1. Getting Started: Getting mobile with iOS

So you want to build an iOS app... Welcome to the Apple universe! iOS apps are written in Objective-C It all starts with the SDK Pin Xcode...you’re going to be here a lot Meet Sue, your new boss Xcode and Git...new best friends Xcode is the hub of your iOS project The iOS simulator Your code is stored in source files Code Editor, Hub...and debugging, too One iPhone, two iPhones, red iPhone, blue iPhone... Your iPhone Development toolbox

2. Basic iOS Patterns: Building from scratch

iOS apps run full screen, but there’s a lot going on Model-View-Controller is a design pattern Get started with Xcode and Git Design time! Design time...redux Cosmetic changes are easy in Xcode You could code this if you’re into that kind of thing... iOS controls are more than skin deep

The code your button calls is an Action

You’ll create the action using the Xcode GUI editor Connect your controls to your actions

This is your control This is your controller... Your control has events... ...and those events can connect to Actions So about these classes and interfaces we keep writing...

So how do we get to that text? Properties handle creating getters and setters Create a property for that text field You connect your controls to outlets

An IBOutlet references something in the UI

Twitter, the easy way... Your iOS Basics toolbox

3. Interlude: Syntax

Classes: Interface and Implementation Header files describe the interface to your class Properties are about efficiency

Property attributes talk to the compiler

Message passing: How Objective-C gets around Speaking of messages.... Your Syntax toolbox

4. Tables, Views, and Data: A table with a view

Congratulations! SpinCity browsing app overview The way iOS apps work Using the touch screen.... Hierarchical data—get out your table view

Use table and detail views together to represent hierarchical data

We need to hook these views together...

The navigation controller gets you around in your views

Three views in one template Use MVC to separate your concerns... Adding a new class Properties expose class attributes Data Access Objects hide low-level data access You’ve built your DAO! A table is a collection of cells

Storyboards can layout custom table view cells too

Your View toolbox

5. Multiview Applications: It’s all about the details

An app with a view...

Detail views are everywhere

Table views don’t always look like...tables Change your UIViewController to a UITableView Controller Layout for the new detail view Layout your view within the storyboard Design the rest of the view dynamically Segues connect view controllers Connect your scenes in your storyboard Segues let you prepare for a new scene Update your prepareforSegue callback There’s an app a list for that Create a new property list You need to load each album from the plist Convert your data to plists in one easy step Your View toolbox

6. The Review Process, Design, and Devices: How to live with Apple

It’s Apple’s world...you’re just living in it Device checking... it’s not optional Device checking case study: the camera iOS handles the heavy lifting Hmmm... supported device, missing feature The HIG helps, rather than hurting you You’ve already gotten used to the HIG... Design = look + feel iOS 7 Top 5 More to think about: your iPad is not your iPhone Your Apple toolbox

7. Basic Core Data and Table View Cells: Reruns are hard to find

This is your application This is your application on data Introducing Core Data

But wait, there’s more!

...and speaking of data The Gilligizer app Core Data starts with...data Core Data works with entities

We need to define the entity for Core Data

Core Data describes entities with a Managed Object Model Build your Show entity Our generated Show class matches our Managed Object Model NSManagedObject also implements the properties You have an object...now present it. Present each entity in Gilligizer Your Core Data toolbox

8. Implementing search with core data: Looking for info

The app is working, but it’s limited... Use an NSFetchRequest to describe your search Let’s give it a shot... iOS 7 has Core Data and UIKit support for searching SearchDisplayController handles just about everything Use predicates for filtering data

NSFetchRequest concepts are nearly identical to SQL

The NSFetchRequest predicate controls what data is returned

The Search Bar lets you know what’s happening through a delegate

It was a trick question... Your searching toolbox

9. Core data, mapkit, and core location: Finding a phone booth

Everything old is cool new again An app, an iPad, and a phone booth iOS apps are read-only (well, kind of...) An iOS application structure defines where you can read and write data

Get the photo path and then write that path to the filesystem!

Enter... UIImagePicker Prompt the user with action sheets

Action sheets lead to...dactions!

Where Who... are you? Where Who, who? Core Location can find you in a few ways

Core Location relies on the LocationManager

Map Kit comes with every iOS device Annotations require a little more work finesse Fully implement the annotation protocol Your kit Toolbox
