Objective-C is organized as a series of object-oriented additions to the C language. It is important to remember that it is the ANSI C language at its core. In a typical Objective-C program, segments of traditional C are organized into strips of code and associated data which are executed under tightly constrained conditions.

Apr 23, 2013 · Much of object-oriented programming consists of writing the code for new objects—defining new classes. In Objective-C, classes are defined in two parts: An interface that declares the methods and properties of the class and names its superclass. An implementation that actually defines the class (contains the code that implements its methods)

An argument is a value that you pass into the method. To call an Objective-C method with no arguments, the syntax is [object methodName] To call a method with one argument, the syntax is [object methodName:arg1] To call a method with two arguments, the syntax is [object methodName:arg1 andName:arg2] And so on. The Objective-C declared properties feature provides a simple way to declare and implement an object’s accessor methods. Overview. You typically access an object’s properties (in the sense of its attributes and relationships) through a pair of accessor (getter/setter) methods.

In Objective-C, how do I call an object's super class method? For example, lets say I have an instance of an object "foo". "foo" has a method that is overriden. I do not want to call this overriden method. Instead, I want to call the original method on the foo object instance. You cannot do: [[instance super] super_method]; as far as I am aware
