 source files out of a total of 60) in C++ on windows and then move onto the Mac/XCode 3 and "bend" the project settings to suit it. Also where there is Objective-C code it doesn't conform to the Cocoa guide lines and some it has been made to "look" like C++, things like this:
