09-Sep-2015Objective-C is a very dynamic language. Its dynamism frees a program from compile-time and link-time constraints and shifts much of the responsibility for symbol resolution to runtime, when the user is in control. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime.
Objective-C is more dynamic than other programming languages because its dynamism springs from three sources:
Dynamic typing—determining the class of an object at runtime
Dynamic binding—determining the method to invoke at runtime
Dynamic loading—adding new modules to a program at runtime
