Introduction to iPhone development
and Xcode
 iPhone OS consists of a number of different software layers .
 Each of which provides programming frameworks for the
development of applications that run on top of the operating system
 These operating system layers can be presented diagrammatically
as illustrated in the following figure:

Overview of the iOS ArchitectureOverview of the iOS Architecture
 As previously mentioned, iOS consists of a number of different
software layers, each of which provides programming frameworks for
the development of applications that run on top of the underlying
hardware.

Platform Components
 Tools ---- XCODE
 Language– Objective C/C++
 Framework ---Cocoa touch Layer
 Design Strategy --- MVC

Cocoa touch LayerCocoa touch Layer
 The Cocoa Touch layer provides the following frameworks for
iphone and iPad app development:
1) UIKit Framework (UIKit.framework)
2) Map Kit Framework (MapKit.framework)
3) Message UI Framework (MessageUI.framework)
4) Address Book UI Framework (AddressUI.framework)
5) Game Kit Framework (GameKit.framework)
6) iAd Framework (iAd.framework)
7) Event Kit UI Framework
8) Accounts Framework (Accounts.framework)
Twitter Framework (Twitter.framework)
 Note:- details of all framework show developer.apple/documentation sites

The iOS Core Services LayerThe iOS Core Services Layer
 He iOS Core Services layer provides much of the foundation on
which the previously referenced layers are built and consists of
the following frameworks.
1)Core Video Framework (CoreVideo.framework)
2)Core Text Framework (CoreText.framework)
3)Image I/O Framework (ImageIO.framework)
4)Assets Library Framework (AssetsLibrary.framework)
5)Core Graphics Framework (CoreGraphics.framework)
6)Core Image Framework (CoreImage.framework)
7)Quartz Core Framework (QuartzCore.framework)
8)OpenGL ES framework (OpenGLES.framework)
9)GLKit Framework (GLKit.framework)
10)NewsstandKit Framework (NewsstandKit.framework)
11)address Book Framework (AddressBook.framework)

Introduction XcodeIntroduction Xcode
 Xcode is the complete toolset for building OS X and iOS
applications.
 The Xcode IDE understands your project’s every detail, identifies
mistakes in both syntax and logic, and will even fix your code for
you. Quite simply help you write better code.
 Xcode has a brand new user interface, built upon proven
technologies that Apple itself uses to build OS X and iOS, and
that have produced over a quarter million OS X and iOS apps.

Single Window
 As an experienced Xcode user, the first thing you will notice about
Xcode is that the many windows used to perform the development
tasks you work on every day have been consolidated into a single
window.
 The Xcode work area has several unique UI elements that make it
easy to work on many different tasks, even multiple projects,
without cluttering your work area. Your editor is always front
and center.

Navigators
 On the left side is a collection of navigators, including
the list of files in your project, sorted symbols, a central
search interface, issue tracking, debugging data with
compressible stack traces, active and inactive
breakpoints, and a persistent collection of logs.
 The unified navigator UI provides live filtering of content
and search results, so you can focus on your
current task.

Jump Bar
• At the top of every editor pane is a path bar showing the relative
location of your current file.
• Click any location in the path to immediately jump to any other file
at that level.
• This is the Jump Bar, and it is so efficient you may wish to dedicate
your entire desktop to source code, quickly jumping from file to file.

Interface Builder is Built-in
• In Xcode 4, Interface Builder has been completely integrated within
the Xcode IDE –– there is no separate application.
• Selecting an interface file (.nib/.xib/.storyboard) in your project will
open the IB editor within Xcode.
• Opening the right-hand Utility area will show the full complement of
interface inspectors, as well as the library of controls and UI objects.
• Drag a control from the library, and drop onto the canvas, to layout
your OS X or iOS app.

Apple LLVM Compiler
• Apple LLVM is the next-generation compiler technology powering
Xcode .
• Based on the vibrant open source LLVM.org project led by Apple
engineers, the Apple LLVM compiler is modern thinking, tuned for
iPhone, iPad, and the multi-core Mac.

Fix-it and Live IssuesFix-it and Live Issues
• The Apple LLVM engine is constantly working in the background
to understand your code.
• In the editor, the new Live Issues feature uses that
understanding to alert you to coding mistakes as you type.
• Just like a word processor highlights spelling errors, Xcode 4
highlights common coding mistakes, without the need to click
‘build’ first.

Fix the problem automaticallyFix the problem automatically
Beyond just reporting errors, the IDE is intelligent enough to fix the
problem for you.
In many cases Xcode will not only report an error, it will present a
solution as well.
Click the error to see the available Fix-its, such as correcting an
assignment to a comparison, repairing a misspelled symbol, or
appending a missing semicolon. A single keyboard shortcut will
instantly have the error repaired, and let you continue coding.

iOS Simulator
• The iOS Simulator runs your application in much the same way as
an actual iOS device.
• Because it is quick to launch and debug, the iOS Simulator makes
for a perfect test bed to make sure your user interface works the
way you intend, your network calls are correct, and that the views
change correctly when the phone rotates.
• You can even simulate touch gestures by using the mouse.
• The iOS Simulator is a great time saver.

Storyboards Help You Design Your UserStoryboards Help You Design Your User
InterfaceInterface
When you implement your app using storyboards, you use
Interface Builder to organize your app’s view controllers and any
associated views.
 The visual layout of Interface Builder allows you to understand the
flow through your app at a glance.
 You can see what view controllers are instantiated by your app and
their order of instantiation.
 But more than that, you can configure complex collections of views
and other objects in the storyboard

 A scene represents an onscreen content area that is managed by
a view controller. You can think of a scene as a view controller and
its associated view hierarchy.
 You create relationships between scenes in the same storyboard.
Relationships are expressed visually in a storyboard as a
connection arrow from one scene to another. Interface Builder
usually infers the details of a new relationship automatically when
you make a connection between two objects.

common transitions needed between twocommon transitions needed between two
different view controllers:different view controllers:
 A push segue pushes the destination view controller onto a
navigation controller’s stack.
 A modal segue presents the destination view controller.
 A popover segue displays the destination view controller in a
popover.
 A custom segue allows you to design your own transition to display
the destination view controller.
