1 Going Mobile with iOS 2

So,you want to build an iOS app 2

'cause everyone wants one! 3

Apps live in an iTunes universe 4

Time to make a decision 5

It all starts with the iPhone SDK 6

Take alook around 7

Xcode includes app templates to help you get started 8

Xcode is a full-featured IDE 9

Xcode is the hub of your iOS project 10

Build your interface within Xcode 14

Add the button to your view 15

The iOS simulator lets you test your app on your Mac 17

iDecide's logic 18

Changing the button text 19

You're using the Model View Controller pattern 23

iDecide is actually a little simpler 24

What happened? 26

Use the GUI editor to connect UI controls to code 27

A component can trigger certain events 28

Connect your events to methods 29

You've built your first iPhone app! 31

Your iOS Toolbox 39

2 Hello,Renee! 43

First we need to figure out what Mike(really)wants 43

App design rules—the iOS HIG 48

HIG guidelines for pickers and buttons 51

Create a new View-based project for InstaEmail 52

The life of a root view 54

We need data 60

Use pickers when you want controlled input 61

Pickers get their data from a datasource 62

That pattern is back 63

First,declare that the controller conforms to both protocols 68

The datasource protocol has two required methods 70

Connect the datasource just like actions and outlets 71

There's just one method for the delegate protocol 72

Actions,outlets,and events 77

Connect the event to the action 81

Next,synthesize the property 85

Connect the picker to our outlet 86

Use your picker reference to pull the selected values 87

Your iOS Toolbox 96

3 Email needs variety 100

Renee is catching on 100

Make room for custom input 101

Header files describe the interface to your class 103

Auto-generated accessors also handle memory management 109

To keep your memory straight,you need to remember just two things 111

But when Mike's finished typing 121

Customize your UITextField 123

Components that use the keyboard ask it to appear 124

Ask the UITextField to give up focus 125

Messages in Objective-C use named arguments 127

Use message passing to tell our View Controller when the Done button is pressed 128

Where's the custom note? 132

Your Objective-C Toolbox 139

4 A table with a view 145

So,how do these views fit together? 145

The navigation template pulls multiple views together 146

The table view is built in 147

A table is a collection of cells 152

Just a few more drinks 160

Plists are an easy way to save and load data 162

Arrays(and more)have built-in support for plists 165

Use a detail view to drill down into data 168

A closer look at the detail view 169

Use the Navigation Controller to switch between views 179

Navigation Controllers maintain a stack of View Controllers 180

Dictionaries store information as key-value pairs 184

Debugging—the dark side of iOS development 187

First stop on your debugging adventure:the console 188

Interact with your application while it's running 189

Xcode supports you after your app breaks,too 190

The Xcode debugger shows you the state of your application 191

Your iOS Toolbox 195

5 Refining your app 198

It all started with Sam 198

Use the debugger to investigate the crash 200

Update your code to handle a plist of dictionaries 203

The Detail View needs data 206

The other keys are key 207

We have a usabilitv problem 213

Use a disclosure button to show there are more details available 215

Sales were going strong 218

Use Navigation Controller buttons to add drinks 223

The button should create a new view 227

We need a view&but not necessarily a new view 228

The View Controller defines the behavior for the view 229

A nib file contains the UI components and connections 230

You can subclass and extend View controllers like any other class 231

Modal views focus the user on the task at hand 236

Any view can present a modal view 237

Our modal view doesn't have a navigation bar 242

Create the Save and Cancel buttons 244

Write the Save and Cancel actions 245

Your iOS Toolbox 249

6 Everyone's an editor... 252

Sam is ready to add a Red-Headed School Girl 252

but the keyboard is in the way 253

Wrap your content in a scroll view 255

The scroll view is the same size as the screen 257

The keyboard changes the visible area 260

iOS notifies you about the keyboard 262

Register with the default notification center for events 263

Keyboard events tell you the keyboard state and size 269

The table view doesn't know its data has changed 288

The array is out of order,too 292

Table views have built-in support for editing and deleting 300

Your iOS Development Toolbox 313

Sam has another project in mind 314

7 We need more room 316

DrinkMixer on the iPad 316

The iPad simulator 318

The HIG covers iPads,too 319

Use Xcode to build your Universal app 326

Check your devices 334

Rotation is key with iPad 337

A persistent view problem 345

Don't forget the tableview 346

Your iOS Development Toolbox 359

8 Enterprise apps 362

HF bounty hunting 362

A new iPhone control 368

Choose a template to start iBountyHunter 372

There's a different structure for universal apps 374

Drawing how iBountyHunter iPhone works 376

and how it fits with the universal app 377

Build the fugitive list view 382

Next up:the Captured view 384

A view's contents are actually subviews 392

After a quick meeting with Bob 394

Core Data lets you focus on your app 396

Core Data needs to know what to load 397

Core Data describes entities with a Managed Object Model 398

Build your Fugitive entity 399

Use an NSFetchRequest to describe your search 410

Bob's database is a resource 417

Back to the Core Data stack 418

The template sets things up for a SQLite DB 419

iOS Apps are read-only 421

The iPhone's application structure defines where you can read and write 422

Copy the database to the Documents directory 423

Your Core Data Toolbox 444

9 Things are changing 446

Bob needs documentation 446

Everything stems from our object model 449

The data hasn't been updated 452

Data migration is a common problem 453

Migrate the old data into the new model 454

Xcode makes it easy to version your data model 455

Core Data can“lightly”migrate data 457

Here's what you've done so far 461

Bob has some design input 462

Your app has a lifecycle all its own 472

Multitasking rules of engagement 473

A quick demo with Bob 476

Use predicates for filtering data 478

We need to set a predicate on our NSFetchRequest 479

Core Data controller classes provide efficient results handling 486

Time for some high-efficiency streamlining 487

Create the new FetchedResultsController getter method 488

We need to refresh the data 493

Your Data Toolbox 499

10 Proof in the real world 502

For Bob,payment requires proof 502

The way to the camera 511

There's a method for checking 521

Prompt the user with action sheets 522

Bob needs the where,in addition to the when 528

Core Location can find you in a few ways 534

Add a new framework 536

Just latitude and longitude won't work for Bob 544

Map Kit comes with iOS 545

A little custom setup for the map 546

Annotations require a little more work 553

Fully implement the annotation protocol 554

Your Location Toolbox 561

11 Natural interfaces 564

Bob needs that iPad app,too 564

iOS HIG user experience guidelines 567

Iterate your interface,too 568

BountyHunterHD is based on a split-view controller 570

Unifying the custom stuff 580

It seems we have a problem 585

UIWebview has lots of options 586

HTML,CSS and Objective-C 588

Using UIWebView 588

Your NUI Toolbox 599
