Overview

Introduction to iOSThe BeginningsApple's Steve Jobs introduced the iPhone to the world on January 10th, 2007iOS actually began life with a different name: OS XWhen the original iPhone launched, the OS was called "iPhone OS" and it kept that name for 4 years.Its use is extened to iPod Touch, iPad and Apple TV.

iOS 1: The iPhone is bornWindows Mobile, Palm OS, Symbian, and even BlackBerry were all established systems in 2007, with a wide and deep array of features.Comparatively, the iPhone didn't support3Gmultitasking3rd party apps, MMSExchange push email and tethering, it hid the file-system from usersediting Office documentsvoice dialing, and it was almost entirely locked down to hackers and developers.iOS 1: The iPhone is bornFew of the many innovations were revolutionary for the mobile industry.The core iOS user interface.Mobile Safari web browserGoogle MapsVisual voicemailThe software keyboard

Map Kit FrameworkProvides a programming interface that enables you to build map based capabilities into your own applications.Display scrollable maps for any locationmap corresponding to the current geographical location of the device and annotate the map in a variety of ways.Other FrameworksPush Notification Service : Allows applications to notify users of an event.

Message UI Framework : Allows users to compose and send emails from within the application.

Other FrameworksGame Kit Framework : Provides peer-to-peer connectivity and voice communication

Address Book UI Framework : Enable user to access contact information from the iPhone address book from the application.

Other FrameworksiAd Framework: Allows developers to include banner advertising within their applications.

Event Kit UI Framework: Allows the calendar events to be accessed and edited from within an application.

Objective-CObjective-C is an object-oriented programming language used by Apple primarily for programming Mac OS X and iOS applications. It is a super set of C.Objective-C source code files are contained in two types of files:.h header files.m implementation filesClasses

The @interface Section@interface NewClassName: ParentClassName{ memberDeclarations;}methodDeclarations;@end

Instance variablesClass and instance methods

The @implementation Section@implementation NewClassNamemethodDefinitions;@end

The @class Section@class Classname;

Used as forward declaration to reference another class defined in another file.#import @interface Fraction: NSObject{ int numerator; int denominator;}-(void) print;-(void) setNumerator: (int) n;-(void) setDenominator: (int) d;@endExample

@implementation Fraction-(void) print{ NSLog (@%i/%i, numerator, denominator);}-(void) setNumerator: (int) n{ numerator = n;}-(void) setDenominator: (int) d{ denominator = d;}@endint main (int argc, char *argv[]){@autoreleasepool{Fraction *myFraction; // Create an instance of a FractionmyFraction = [Fraction alloc];myFraction = [myFraction init];[myFraction setNumerator: 1];[myFraction setDenominator: 3];NSLog (@The value of myFraction is:);[myFraction print];}return 0;}Synthesized Accessor Methods

@interface Fraction : NSObject{int numerator;int denominator;}@property int numerator, denominator;

Properties are often your instance variables. The Objective-C compiler automatically generates or synthesize the getter and setter methods using @synthesize directive as shown below.#import Fraction.h@implementation Fraction@synthesize numerator, denominator;

ProtocolsA protocol declares methods that can be implemented by any class.@interface Myclass:NSObject {..}@end; CategoriesA category in Objective-C enables you to add methods to an existing class without the need to subclass it. You can also use a category to override the implementation of an existing class.

Data Types

To write an iPhone application, you have to install Xcode and the iPhone SDK.

Sqlite (http://www.sqlite.org/index.html) is an open source embedded database. The original implementation was designed by D. Richard Hipp. In 2000 version 1.0 of SQLite was released. This initial release was based off of GDBM (GNU Database Manager). Version 3.0 added many useful improvements.Open source RDBMS.Single File databaseWorks as library not database.Major users of SQLite: Adobe (PS and RE), Apple(mail and Safari), Google (Desktop and Gears) etc..Thus, widely used in testing, analysis and embedded devices. Data Management -SQLite

Add the Framework for SQLite i.e.libsqlite3.0.dylib

In xcode v4+, select project then in project settings editor select summary. Scroll down to frameworks and select add (+).

In the .h file #import sqlite3.h

Open connection with path and file. You can use any file format such as .db, .sql and .sqlite

Configuration Steps

Problem with foreign keySingle userNo proceduresNo securityProblem with 64bit system.SQLite DisadvantagesA table view is an instance of the UITableView class in one of two basic styles, plain or grouped.Table views have many purposes:To let users navigate through hierarchically structured dataTo present an indexed list of itemsTo display detail information and controls in visually distinct groupingsTo present a selectable list of optionsTable Views

Main Window Single View vs Table view bases ArchitecturemainApp DelegateView ControllerScreen viewView ControllerMain Window mainApp DelegateView Controller3Screen viewView Controller3View Controller2Screen viewView Controller2View Controller1Screen viewView Controller1Start a new project.Open Storyboard.Add three table view controllers (TvC1, TvC2, TvC3)Add Navigation Controller: select TvC1, Editor -> Embed in -> Navigation Controller.To connect, select TvC1 drag TvC1 cell to TvC2 toolbar and select push segue. select each table view Cell to give a Identifier in table view cell properties.Select the segue and give the identifier name to each.Create three obj-c classes extended from UITableViewController. Link these classes to the views on storyboard.Add barbuttonItem to each view toolbar and link them to IBAction buttons in respective viewControllers.

Steps

SegueLink the two views using Segue..

Update methods:numberOfSectionsInTableViewNumberOfRowsInSectioncellForRowAt

Built-in management of undo and redo beyond basic text editing.Automatic validation of property values.Maintaining the consistency of relationships among objectsGrouping, filtering, and organizing data in memory and in the user interfaceAutomatic support for storing objects in external data repositories

Core DataA framework that supports creation of model objects that encapsulate your application data and logic in the Model-View-Controller design pattern.https://developer.apple.com/library/mac/#referencelibrary/GettingStarted/GettingStartedWithCoreData/

Create an empty Application * make sure Use Core Data is checked.

Steps

Manage object context: gateway into storing data objects.These data objects belong to the view content. Propagates all the changes to the file systemPersistent storage cordinator: adaptor between files on the device and the application.

Sqlite is used as the database.

A simple Core Data stack

Create classes of each Entity

Update view controller methods to ascess model classes.

Create category (on the top of the existing files) for additional functionally such as sorting, filter rows etc...
