C and Objective-C have many differences.
First of all, C is procedure-oriented language while object-C is object-oriented language.
They have different syntaxes.
Objective-C is more familiar to smalltalk than C/C++.
e.g. of calling method
c: foo(param1, para2, ...);
objective-c: [object foo:param];
There are many differences between two languages.
hey all. i have an UIWebView(tarayici in my situation) in view controller. it works fine when its scroll view delegate is not assigned to view controller. but i need to know when it is scrolled that is why i wrote this code.
self.tarayici.scrollView.delegate = self;
but when i write this down then webview acts so weird. for example after this code when i want to scroll then it scrolls only once if i make 3 or 4 attempts. so how can make it work more efficient with that code ?
i think i found the solution. The commented UIview animation block locked the main thread i think that is why Scroll View couldnt response to the new touches. but with this new animation block it works well.
All of your questions really depend on what you are trying to accomplish when programming in Objective-C. If you are just using it as a language the answer is yes you can program with it on windows and linux.
However if you are looking to develop with the Cocoa frameworks and/or for iOS platforms then you will need:
1 - Apple hardware (mini, macbook, iMac, Pro)
2 - XCode will be the IDE that you most likely will want to start with if you are new and learning.
3 - You can get XCode from the App Store on your OSX machine.
Do you understnad the principles of the product you want to create? Are you a skilled OSX programmer, etc.?

If you need to ask this question then the chances are that your understanding of OSX is not yet at the right level. I would suggest finding some study materials that give details of the operating system internals so you can gain a good understanding of how it all fits together.
I have experience with Objective-C and iOS development, but slightly new to OSX. Windows OS has a really good api for its Windowing system, whereas Quartz has an API but it is significantly limited in comparison. I'm looking to replicate the functionality of the Windows API in OSX, (specifically window-level controls), but it looks like all Window/Visual commands are handled through Quartz Compositor.
If I can rewrite/extend/reverse engineer that module, I may be able to get the APIs I need.
