6. Objective-C • Superset of ANSI-C • Supports C and C++ code .h – header files .m – Objective C and/or C code .mm C/C++/Obj-C code

7. Classes • Objective C is object-oriented • Classes specified using an interface and an implementation

8. Methods • A class in Objective-C can declare two types of methods: instance methods and class methods. • An instance method is a method whose execution is scoped to a particular instance of the class. • Class methods, by comparison, do not require you to create an instance (i.e. static methods)

9. Messaging • When you want to call a method, you do so by messaging an object. • A message is the method signature, along with the parameter information the method needs. • All messages you send to an object are dispatched dynamically. • Messages are enclosed by brackets ([ and ]). • Inside the brackets, the object receiving the message is on the left side and the message (along with any parameters required by the message) is on the right.

10. Messaging Example • For example, to send the insertObject:atIndex: message to an object in the myArray variable, you would use the following syntax: [myArrayinsertObject:anObject atIndex:0]; • Objects can be nested: [[myAppObjecttheArray] insertObject:[myAppObjectobjectToInsert] atIndex:0]; • Obj-C also supports dot syntax: myAppObject.theArray = aNewArray;

12. NSString • The NSString class provides an object wrapper for strings that has all of the advantages you would expect, including built-in memory management for storing arbitrary-length strings, support for Unicode, printf-style formatting utilities, and more. • Because such strings are used commonly though, Objective-C provides a shorthand notation for creating NSString objects from constant values.
