If a Class adopts a Protocol, it adopts all of it.Protocols do not include implementation.Like Interfaces in Java, a list of Method declarations independent of a Class.Malcolm Crawford, of Stepwise, has posted a helpful memory management article: Objects created with Convenience will be collected automatically unless you Retain them. When you finish with an object, you must release it. Memory managementĪpple's implementation of Objective-C does not include garbage collection. UI objects are subclasses of NSControl (and can be set in IB orĮach class has one designated initializer all other init.Selectors Identify (select) method implementation.An outlet is an instance variable pointing to a UI object.Basic design principle is that of Model - View - Controller.

Objective-C uses a header file and implementation file:

Expressions are contained within square brackets.

Some aspects of the Objective-C implementation are inspired by Smalltalk. Objective-C is native to Cocoa, but it is not unique to Cocoa. The UI widgets, or "NSControls" objects also have a "cell," separate from the UI. The message "knows" who or what "sends" it. Target: The object to which a message will be sent when a given widget is activated by a user.Īction: The message the widget sends when it is activated. The design principle behind Cocoa functionality is Target-Action - it is the basis for message sending.

Interface builder does not create code - technically it creates "serialized objects." It also includes "palettes" containing UI interface elements. Interface Builder includes "style guides" for the GUI, lines indicating regions and borders for layout and aligning elements. Interface Builder (IB) is the interface design environment for Cocoa, it provides drag and drop functionality for creating the GUI, and helps developers adere to the HIG or Human Interface Guidelines.

They are also portable and reusable check out the Nib Tool. nib files, which "point" to resources in the OS, and are thus much smaller than they might otherwise be.

Nib files are "a statically stored representation of the set of interface objects used by the application and their relationships which can be efficiently brought into memory when needed, reducing development time and making it easier to localize an application for different markets," as Apple puts it. Interface Builder stores user interface resources in "nib" files. It is itself a graphical editing enviroment, and, even if you're not a programmer, worth taking a look at just because of the interesting interface examples it offers, particularly the way it uses drag and drop. Interface Builder is Apple's graphical editor for designing user interface components for both Carbon and Cocoa applications. Project Builder allows code and resources files to be grouped together arbitrarily, irrespective of their position in the file system.

Project Builder works with C, C++, Objective-C, and Java, though I got the distinct impression that Apple is emphasizing the ongoing roles of Java and Objective-C as Mac OS development platforms.

Project Builder and related tools provides project editing, search, and navigation, file editing, project building, and debugging facilities for Mac OS X development, including applications, tools, frameworks, libraries, plug-in bundles, and kernel extensions and device drivers. It supports the major platform initiatives of Mac OS X, including the Carbon and Cocoa frameworks, Java, and the new application packaging mechanisms that underlie OS X development. You can create an app with a command-line interface just by using frameworks.Īpplication Kit provides the raw materials for a GUI-widgets, ClipToScreen, etc.Īpple's main IDE for Mac OS-X, Project Builder provides templates for Carbon, Cocoa, and projects. NSDictionary is like a hash table, but one that allows you to use key value coding, in which an object has keys and values. A framework is essentially a class library.Ī Foundation framework provides basic functionality and fundamental data types, like:

A framework packages a dynamic shared library - including resources, libraries, documentation.

A set of frameworks with programming interfaces to Objective-C and Java.įrameworks are the Mac OS X shared libraries - frameworks distribute headers and libraries as a single file package.

An advanced object-oriented development platform.
