iOS Architecture iOS Architecture > Core OS

Core OS Manage the virtual memory system, threads, the file system, the network, and inter-‐process communica4on with the frameworks in the Core OS layer. This layer encompasses the kernel environment, drivers, and basic interfaces of iO.

OS X Kernel Mach 3.0 BSD Sockets Security Power Management

Keychain Cer?ficates File System Bonjour


iOS Architecture iOS Architecture > Core Services

Core Services Gain access to fundamental iOS services with the frameworks in the Core Services layer. With these services, access files, low-‐level data types, Bonjour services, network sockets, and more. Use the frameworks in this layer if those in the Cocoa Touch and Media layers aren't sufficient for your needs.

Collec?ons Core Loca?on Address Book Net Services Networking

Threading File Access Preferences SQLite URL u?li?es


iOS Architecture iOS Architecture > Media

Media Create the best mul4media experience available on a mobile device with the frameworks in the Media layer.

Core Audio JPG, PNG, TIFF OpenAL PDF Audio Mixing

Quartz (2D)

Audio Recording

Core Anima?on

Video Playback OpenGL ES


iOS Architecture iOS Architecture > Cocoa Touch

Cocoa Touch Implement a graphical, event-‐driven applica4on in iOS with the frameworks in the Cocoa Touch Layer. In addi4on, use the frameworks in this layer to access key device features, such as user contacts.

Mul?-‐Touch Events

Mul?-‐Touch Controls

Accelerometer View Hierarchy Localiza?on

Tools XCode Interface Builder

Frameworks Founda?on UIKit

Language Objec?ve-‐C


iOS Development Key Concepts > Language > Objective-C

Main Characteris4cs Superset of C (Can be mixed with C and C++)

Single inheritance Categories define behavior across classes

Dynamic run?me Object Messaging

Class Defini?on Proper?es

Enumera?on New Types (Anonymous classes, Class, Selector)



Extension Source Type

.h Header files. Header files contain class, type, func?on, and constant declara?ons.

.m Source files. This is the typical extension used for source files and can contain both Objec?ve-‐C and C code.

.mm

Source files. A source file with this extension can contain C++ code in addi?on to Objec?ve-‐C and C code. This extension should be used only if you actually refer to C++ classes or features from your Objec?ve-‐C code.

Delega?on to perform applica?on-‐specific behavior



UIApplica2onDelegate

An object to par?cipate in applica?on lifecycle.

Call implement methods witch UIApplica?on will call.

Manages status bar, applica?on icon badge



Info.plist file

Property List describes an applica?on.

Icon appearance, status bar Style, orienta?on,…

Editable on XCode.


iOS Development Introduction > Hello World


iOS Development Introduction > Model View Controller

•  The controller subsystem decouples the model and the view.


iOS Development Introduction > Model View Controller

Layer Descrip4on

Model Model objects encapsulate the data specific to an applica?on and define the logic and computa?on that manipulate and process that data.

View A view object is an object in an applica?on that users can see. A view object knows how to draw itself and can respond to user ac?ons.

Controller

A controller object acts as an intermediary between one or more of an applica?on’s view objects and one or more of its model objects. Controller objects are thus a conduit through which view objects learn about changes in model objects and vice versa.
