Objective-C and C++ are very different apart from their C ancestry. C++ doesn't make an especially good Obj-C replacement, and Obj-C is probably no better at the situations where C++ excels than raw C. Objective-C is a higher-level, dynamic-ish, highly-OO extension to C. (great for GUIs, not so great for writing drivers) C++ is quite low level, not dynamic at all, and not overly OO. C++ is very expressive in many situations due to its generic and automatic resource management features, which Obj-C lacks completely. (GUI code is typically horrendous, driver writing is nicer than in C)
