I'm developing GUI apps on Mac. I have been using C++ for 10+ years. Do I need to switch to Objective C?

I'开发者_运维问答ve been coding on C++/Linux for 10+ years.

I am switching to do Mac development.

My development involves GUI components.

Is my only choice to learn Cocoa/Objective-C, or is there a way to wrap Cocoa and use it from C++ land?

Thanks!

Yes, you need to learn Objective-C. Besides, you wouldn't gain much if you didn't need to. It's not the language that's hard to learn but the Cocoa framework (not because it's inherently hard but because it's so huge).

You could use Carbon, but that's deprecated.

As Ole says, Objective-C is not hard to learn if you have a C++ background - and you can mix the languages if you use Objective-C++ (which can be useful, but usually best to partition the code that uses different languages - so use Objective-C/ Cocoa for the GUI layer and C++ for the core logic. I do it this way in my iPhone game, vConqr).

If you've done GUI work in C++ I think you'll appreciate why Objective-C was chosen for Cocoa. It's very nice for event driven designs and has a number of abstractions that are a natural fit. As you get into more abstract areas, though, especially if you use a lot of containers and algorithms, you'll probably start to find the limitations a little annoying. But give it time - there are other useful abstractions that are not immediately obvious (dynamic typing, key/ value coding and other forms of reflection, categories...).

You might also find this stackoverflow question useful.

No, I don't think you need to learn Objective-C. You can use Qt framework to develop applications on Mac using C++.

If you are only going to work on Mac apps, then learn Objective-C and the Cocoa frameworks. Cocoa apps can pick up new features "for free" in newer Mac OS X releases, and will be more future-proof than a cross-platform app framework like Qt.

There are so many aspects to Cocoa frameworks (collectively) that you would be best served by sticking to the native app framework to serve your customers (end users). That is really what matters, not the short term inconvenience of learning a new language or framework (which comes with the job, adapt or die).

Pretty soon you will be as frustrated with Xcode as the rest of us.

I use WxWindows on the Mac for my tool development. Took a little bit of working but I got my Jam based c++ pipeline that I use on windows working perfectly. The only thing you need to remember to get it all correctly working is to create the proper application rules... easy to get working as a jam rule.

As mentioned in a few of the other answers, there are a number of cross platform GUI libraries that support mac. Such as Qt and WxWindows. You can use any of them, I personally have only used Qt and found it quite pleasurable to work with after coming from Java and C toolkits.

In order to use the native GUI libraries, you can use Python as well (PyObjC). Java is also able to make native looking apps in OS X.
