Objective-C, which is based on the C language and uses a large library called Cocoa, is one of the older programming languages that is still being used today. Due to its age, Objective-C is more complex than languages such as Ruby and Python, but is still the language of choice for Apple applications. This Lynda.com online video will let you confidently approach a discussion of Objective-C, which is critical for developer and programming foundations.
Objective-C is one of the older languages on the list.…Invented in the early 80s as an object oriented version of C, it really is the C…language with some extra stuff added to it.…That extra stuff makes it object-oriented.…The way it's used these days one of the benefits of using Objective-C is it…comes with a large library referred to as Cocoa which we will talk about in a moment.…It is a compiled language.…Not interpreted and not one that uses intermediate bytecode.…
And although, it's a high-level language, it is one where you need to be a bit…more aware about memory management than things like Java or the .NET languages.…It uses something called reference counting, where we keep track of the objects…that we create and whether we're done with them or not.…Although advances in the language means that this is becoming less and less of…an issue, but because of that I wouldn't say it's a particularly friendly…language for beginners.…You really need kind of an intermediate level of skill to be messing with Objective-C.…
